    Rubena Scylla Tires

    Does anyone have any experience with these tires? Weight is advertised at 540 Gr and they look like a mix between an Aspen and an Icon. Just wondering...

    Just recently heard about these. It's a Czech brand. Just getting some marketing cranked up here in North America to get the word out. I don't even know who their distributor is.

    They do look interesting. They have tubeless ready variants and claim high volume.

    PromoLogic was handling Rubena 4-5 years ago. The (26") tires were good, if "small" in their nominal sizing.

    The Scylla tread worked well. No 29" models at the time.

    The trouble with common sense is it is no longer common

    Rubena in the US and in 29'r!

    I work for the distributor for Rubena in the US. We have both the Scylla and the Kratos in 29x2.25, Tubeless and what they call Racing Pro. The Tubeless version is compatible for tubed setups, conversions such as Stans and also UST setups. The Racing Pro is compatible with tubed and conversion setups.

    It's true that we're just starting to get the word out about these tires. All of the shop feedback I've been getting has been very positive. The tires are light, they have a 127tpi casing while still having reinforced sidewalls, they hook up really well and have a pretty low rolling resistance.

    If you have an interest in picking some of these tires up, encourage your LBS to contact Cyclone Bicycle Supply. If anyone has any questions please post up, I'll find out what you need.

    Thanks.

    29x2.25 @ 540 Gr?

    You really need to make a page that displays all of the different models and shows tread patterns. The mfg website is horrible to navigate.

    Rubena USA website and other sundries...

    Xeno, Rubena USA is in the process of putting a site together. It won't be up for a little bit, but expect one that's easily navigated and well thought out.

    About the weight on the Scylla, yeah, 540g, they're the real deal. Wait for more options to come out in time for next Spring too. Dual compound tires, wider ranges and 57.8% more awesome. You're going to hear a lot about this brand over the next year.

    Sounds like a great tire.

    I ended up purchasing Vulpines last night... after many hours of searching..

    There aren't enough good 2.1+ street duty/hardpack tires around the 500g area for 29ers and that tread pattern looks like it'll roll relatively well...

    One problem, Vulpines are over 600 grams. Apparently more research was needed

    Agreed. Also a confirmation of the size and weight would be nice. Can we see a pic of the actual tires instead of just a CGG? Any sidewall protection versions available or coming?

    Saw these in person at a bike shop in Dallas, TX. They look pretty interesting. They were on the shop owner's bike and he says he really likes them. I'm thinking about trying a set of these when my current tires need replacing.

    I'd disagree with you on that. Schwalbe tires in the same style range retail for about $80, same for similar Maxxis tires. Kenda come sort of close but don't really have the features the Rubenas offer. As hard as it is to accept, rubber prices have increased about 35% coming from Asia and this is the price you'll see for mountain tires on the top end of performance characteristics.

    My background is mostly urban and road cycling, so I'm familiar with the high cost of rubber. Hell, I paid $55 or $60 for Conti Grand Prix in the late '90's. I think mountain tires have taken a lot longer to see the effects of material and manufacturing cost increases but I'm pretty sure they're here to stay. Sorry you think they're ridiculously priced.

    I know rubber has gone up in price but $65 is still far too much for me to spend on one bicycle tire. I wouldn't even bother paying for $50 tires. It's one of the top reasons I have bought older model Geax Saguaro tires lately. They're very reasonable as you can find them for under $40, they work great for me, they wear like iron and you're buying really good tires not marketing hype and race day Euro fashion and mystique. It's really hard for me to buy the currency differences too when most tires are made in China or other low cost areas like Indonesia. All of which shouldn't imply that you shouldn't choose to use your own resources to buy the spendiest of tires in any way you see fit, just leave me out of it thanks.

    Tires are the only thing that keeps my wheels glued to the ground. If I have to spend $$$ on a tire so I know it will stick and then break predictably when I throw the bike into corners it's well worth the extra $20/30/40 over a cheaper, longer wearing tire.

    Each to their own but I have to agree with lug.junkie: $65 for decent rubber (assuming these tires are decent rubber) is pretty fair IMO.

    If they have as much grip as mud wrestlers then it's a different story !!

    Thanks TL1 and Driver Bob. Both you have valid and real world points.

    TL1, if you'd rather spend less on tires than what these cost, that's fine, I have no problem with that. What I am a little disappointed about is this thread starting as a question about the tire, its availability and performance, and suddenly having been dismissed as "ridiculous" due to your personal perception about the price. Not really fair for a product you've never used and never seen. Nor is the assertation that the tires are based in "marketing hype and race day Euro fashion and mystique". Discussing the pros and cons of a product in these forums are all well and good, but you're not adding anything constructive to the conversation.

    Driver Bob, I'm in the same boat as you, I'll pay for rubber when it does the best job for the situations where I use it. If you want to see the Rubena tires in person let me know and I'll direct you to the closest place.

    Thanks.

    Matt, How about I do some real world SS testing on those bad boys for you. I live in So Utah so I can put them through the ringer in a year on really varied terrain.

    PM me if you want my shipping address.

    Let me think about that. I have 4 more posts after this one before the site will let me PM anyone, so you'll have to wait at least that long.

    The price is in line with other high end tires, no worries there. Agree with above- I'd like to see real pics. Also, I can't seem to find the Kratos on the website.
    Worked at Trek/Fisher dealer 2008-2013. Only a little biased.

    Didn't mean to come off that way or in any way diminish those that enjoy spending that kind of money on their passion. It won't be me doing it though. I should have said "That's ridiculous amount of money for a tire (for me)". My Geax Sags are the best tire I've found for my kind of trail riding and make me happy everytime I ride them.

    Prices are high because we will pay it. Not because of rubber prices. I buy tires for my car that cost $70 each. and the schwalbe's on my bike are $75 each. The problem with cyclist is that we think we need or want things and will pay whatever to get them. (im guilty too). for instance: im a recreational trail rider that rides for fun and fitness. I dont need the weight savings of x0 drive over x9 or carbon bars and thomson masterpiece post, but do i want it...hell yeah. I can afford it and i want it so i buy it. Do i know its all overpriced...hell yeah.

    GT, I think I hear what your saying,the guy selling bike tires and the guy selling car tires each have to pay the same for a gallon of milk or gas. I think Tex is right we are getting riped off becuse we let it go on and on becuse of our wants.. I loved the schwalbe rr but they have crossed the line with me I will most likely never buy another one of there tires.. so if your saying that the scale is differnt then please explain why a bike tire cost the same as our car tires. I'm not to smart, I'm problythedumstturdinthepenut

    lug.junkie, I like the looks of your tire and it loks like it's going to cost less than the RR I was running on the rear I think that tire msrp is about $100 I got 5 24 hr races and about 150miles of riding out of it and I would not have used it at the last race had I know how bad that tire was (thin). 540g & 70$ isn't bad and also we would like 2.0 470grams. Your tire does look like the Max Aspen I have them on the front of my bikes and live in the mid north

    The amount of car tires produced makes what numbers in bicycle tires produced look like a handful of bicycle tires next to a mountain of car tires.

    The materials cost is obviously a factor with such small production numbers.

    Car tires can cost less since the numbers sold support more of the company and pay for the original costs to open molds, etc much more quickly than bicycle tires can.

    If bicycle tires, specifically mountain bike tires, were made and sold in far greater numbers you would realize some cost reductions.

    Also- Comparing a standard car tire to a high performance, high tech mountain bike tire isn't a fair comparison either. Just from a technical standpoint. Look at the cost of a high tech, high performance car tire and the example changes dramatically.

    The whole dollars to dollars comparison becomes a much different story if you consider more than what is skin deep.

    Ok thank-you Ted that all sounds good so that people will be willing to pay a $100.00 msrp on a tire. but like said for ME I will not buy any more schwalbe RR evo it was a good tire but not that good I just think that what your saying is true BUT! and a big one at that, if everyone quit buying the RR how much do think that tire will go down in price in like six months.

    Economies of scale notwithstanding, what I highlighted is what often gets forgotten for a lot of bike stuff, not just tires.
    Over the last 20 years of working in shops, I've often heard someone's shock at $80 tires, or a $5000 bike.
    The fact of the matter is, you can buy an exact replica of a bike that has won World Championships, or World Cup races for >$10k. How much would it cost to buy a World Championship-winning motocross bike? Or F1 car?

    I have tried these in 26" in South Africa where they are quite common, and they were light and rolled fast, but came up very narrow. I slit a sidewall after about 5 rides and ended up giving the other one away. I was running them tubeless, set up wasn't too much of a problem.

    Mountain biking on a whole compared to other hobbies can be inexpensive. A $4000 mountain bike is much more accessible than a $100,000 car, and therefore more commonplace.

    @GT i understand economies of scale, but this particular market is more driven by demand.

    Back on topic, I think I will be a guinea pig for this tire. It looks like a reasonable tread pattern for me, and if it at the advertised weight and holds up tubeless, could make a good reasonably priced tire for me. Is there any difference in the two versions other than one is a "race" tire and one is advertised as tubeless? I may opt for the tubeless version though it is a bit porkier.

    Go read the product reviews on Pinkbike, every third comment is some variation of "that price is ridiculous, my [cheaper part] is just as good, people who pay this are idiots." It's not very helpful.

    There are plenty of reasons to pay more or less for things, and plenty of options out there for everyone's budget. Just straight-up saying something is not worth the money is not helpful at all.

    Some people might be paying $280 to put tires on their autos but mine are $1500/set. Am I an idiot? Is $1500 too much for tires? So how much should I be paying? There is no way to answer that question. You just can't generalize and say $$$$ is too much without having any information.

    I drive a 4WD, use it off-road, on roads that are not in good shape and in extreme winter conditions. I need decent tires and $1500 is what they cost. You can spend a LOT more than that for truck tires if you want.

    Goes the same for bikes... I have a lot invested in my ride, and I use it all the time. I'll buy the tires I need and can afford, and if they cost $80 or $100 then that is what they cost. It's not some existential problem it's just production, supply and demand.

    WR, the closest place to Dallas proper is Cadence Cyclery in McKinney, TX they have purchased these tires from us in the recent past. We also sell to Oak Cliff in Dallas though they haven't signed on to these tires yet. Please let me know if you have any other questions and if you pick up a pair, let me know what you think about them. Thanks for asking.

    That won't happen, that's what.

    I get that you wish tires were cheaper. Heck- we all do. But it ain't gonna happen due to the pricing structure now. The increases are not chasing enough people, (yourself not withstanding), away from the market place to make the changes you are hoping for.

    "if" that did happen, well of course, you'd be right. But.......(see first sentence above).

    Don't worry about it TL, we all get a little carried away while typing away on the interwebs. If you're ever in the Portland, OR area give me a heads up and we'll ride, I may even have a demo pair for you to try out.

    What you arent considering is the cost of raw rubber...wich is thru the roof.

    I work for goodyears commercial tire division and our truck tires ( think 18 wheeler semi tires) have gone up 67% in the last year due to rubber costs and demand.

    Take in to account that a bike tire takes less rubber so they dont buy as much so their price is higher.

    lug,

    It would be nice to see some pics of the Scylla and the Kratos mounted? Anime just doesn't do it for me.

    Thanks

    Edit: After a little digging I found this pic but better pics with rim specs couldn't hurt either.

    I just ordered some in for the shop. I don't have them mounted on any rims yet, but if I get some time over the weekend I might just to measure them up and czech out their shape. The casing feels nice and supple, mush like a Schwalbe. The weights are a bit over their advertised weights, but are not by any means heavy. The Scylla weighs in at 620g, 80g over the advertised 540g. The Kratos comes in a bit closer at 700g vs. the advertises 650g.

    Tires that do not sell get discontinued. The price may go down as the remaining stock is blown out, but then they are gone forever.

    ^^^ That is a bit farther away from the posted weight then they should be IMO. At that weight i will prolly just stick with the IKON. no real complaints about it yet.

    I pulled the trigger on the Scylla and one Kratos tires, funny, the weight I got was closer to advertised weights but again over the advertised weight. 540 and actual was 575 for the Scylla.
    I have had them mounted and been running Orange Seal tubeless sealant in them on Arches and on a Crest and they are holding up very well and roll fast. 4 trips to Revile Peak Ranch, which it notorious for ripping off knobs on tires, will kill a nano in one trip, City Park, Walnut, 3 rides at Rocky Hill and one ride on the Greenbelt and Travis country. They grip very well and have not lost a knob as of yet.
    I did a 40 miler on the road the other day, lead out for a marathon, and they rolled very smooth.
    In Austin you can get the tires at Mac's Cycle Werks, in both 26 and 29 sizes and are priced VERY competitively, not sure if they will get in trouble but less than MSRP by a bit.

    Just curious if if your running Kratos f and r or Scylla/Kratos. Just ordered a pair of Kratos. Wanted the taller more open knobs for slopper conditions. If I like them. Might pick up a Scylla for the rear, when things dry out.

    I'm running Scylla front and rear most of the time and when I want more bite I am running the Kratos on the front for times I want more "bite".

    Just mounted up a Krato's on a Stans 355 rim. I must say I am disappointed in both the volume and width for a 2.25 tire. The Crossmark 2.1 it replaced has noticeably more volume and width than the Kratos. Bought them for a sloppy winter tire. Maybe the narrowness will work out for the better.

    Widest measurement from sidewall to sidewall was 1.93". Widest point from side knob to knob was 2.09". I'm sure they might settle in and get a little wider, but not that much. Granted a 355 rim is'nt that wide, but was still hoping for more volume from a claimed 2.25 tire. Clearly the Crossmark it replaced is wider and has more volume.

    They did however mount easily using Stans sealent on 355's. These were also the race version with DTC gray sidewalls.

    Will mount the other one in a couple of days and take them for a spin after the holidays and weather gets a little better. Maybe the ride will be better than the initial disappointment of the size.

    Agreed !! Hows the volume on the vulpines ?? and are they faster than 2.1 SB8 ??

Haven't ridden them much yet, but they feel like they're going to wear out fast, but they are really light. :P

    540 grams is the claimed weight for the 26" tire. The claimed weights for the 29" tires are
    Scylla - standard 590, tubeless 640
    Kratos - standard 660, tubeless 690

    I just got two standard Kratos', they weighed 662 and 672 grams.

    EDIT: I just got two tubeless Scylla's as well, 602 and 609 grams. UNDERWEIGHT...YAY!

    I'm stoked the tires are getting out there and being ridden by folks in the field. I am about to put a set of the Scylla's on my 26" hardtail for a race here in Oregon. Please, I'm very interested in feedback and would appreciate unfiltered thoughts to pass to the folks in CZ. PM me, post on this thread, anything you like. Thanks for the discussions everyone.

    How do these tyres work? Do they mount easily tubeless on Flow rims? Tight fitting and hard to mount? What is the rolling resistance of Kratos and Scylla?

    The Kratos DC model was a little snug on 355 rims. I didnt think mounting was to bad. There was several pin holes in the pair. Had to lay them on thier sides, rotate and add air a few times before they sealed. One had a valve stem issue. Not the tires fault.

    I'd say rolling resistence is good. Not as fast as a Crossmark, but certainly no Nevegal. Grip is good. Sidewalls are 120 TPI and appear to be adequate. Overall, they look to be a very well made tire.

    Now for what I did'nt like. The pair only averaged 2.05" and the volume is'nt that great. Was really hoping for something closer to the advertised 2.25" Seeing how I ride a HT. I really wanted the volume. Only rode them on one 12 mile ride. Went back to a fatter tire.

    I really want to like this tire. Everything about it is good. Except the size. It makes a Crossmark look big. Bontrager XDX/29-3's look huge compared to the Kratos.

    Hey Mojo. Just curious as to whether you have gotten out on the Kratos yet? I have heard from a number of people who had the same concern as you, the lack of volume as compared to other tires in the same class. I have then heard some of the same folks come back and say they really didn't miss the volume. I would like to know if the volume is a practical issue or a perception issue.

    Thanks to you all for this thread. I really appreciate all of the feedback.

    Mounted the Kratos DTC a second time. After several rides I still like the tires as a whole. Just wish they had more volume and truer to the advertised 2.25"

    $64.95 retail I believe.

    First ride was today and they were amazing. It's a fast XC tire with grip! It set up tubeless on a carbon rim and zero leaks overnight. The sidewall seems to have protection but it seems really soft and supple.

    The bike seems to ride smoother so I'll pay special attention to that. I had to keep checking air pressure since it's soft to sidewall pinch even at 30 psi.

    RUBENA CHARYBDIS 2.0's

    I have the CHARYBDIS 2.0's (Non UST). Does anyone know the minimum suggested PSI? I am flirting with lower & lower air, but don't want to snake bite by dipping to low. Also the 2.0 seem pretty narrow, more like 1.8's does anyone else run these?

    Thanks!

    Minimum suggested psi will always be up to you. The main variables are:

    - your terrain... aka how many sharp rocks
    - your weight
    - your riding style - how fast you ride, how much you jump, how smooth you are on landings and rough stuff.

    The tire is smallish and the sidewalls are soft so I would say 5 psi higher than your normal minimum. The true test is if you hit the rim... air up a little.

    Picked up a pair of Kratos last winter to try for $85 shipped (auction). If only they were closer to actual 2.25" Still averaging 2.05ish" mounted on a Stans 355.

    I think Rubena would give Schwable, Maxxis etc... a real race for thier money if only they had more volume and wider. The 2" lower volume 29er tire is in the minority for sales. Retool the mold and make this tire bigger.

    Look at Michelin. They make respectable tires. The only problem is. They are almost always to narrow. Therefore never really getting any market share.

    That might be good logic if...

    Some people might be paying $280 to put tires on their autos but mine are $1500/set. Am I an idiot? Is $1500 too much for tires? So how much should I be paying? There is no way to answer that question. You just can't generalize and say $$$$ is too much without having any information.

    I drive a 4WD, use it off-road, on roads that are not in good shape and in extreme winter conditions. I need decent tires and $1500 is what they cost. You can spend a LOT more than that for truck tires if you want.

    Goes the same for bikes... I have a lot invested in my ride, and I use it all the time. I'll buy the tires I need and can afford, and if they cost $80 or $100 then that is what they cost. It's not some existential problem it's just production, supply and demand.
    That might be good logic if there was some provable performance or durability increase with the $65 tires in this thread over a $30, 40 or 50 u.s. dollar tire.

    Holy wow! Lots of activity on this thread lately! Let me try and get in here per post:

    b-kul, we're working with the folks over at Rubena in CZ regularly to identify product they can produce for the North American market. As you can imagine, there are a lot of differences in trails, skills, and riding styles between Europe and the US. I'll make sure they know there's a call for a more aggressive 29'r tire.

    txxcrider, there's certainly a Zefyros in 29'r in all of the styles, we have them coming very soon. Keep in touch and I'll let you know when they land, you can ask your LBS for them at that time. Thanks for asking.

    For everyone talking about the volume, it's a bit of a strange thing. From my understanding all tires are measured for width on a specific rim, this used to be under the auspices of the ETRTO and now under ISO. The standard rim size is quite a bit wider than the typical rim used here. Don't ask me why, that's just the way it is. Anyhow, when measured on that rim spec the tire measures 57mm or 2.244 inches. When you move to a narrower than standard rim you taller crown and more narrow width. So there you go, I guess you can take it or leave it.

    tl1, unfortunately there's no real way to prove performance to someone other than having them on the tires. I could talk until I'm blue in the face about how great these are and all that but when it comes to it, they're likely going to act differently with you. Your riding style, local terrain, type of bike, and riding frequency are going to be the pudding in which you put your proof. That being said, these are the greatest thing since sliced bread, even Wonder is starting to sell them.

    Cheers!

    These are ridiculous money in the UK $30 which puts them $15 below the Aspen and $60 below the Racing Ralphs...

    I've got an XC race next weekend and they're pretty much 50% of the weight of my Hans Dampf's so i've just pulled the plug and ordered some of these.

    Thanks for all the thoughts lads... you made my mind up.

    Due to riding pavement. Ive pulled the Kratos off this weekend to save the tread. Its also really really dry here as well. So I switched to an older set of tires to wear out.

    Will throw the Kratos back on in late fall through winter. Hopefully we get some moisture.

    I'm in the market for a new set of tires and noticed your ads. here on MTBR. Upon doing a search, I discovered this thread.

    With all due respect, I must comment on the above. At 220lbs. I'm inclined to use the widest/most voluminous tires I can fit into my frame. I might have considered these as they are claimed to be 2.25 or 57mm. "francois" has posted photos showing that they are in fact 52mm. wide. That is in fact a 2.04" tire. By contrast my Schwalbe Nobby Nic 2.25 measures 58mm. on Sun Ringlé 28mm. (external width) rims.
    The trouble with having an open mind is that people will insist on trying to put things in it.

    Charybdis in action

    I have bought 2 Rubena tires recently: Scylla and Charybdis. The first one is 2,25 and the second one is 2,0. I have put both of the with tubes on my stock wheels – Mach 1, I believe and 2,25 looks wide for me. On my number one wheels: Reynolds MTN 29 I had Specialized Fast Track 2,0 and after giving Charybdis proper mountain go I have notice it is comparable size. So maybe it is the question what, you guys, put your tires on ;-) They had some heavy rains recently in Czech Mountains, and Charybdis on front performs brilliantly. I wish I had another one on rear rim, FT is to skippy for this conditions. Hope it dries out a bit. Will get another Charybdis as get back to Poland for sure.

    I've run the Scylla a couple of times now, about 35 miles total and it's pretty decent. Fast rolling, decent sizing ... i approve.

    I wouldn't wanna use it on anything muddy as it's obviously a dry trail tyre.. but for that job, it does a cracking job.

    I certainly understand your concern, I'm in a bit of the same boat as I am 200lbs and riding a hardtail. I will also collect all of your respect, so thanks for that. The point I was making concerning the width needs to be taken in the correct context, when these tires are mounted on rims with a narrow bead seat width (the outer width is immaterial for the sake of this conversation) the result is a narrower profile. Since these are manufactured in Europe there is a specific sized rim to calculate width, as rims on the US tend to go further toward narrow to reduce weight and rotational mass this will result in a more narrow tire on Euro brands.

    That being said, this tire will likely show its true width on a wider rim.

The point I was making concerning the width needs to be taken in the correct context, when these tires are mounted on rims with a narrow bead seat width (the outer width is immaterial for the sake of this conversation) the result is a narrower profile. Since these are manufactured in Europe there is a specific sized rim to calculate width, as rims on the US tend to go further toward narrow to reduce weight and rotational mass this will result in a more narrow tire on Euro brands.

    That being said, this tire will likely show its true width on a wider rim.
    I'm not really sure what you are trying to say. The SUN Ringlé rim I mentioned (28mm. external) has a 22.5mm. internal width, like the No-Tubes Flow rim. Both are considered to be fairly wide and made for more aggressive AM style riding. These are not skinny XC race rims. Also, I compared a Schwalbe 2.25 tire on the same rim as measuring 58mm. and it is also a European tire.

    If you are not aware, there is a review in the latest Dirt Rag magazine on the RUBENA KRATOS 29 X 2.25. (Issue 165, page 67) I quote from the review:

    "The tire is skinny, more like 2.0" than a 2.25", and there is not much height."

    "I like the tread but wish the Kratos were wider with more volume, or at least offered in larger sizes."
    The trouble with having an open mind is that people will insist on trying to put things in it.

    I would like to try the Scylla 29 but can't find them online...
    any suggestions in European sites?

    Thx!

    @CycloBicycles: I'm sorry, I am only the American distributor for Rubena and don't really know where to send you for Euro sites. There's this Euro site for Rubena, <html>http://www.rubena.co.hu/english/kulsok.html</html>, they may be able to help you with your quest.

    @Ronnie: What I'm trying to say is both Francois and Dirt Rag tested these tires on rims with a 19mm internal width, thus creating a more narrow profile of the tire itself. According to the ETRTO Standards Manual from 2007, the maximum tire width for a 19mm internal width is 50mm. This is because of the constriction and ovalization created by the rim when used with a wider tire. <html>http://www.slowtwitch.com/Tech/Implications_of_Rim_Width_2803.html</html>
    According to the graphic from the ETRTO in this link, your Sun Ringle rim has a width that should allow the full expression of the width of the Kratos as compared with Francois or Dirt Rag's rims. This has given me a little food for thought though. I'm going to measure my rim and tire and let you know what I come up with.

    Matt

    Iīam riding with the Scylla, 26x2.25 v96, right now. As I think, this is a fantastic XC tire. Rubena did a great job and you can safe a lot of money and you get top quality.

    Obviously the tread design is made for dry conditions and for more or less medium terrain. Good grip, even front (though I would prefer sthg. more grippy in front just to feel more safe while cornering).

    Weight: less than 500gr. Volume is absolutely 2.25, but the form is more round than usual, so someone might think itīs small.

    Superb quality, nice, stylish prints on the sidewalls, the carcass is flexible and itīs nice to touch the sidewalls. First impression when you touch it: this must be a fast tire. And it is one of the fastest tires for sure. My new favorite for XC riding.

    What are you talking about? Is it 2.25" (57mm.) wide or not?

    I've got an XC race next weekend and they're pretty much 50% of the weight of my Hans Dampf's so i've just pulled the plug and ordered some of these.

    Thanks for all the thoughts lads... you made my mind up.
    Where did you get them? Thx.

    Iīm sorry, but all questions about the tire size arenīt easy to answer and controversial discussed usually. Width depends on: kind of rim, pressure...

    I measure always the width of the uninstalled tire out of the box from bead core to bead core in cm. The Scylla in 2.25 is about 14cm like a 2.25 EVO- carcass from Schwalbe, so I think itīs all right.

    Yes, that's true. Given Francois' measurements for casing width on a 19mm internal width rim, I calculate a casing 'circumference' of 142.62mm. If mounted on a rim with an internal width of 25mm, this would yeild a casing width of 53.82mm (2.19") (and roughly a tread width of 53.32mm), at the same inflation pressure of Francois.

    To acheive a casing width of 57.15mm (2.25") one would need to mount the tire on a rim with an internal width of 34.1mm (using the same inflation pressure as Francois).

    But Francois' measurements were likely taken on a new tire. Bicycle tires will swell over time (usually around 2.5%), with most of the carcass growth occuring in the first 24 hours. Some manufacturing tolerances exist as well.

    Well then there you go, 14cm.! Unfortunately I've just trashed a Schwalbe Nobby Nic 2.25 so can't measure it. I have a Specialized Purgatory 2.2 off the wheel and just measured it, bead to bead, as being 148mm. The Purgatory is not as voluminous as the Nobby Nic.

    About 14cm in unused condition, as bholwell said, it will swell over time.

    The Scylla isnīt as voluminous as a Race King 2.2 SS for example. I know, some riders were gutted about this when they pumped up the tire and had a first view on it. But the carcass is absolutely state of the art and I realized a pretty nice "suspension effect" when I used it with low pressure. Low pressure wonīt be a problem.

    I think, itīs a great rear tire to be combined with a front tire that offers a little bit more aggressive tread design.

    You really need to make a page that displays all of the different models and shows tread patterns. The mfg website is horrible to navigate.
    The Rubena site actually shows each model's tread pattern, tire type, diameter, width and weight. I was able to find the relevant specs. If you have constructive feedback for Rubena website changes, you can offer it to Rubena (the MFG) via email or phone. Does that make sense?

    Looks like cadencecycleryDOTcom also carries Rubena, though you would need to contact them to negotiate a purchase. From the Rubena site, this was the only US distributor with a working site to state they carry Rubena...bike shops aren't the richest businesses though...I'm still looking for a Canadian dealer...

    @donnieboy

    According to the folks in CZ, there is a Canadian distributor but they really only focus on the urban tires and not the MTB tires. He did give me the ok to have you contact me about how to get a pair of their tires though. matt@cyclonebicycle.com Drop me a line and I'll see what I can do to help you out.
