    Maxxis Aspen

    Since it was displayed at eurobike and mentioned in another thread by the engineer I thought it might be ok to talk about this tire a little.

    I rode the 2.25 version most of the summer on my 5 Spot and loved nearly every minute. It rules the hardpack. Sooooo freakin fast! Even with the minimal tread pattern it corners and brakes well.

    Now what I want is a 29'r version of the 2.25!!!!!!!!!! Are you listening Maxxis?

    Aspens Specs & Info








    The Aspen 26x2.25 is still in the testing / development phase, and so the specs have not been finalized. Here are a few photos- it's a large tire.







    I won't be posting any rider evaluations of the tire, but expect Geoff Kabush and Mathieu Toulouse to be riding it quite a bit next year.

    Just when I had settled down with my tire choices, you pull this!

    Looks like a really nice rear tire to match with an Ardent front.

    Would the 2.25 version be a 60tpi and ~600-650g? (I would actually prefer 700g for more sidewall )

    Also is the 62a the Maxxpro compound? or another?

    Thanks for bringing a fast roller to a larger size.

    Here in the UK we have mixture of conditions, one day its dry, next wet and muddy. The trails in Wales have a real mixture of rock gardens to roots and mud to hard pack in the same trail so it makes it really hard to pick one tire. I am currently running 2.1 Nevegals and am pretty happy just fancy trying something different! What do you think is the best Maxxis all rounder?

    Thanks for you help..

    It's a bit tough to recommend tires for trails I've never ridden; usually the best advice is to observe what others in your area are riding. Having said that, take a look at the Ardent 2.25 front, and the ADvantage rear.

    Sorry if this has been asked previously, but...
    Approximately when can we expect to see this tire for sale in the 26" x 2.35?
    Thanks!

    Hmm, i like how that tread pattern looks.
    When under pressure, your level of performance will sink to your level of preparation.

    Hi bholwell,

    I kinda took your advise, ended up with a 2.4 Ardent front and a 2.25 Ardent rear. Now its starting to dry up a little here I was looking at the Aspen as a rear tyre!

    When will these be out in the UK, I see they are for sale in Germany!

    Cheers

    Any ideas about the weight? When they want to make a fast roller hardpack tire (racing tire), it should have racing weight...
    If You want Plush, Buy a Couch...

    Apparently these tires are already available in Europe. Does anyone know how I can get a set? I have found a company called Silberfische.net, I think a German company, has them for sale but I have not bought anything overseas. A local company contacted Maxxis who told him that is was up to the Destributor for the U.S. whom decides when certain tires and types ie Different durometers of tires are released and where. Case in point, a person in Europe can get a Maxxis Larson TT Downhill spec. casing but you cannot get one here.
    Anyway I just would like to try this tire for a race coming up soon.
    Thanks,

    Did some prototype testing for the Aspen, 2.25 and 2.1. My favorite tire! I run the 2.25 on the front and 2.1 on the rear, and it's an amazingly fast yet controllable combination. Can't wait for them to be available for sale, because I've worn out all my test subjects

    What type of riding were you using them for and how were they in the wet??

    For 90% of my riding I run a Aspen 2.1 or 2.25 on the rear, and an Ardent 2.25 or Aspen 2.25 on the front. The Aspen performs surprisingly well in wet conditions, as long as it's not too deep or isn't the peanut butter GA red clay we have in the South (nothing does well in that stuff, though). The relatively open tread sheds mud pretty well.

    They do pretty well in the mud, I was kind of surprised. I have never used them in front range CO mud, because our mud is cement in disguise and I'm not of fan of wrecking trails, but I did get the chance to use both the 2.1 and 2.25 in Vermont for a short while, including nationals last year. The stick very well to wet roots and rocks, and as long as the mud isn't super deep you are good to go. They shed everything off super fast once you get back on dry land. Treads are open and low, like bholwell said, so nothing stays on there.

    On my hardtail running 2.25 front and rear was great, because it's such a high volume tire. For the FS the 2.1 is plenty squishy for the rear end. Weight is pretty good as well, and they go tubeless easily in my experience, even with ghetto tape/homemade sealant. I really can't wait for them to be for sale! I can't think of anything I would rather run for racing in Colorado.

    Any chance they will be available in a 650b?

    Last year the rumor was Kenda and Maxxis were going to make 650b tires; so far we only have a Nevegal. I'd love to put a Ardent on the front w/ a Aspen on the back...

    So I answered my own question, found a site that was selling them in the UK. They only had the 2.1. I have mounted it on a Shimano 08XT wheel at 40psi. I guess this may stretch a little so will let you know in a few days. Pics tell the story, at the moment its coming up a touch small! Tread looks great though..

    Not really. The prototypes measured roughly 2.06" at the casing, and 2.11" at the tread at 65 psi. The casing will stretch over the next couple of weeks, though.

    I'm glad you like the tread. You can clearly notice the two different tread compounds in your pic. Now go get it dirty!

    GBR, I ride the same places as you, cut off every other transition knob on your nevegals, it massively improves the tyre for uk conditions.
    It reduces rolling resistance, increases traction on sandy trails and most importantly stops the tyre clogging with mud.

    trust me on this, huge improvment.

    Thanks for the info. I no longer have the Nev's, I now run the Ardents in Wales, much better IMO than the Nev, better grip/traction and less rolling resistance!

    I was looking at the ardents, might try one when I get through my box of Nevs (bulk order from unicycle.co.uk, really good prices for 29er stuff)

    Maxxis (as do other bicycle part manufacturers) generally showcases new products at Eurobike and Interbike in September, so be on the lookout for them then.

    Now guys, don't ask me any more questions you know I can't answer!

    I inflated the tyre to 65PSI over night and then went for a ride today as the weather was great, it happens 2/3 times a year here in the UK

    I measured when I got back and sure enough it was up to 2.1, so there you go!

    The ride was great, just a local ride so a real mixture of gravel tracks, grass, hard and wet mud. Too early to tell too much but so far so good, its definitely fast!!!

    For your info I ran it with a 2.25 Ardent up front on my hardtail, I think this will be my combo for the year!

    Wondering if you have run the aspen's with Stans?? I picked up a 2.25 today and think I may run it on the back of my Mojo, the side walls seem fairly thin, probably a touch thinner than the Ardent it may replace..

    Thanks for the help..

    Works well with Stans goop on Stan's rims. Not sure about other rims.

    Yes, the casing of both the Aspen 2.1 and 2.25 are 120 tpi, while the Ardent 2.25 has a 60 tpi casing.

    I saw Kabush racing them.

    It looks like a great tire, I just hope they will release it SOON!

    I have been using some Aspen 2.1s converted with Stans for the past month or so. Rode a couple of stages of the BC bike race with them and have done pretty rugged trails and they have held up well.

    A UST version would be great.

    Verrrry interesting.

    I'll be submitting an application for sponsorship to Maxxis this fall, that's for sure.

    I've been running a pair for several months and I don't see any similarities to the Rubena. The Aspen is a FANTASTIC lightweight racing tire, and have proven to be very durable as well.

    Are you implying that Maxxis is copying Rubena's tread designs?

    The Aspen 26x2.1, 26x2.25, and 29x2.1 were released at Interbike last week, along with the Ardent 29x2.4, the MudWrestler 700x35C CX tire, and the Radiale 700x23C and 22C road tires. Check the website - www.maxxis.com

    They're on the water right now, and should arrive in a few weeks.

    Sweet, thanks for the super quick reply. I'm picking up a set of the aspen exceptions as soon as they hit the distros.

    I would've like a larger 29er, this looks like it would excel so much more as a front vs a rear plus I am a heavier guy and prefer a wider tire.

    Anyone see if GT had a write up on these yet?

    Got the tires mounted up on friday, they look nice inflated. We just got a crazy amount of rain here today, so I won't be testing them for a few days. I weighed them before I put them on, 460 and 461g, super light. The sidewalls seem a bit thinner than the crossmark exceptions they are replacing, but they aren't as thin as a schwalbe evo or conti SS.

    I was thinking about trying the aspen 2.25 as my rear tire. I ride in NC. Currently I have a Maxxis Crossmark 2.1 as my rear tire. Does anyone know how these compare to each other in terms of rolling resistance, cornering traction and stopping power. The Crossmarks are fast but I was looking for a higher volume tire. Thanks.

    I would say the Aspen 2.25 has comparable rolling resistance and braking traction, and better cornering traction and climbing traction than the CM 2.1. I think it will suit your needs.

    I don't have the time to write a full review, but I will say that these are probably my favorite tires yet. They remind me of a cross between monorails and crossmarks. There is a lot more grip than you would think by looking at them. I went out for my benchmark 17mile loop at my local trails, which are very rooty, mostly twisty, narrow singletrack, with some paved bike paths, smooth doubletrack, and about 1mile of road thrown in the middle. The trails have received quite the soaking of rain over the past two weeks, but I let them dry out enough to not feel guilty about rutting them up. The combination of wet leaves covering basically every trail, with hidden patches of deep slippery mud made for a n eyes wide open ride. You were constantly trudging through either soft dirt or thick leaves, putting extra effort in to go a normal speed and then all of a sudden you would hit a turn and instantly start sliding from the leaves. In these sketchy turns, the aspens provided a progressive slide before the side knobs hit and dug in. Much like the crossmarks react in a turn. On the roots, you could feel the center knobs actually grabbing and pushing the bike forward. On the smoother parts of trail and the paved sections of the ride especially, you could really appreciate the low, low rolling resistance and round overall tire profile. The one thing I was particularly impressed with was the tires mud shedding ability. There are a couple of low lying sections of trail that were quite muddy. There was one section that had that kind of quicksand like mud where your single objective is to keep the bike moving forward, even if it is at 4 or 5mph, so that you dont get stuck. When I got out of the muck and back onto terra firma, the tires were cleared completely out after no more than 30 feet of riding on solid trail. That is a nice change from the crossmarks that like to hold onto mud and spray it all over your face for a mile before they clear out. The icing on the cake for these tires are that they sealed up instantly with stans (I know, I know) and they are incredibly light, over 120g savings over the crossmarks. There are a few XC races I am looking forward to using these tires next season, I just wish I had these in the summer, with hardpack, where I am sure these tires would shine ever more than they have already.

    Has anyone managed to mount the 29x2.1 on Arch rims without a compressor? I've used crossmarks, ardents and rampages before only needing my floor pump to inflate them.
    My normal method is to inflate with a tube, unseal one bead to remove the tube, work the bead back into place and then inflate. The problem I'm having with the Aspens is I just can't get the second bead into place.

    Any notes about the any flats people who set them up tubeless? Just would like to know if they are pretty durable as they are not tubeless tires or tubeless ready, but do they hold up good and everything tubeless?

    I have a pair setup tubeless on Crossmax SLR's. No problem mounting them and I've had no flats. I've ridden them in some extremely rocky conditions that have shredded other tires and they've held up really well.

    I think they went pretty conservative with the advertised weight (475g), so your chances of getting one lighter than that are pretty good.

    2 rides, 120 miles on my Aspens now. Fast, good traction for what they are. But they don't seem to be holding the air tubeless, they got very soft towards the end of a 6 hour endurance race yesterday. I need to try and find where they might be leaking if I was to use them for any longer races.

    ho do you mount the aspen in the rear?
    If I mount it like in the front, for better rolling, will it have enough traction in technical uphills?

    thanks

    I would mount it in the indicated direction- I don't think you'll gain much climbing traction by reversing it. I think you'll be pleasantly surprised by the traction, though.

    how would they compare vs. Race Kings? My only complaint re the Race Kings (2.2) is they can be sketchy through corners in loose over hardback. Seems like the Aspen might hold better with the side knobs?

    Aspen 2.1 Exception

    Purchased a Aspen 2.1 Xception recently and set it up as tubless (30psi) on a Stans 355 rim with rim tape only (ie. no rim strip)

    Tyre weighs a true 445g and would seem only a mm or so off being a fullbag 2.1 like the Advantage Xception 2.1.

    It's easy to see how there's such a difference in weight compared to the Advantage Xception 2.1 (526g) as the tread depth/side knob height is at least half, if not 1/3 of the tread compared to the Advantage, but.....this means that the Aspen rolls heaps better on any dry terrain.

    Although the packaging says it's a XC tyre, trailriders in dry climates will find that it's a great rear tyre. I expect though that when it's wet you'd have to manage the lack of traction, also this would apply after you've logged a few hundred miles (terrain pending.

    Well, I'm pretty happy with the Aspen other than Maxxis producing an Ardent 2.1 Xception looks like I've found a true 2.1 fast rolling rear tyre........

    the maxxis website lists the Aspen 2.25 (TB72557500) as 60tpi (and heavy at 695 grams) and it appears the only 120tpi online for sale is the 2.1 - does that mean the 2.25 120tpi Aspen is not available in the US market?

    Correct. The decision was made to only bring in the 2.25 model in a 60 tpi casing.

    Mounted a 2.1 Exception tire to my rear DT Swiss 4.2d last night... bead set really easily however....after putting some stans fluid in and letting it sit over night they where down to about 20psi... got some soapy water and sprayed the tire to see where the leaks where coming from and comes to find out it is coming through the sidewalls of the tire....

    Ive never seen a tire leak so much air through the side wall as i usually get some leaks where the bead is.... I am hoping it will seal itself up so i can give em a good ride.

    This tire is great. I've never had a tire that rolled so fast, and accelerate so easily. That being said I just tore through my sidewall on my front tire yesterday, (I was rideing pretty aggressively). I don't think I will be using this tire on the front anymore, probably stick with a highroller. Extra traction on the front tire can't be a bad thing.

    I'm betting that won't improve with wear.

    Exceptions are pretty thin in the sidewall - my rear Monorail Exception is looking a bit threadbare on the sidewall for it's young age, and has been a cut a couple of times. I can see the carcass threads through the thin top coat of rubber.

    Great tyres if there are no sharp rocks around, but they get cut up too easy around here, as do most light tyres .

    2.1 or 2.25 size?

    I'd really like to try out the Aspen, but I'm not sure whether I should go for the 2.1 or 2.25 size. I've had the Geax Mezcals 2.1 for some time. A good tire, but it lacked some grip in the front at times.

    The conditions I'd like to use the Aspen for are mostly dry, on trails with hard mud and with some roots. There are hardly any uphill or downhill sections here.

    Perhaps a 2.25 on the front and a 2.1 on the back?

    Still haven't decided on 2.25 or 2.1. According to Maxxis.com, the weight difference between the two is 220g, which is quite much if you ask me.

    The trails I ride, have a lot of corners and some roots. Perhaps the 2.25 might be more suitable, but I'm slightly concerned about the weight.

    I run the aspens tubeless with 3 scoops of stans solution on my 29er, so far the rear is holding up the air and the front is a working progress. Im still shaking and turning inthe last 4 days now.

    with these stubborn cases it often helps to deviate from standard procedure: simply put the wheel flat on the floor. It's now tilted, e.g. only a small part of the tire touches the floor. This is where all the sealant is now. Leave it there for any time but at least a few minutes. Then work your way around the tire always leaving the presently floor-touching section sit for a few minutes (or longer). Do the other side.

    Laying out the wheel on a box is often not sufficient since it's never really flat and there is too little sealant to cover the entire sidewall around the entire wheel (which of course depends on the tire size). For some micro-leaks it simply takes some time to penetrate the sidewall, I mean, in the end it's just some porous material.

    I agree with Mr Holwell on this one. I have been switching back and forth between the two lately. The aspen rolls really fast, you can tell by how quiet it is on pavement. The crossmark and aspen are extremely similar in terms of absolute cornering grip. You have to lean into them both, but I haven't found the aspen to be any worse. Where the crossmarks shine compared to the aspens is in sloppy conditions, as the crossmarks track alot straighter, and in loose over hard, like leaves over rocks, as the aspen simply doesnt have enough tread depth to cut through onto the grippy part of the trail.

    I loved my Aspens. They were definitely the fastest tires that I ever put on my mountain bike. I never had any traction problems with my Aspens that I didn't have with my High Rollers, (once I learned that you had to lean the bike over). The problem with them was the sidewall. I went through the sidewall of my front and rear pair in 1 month. I guess when they say race tire they mean it. Unfortunately I cannot afford to buy a set of tires every month, but if I do begin racing I am running these.

    The conditions I'd like to use the Aspen for are mostly dry, on trails with hard mud and with some roots. There are hardly any uphill or downhill sections here.

    Perhaps a 2.25 on the front and a 2.1 on the back?

    Try thr Geax Segauro 2.2 .Better corner grip and faster than an ardent and possibly an aspen?

    It's been a while, but if I remember, my exceptions were around 460g each. I hope to be putting them back on soon now that we are getting into normal trail conditions here and I will re-weigh them.

    In general some more ride-reports.

    And hoping somebody could compare them to a Continental RaceKing 2.2 Supersonic,
    my favorite tire, but with one downside.
    They have very thin sidewalls, I already cut 2 on some rocky downhills.
    If i read some reports en specs. off the Aspen here, it can be a good replacement.
    So, in short...Can you compare those tires ? Or somebody else ?

    When is the UST version being released? This is a super fast, light, and grippy tire. My only complaint is that I could not reliably run them tubeless. Thanks!
