    Brand New Bontrager Jones XR TIRES!!!

    Got in the new Bonty Jones XR , "600g", folding bead, front & rear directional, like the Klaws/Smokes-not much of a paddle for the rear..
    The front is a "2.25" and the rear is a "2.20"we shall see after time flys by for them to stretch out.
    The tread is shallow compared to the ACX and dual compound "gumbi" rubber.

    Retail is about $35.

    My impressions:
    First off looking at them mounted it's going to be the "racin'" tire for your "racers"; Leadville, Brian Head, Cream Puff, etc.
    If you like the NOTOS or rolling resistance, you should lust these.
    The tread pattern is shallow enough that it should roll really fast, with the "gumbi" rubber compund it should corner well.
    The casing looks like it as flimsy as the ACX meaning us in the Rockies or sharp rock'd trails might want to wait until the jury is out on durability.

    We have been getting slammed with precipitation-snow and rain depending on the temps, so the riding here is reall good on Monarch Ski Area!!

    Happy New Rubber info to you all!!!

    You mean, a proper bike freak would get such hot tires in, and mount them to stretch before a weight check? ;-)
    Oh man, that sounds like the tire I'll be racing this year! Little knob, soft outer knobs, flimsy casing, that's a tire made for me!!
    If I get my hands on those soon enough, I may not have to put a powertool to my AcX's. Ofn the flip side, how am I ever going to finish my 2.15" Fast Fred frankentire with such an offering on it's way?

    $35 sounds like a fair price. Unlike $30 for a steel tire that first saw the light in '99.

    The XR has exactly the design we wanted to build. Weren't going for a
    super aggressive tread. Wanted good rolling with capable cornering
    knobs. Great all around tire.

    Sweet looking

    Very nice looking tire. Wonder if they have the same bead as the older Jones' tires? Or if it is a complete re-design? Probably the same.

    Those would be a fast rolling tire. Good to see more options coming online.

    Weight-schmeight........It's a freakin' 29" tire.........

    What are you gonna do about a "600g" tire that weighs 625gs? Blame Bontrager?

    Are you gonna brag about a tire that weighs 20g less and get everyone else bummed out since their tires weigh more?

    Tires do "grow" over time and the casing gets wider and taller, so yes I am going to wait to enable a "correct" measurement.

    That's the first tire I've seen that temps me to stray from THE TIRE.

    Are those now widely available at a LBS near me?

    Any Trek/Fisher 29" wheel supporting Local Bicycle Shop should be able to purchase them for you.

    We know it's bad, but technically it isn't Stan's that failed but the tire bead that fails. Hopefully the bead has been redesigned or sourced from another place, but I'm not going to be the one testing it this time.

    However, if someone wants to send me a set, I'd be happy to air them up (with googles, gloves, and ear protection on) and let them sit over night at 40 psi.

    Banks, do you already have some preliminary casing width number? Just the fact that hthe existing Jones is called 52-54, and the XR front is called 55/55, is so promising... If true, well worth the claimed 600g. Oh, I hardly dare ask...

    Technically, it wasn't Stan's or the bead that failed, it was a failure in judgement by the person who chose to use a product in a way it was not designed to be used.

    But heck, I'm just splitting hairs here...

    I could drive over and get a pair today (if Monarch's open) but wouldn't be able to use them for anything other than to look at for another 3 months.......so there.

    We've got some great snowpacked trails along the Northern CO right now (but melting fast.) Probably not the best tire for mud though, eh?

    So is guess you've never dropped off a 2 footer on an XC oriented frame. Better keep your bike on the ground if you're splitting hairs that way. If I busted a new XC frame doing something that is commonly endured by other XC rames, I'm going to let people know about it. Same analogy can go for tires.

    Yep,

    I know I'm getting the Ritchey's for next winter, and I might get those ignitors if they become available. I figure the more I buy, the more chance for newer tires. Plus, they'll all get worn out sooner or later ...

    Any idea why pics won't show for me?

    I'd love to see what the tread pattern looks like. Any idea how I can get something other than an empty box with "attached image" at the top?

    Hold down the control-key and click on the refresh button. Also make sure your browser has show-images enabled.

    Here is what my digi dial calipers say, all of the rims are Mavic Open Pro, since these tires are on display:
    WTB Motoraptor 48.3/52.6 Supposed to be a 2.1"
    Bonty Jones ACX 48.9/51.0 Supposed to be a 2.2"
    Bonty Jones XR f 49.9/53.2 Supposed to be a 2.25"
    Bonty Jones XR r 50.9/51.3 Supposed to be a 2.2"
    Schwalbe Little Albert 46.8/50.0 Supposed to be a 2.1"
    IRC Notos 51.5/52.0 Supposed to be a 2.1"

    Here is what is funny: 53.35mm=2.1"

    Front Bonty XR weighs in @ 660 GRAMS

    Rear Bonty XR weighs in @ 640 GRAMS

    Are you weight weenies happy now? See whay I did not want to "show off" weight?
    No, I am not weighing them all, so don't even ask.

    By the copy/paste method and they don't look too good for hard cornering...good for fast corners etc in dry conditions, but no good for wet MD trails and gravel...

    Thanks a lot banks, that's some very valuable info!
    That's just a bit unfortunate about the XR's weight, it partly compensates for the reduced rolling resistance. 1300g for a tire set, that's a long time ago for me, at least in a race.

    Funny how the Front XR 2.25" offers less volume than the 2.2 XR Rear. But, at even the rear is wider than the Jones 2.2", accounting for some of the extra weight. Jones' ewre closer to their claimed weight though.

    Interesting to see how wide your (recent?) Motoraptors are, that's a LOT of sideknobs. 3 years ago I managed to use a Moto in a Surly Cross-Check fork, rub-free...

    So, the third 29" tire that I ever knew of, the (discontinued?) Notos, is still the most volumous knobby tire for us. let's all cross our finger that Ritchey won't come up with a 52mm 2.4". WTB is coming up with a self-claimed 50mm 2.3"...

    I went from the NOTOS to the Jones ACX. I think that the NOTOS are way faster.

    I meant what I wrote, the Notos were the 3rd tire I ever heard of. After the Nano and the Moto. The Notos tread is not too slow, but I think the Bontrager carcass is a bit faster. Good they're still on the market.

    Did you get a spare pair, just in case? The weights, 660f/640r suggest it might not be as weak as the Jones.

    close. It's actually about 2 miles north...cross Mulberry/Timberline and my work is on the west side of the road just east of the airport. International Blvd is the closest road if you ride north on Timberline.

    Was that you on the green Karate Monkey on the bike path the other morning? I was riding a silver IF 29"er.

    Yeah, that was me monday morning. I was cutting through the little field to test the mud for frozenness. It was indeed good and frozen but when I got up to the hogbacks it wasn't - temperature inversion. Peeps, dogs, and horses had really tracked out the trails on Sunday when it was good and gooey. Amazing that the trails recover from that kind of damage. Makes you realize that a lot of the admonitions against riding wet trails are overblown. Somehow the trails bounce back if they don't lose too much soil..

    Anyway, pine ridge OS was fine and frozen but coming down maxwell after climbing the road was an aweful mess. I should have just come back down the road. I might have to stick to the gravel ponds off e. prospect or the powerline trail south to trilby. At least when it snows you get a bit of resistance and a little workout.

    I thought your bike looked a little "tall." Small world, eh? I think I saw your wheels up at the Laramie enduro too. I've got a ways to go before I'm in that kind of shape again!

    Got mine today

    They look/feel/weigh pretty much the way that the manufacturer described them--a solid all around tire that strikes a good compromise between weight, cornering, and rolling. Mine weigh 645/654, and are precisely one mm wider (casing) than the Notos or Mythos. Nice looking tire. From my perspective this'll be a great xc tire. Not the lightest, but who would expect it to be?

    Tubeless freaks beware--the sidewall says something about an 'aramid bead', which was the physical point of failure on the Jones, right...?

    Seems (from some of the comments above) that our expectations are a bit high. We (collectively) are clamoring for fatter, lighter, and tubelessable, all at once. No wonder we're getting none of the above--the manufacturers are starting to snicker and call us 'Sybil'...

    For my uses, the tread and casing on this tire will be good for general use. That means for use when I'm not racing, not worried about weight, and not trying to run without tubes. In short--general trail riding. They're only one mm wider than anything else, but it is a start...

    MC

    P.S. Thanks to Banks and the gang at Absolute Bikes in Salida for the lightning fast delivery--I'll be riding them this weekend.

    Thanks Mike, so for you at least it's already a bit wider than the Notos. That's great, my single Notos looks huge compared to the other knobbies.
    If the XR offers lower rolling resistance on top of that nice volume, I'll already be pretty happy. All I have to race now is one steel Nano and that trusted Notos.

    In asking for tires that have it all (I may be quilty as charged), don't forget that riders often also state they'll pay good money if it's actually offered. This XR is $5 a piece cheaper than the Jones. The Jones was already really cheap in Europe, €26, but I gladly paid $40 when I could only get them from Speedgoat.
    There's plenty 26" offerings that offer super-low rolling resistance, beads that hold, at a low weight for the width.

    Should Bontrager manage to make a $45 version that is similar in weight but as reliable when it comes to latex job, like all IRC's and Kenda's, for sure it will see demand.
    As long as IRC and Kenda don't come with race tirs, I'll just eat the weight, use latex tubes and race the XR's, I'd be surprised if they wouldn't be faster than a steel Nano/Jones combo. Or perhaps the Maxxis Ignitor will prove a good front.

    Can't wait to try all new stuff!

    Tubeless 29 Bontrager

    I want to communicate to everyone that Bontrager does not recommend using Stans or similar products on our 29" Aramid bead tires. Our experience has been that the bead will blow off more frequently then not. You will likely be dissapointed with the results, so I'd rather be clear up front that this tire should be ridden with a tube. This isn't a knock against our tires, because we built them to be used with a tube.

    Nat Ross and Cameron Chambers have both spent a lot of energy working with Stans. They find that for 29" a wire bead IRC tire is their most reliable option.

    We are gradually working towards more standardization for 29", but for right now there is enough variance lead us to recommend against Stans.

    Cool...Were you driving a VW up at the Enduro? That is a pretty sweet race and i'm planning to do it again next year.

    shoot me an email offline if you wanna ride sometime...I live 3/4 mile from pineridge/dog park on west Horsetooth and ride that a lot.

    What wire bead IRC's would that be?? I know of any.

    I also never heard of wire IRC's, the folding beads they use just seem to hold just fine.

    Weight

    I just weighed my new Jones XRs. 615 front, 645 rear, tared and reweighed. I must have gotten the racing version! Or maybe just missed out on the extra-mileage version. I'll make sure nobody left off any knobs!

    I'll buy that front from you for $5 over MSRP. Lightest grams I'll ever invest in... ;-)

    So okay, these seem to be slightly bigger than any knobby we've ever had. Anyone ride them yet?

    I rode mine today and I love them! Nice and cushy, good grip, and corner very well. I think I like these more than Nanos but I'm not quite because I just switched from a set of Mythos.... which are horrible (my opinion). IRC needs to make some 2.25 and 2.5 Trailbears in 29!

    I know other French that ride 29"ers, well at least one, and he actually rode his bike, you haven't even built it, in the months you've owned it. I wish you guys were as patient on a narrow mountain road ;-)

    ouch !

    Yes, you are right, it's not buid yet
    But it's comming, i ordered the missing parts 2 days ago.
    I must say that i'm reluctant to try it with the skinny tires i have, to close to a road bike.. That's why i need bigger tires !

    I do know another french KM rider in Bretagne. Where is yours ?

    PS:
    With all the snow that falled yesterday, my ski are yelling far louder than the km to get out...

    Get a "sike" frontwheel-to-ski conversion and make your first KM ride a snow descend...hmmm...I wish we had snow.

    I believe his name was Claude Moinier, living in Holland for a long time already, he built up the first-year SuperCal29 in M, loved it. Haven't seen him around for years.

    Back to the tires, the "stepped" knobs look really modern and FAST to me! I can't stop looking at the above pic, it's just sexy all by itself.

    I too have never heard of such a tire from IRC (ie, a wire bead). I spent some time at one of races last summer and actually spoke with Cameron Chambers. We talked about what works and what does not work when it comes to tubeless. He has spent a lot of time trying to figure this whole thing out. It came down to 2 tires that worked for him...the IRC Mythos and Notos. He never mentioned anything about them being a wire bead. Granted, that was last summer and things could have changed between now and than. I on the other hand have had great success with my Bonti Race rims and AC rims when running them tubeless with the Notos and Mythos tires.

    Also, I am not trying to convince anyone of going tubeless. You need to see what option works best for you in your area of the country or world. If something fails, by all means don't blame the manufacturer because WE SHOULD ALL KNOW THAT TUBELESS DOES NOT WORK FOR EVERY APPLICATION. Use caution and be safe! Bontrager does make some good stuff and I am very optimistic about what is to come.

    BTW, Cameron sure is a great down to earth guy. He was really cool when we shot the breeze about bike stuff.

    No you don't!!! After a very short while, all you can dream of is dryish conditions, not having to cover every corner of skin, and being able to ride for more than an hour without worrying about frost bite!
    MTBR is serious stuff.

    It's been pouring with rain all afternoon now, I have no overshoes with me today, ride home is 17km over mostly tarmac cyclepaths that keep that nice filter of water on them, even after a shower, so you get soaking wet anyway.
    I'll take snow over rain every day, even if I have to do it on slicks.

    Didn't get the guy on the line, had lunch meeting when he had time. He sms't me €26, not sure that's the AcX (very cheap in the EU, for some reason) or the XR. Availability no answer. You can always just call Trek directly. I refuse to, since the way I was treated when I first asked about the AcX Jones.

    Bump, it's really time for some good reviews on this XR, surely not the whole world is covered in snow now?

    Trek Europe is in Holland. I guess my LBS just got them with their next weekly shipment or something. For France, allow an extra week for shipping, I'd say.
    Why did you only now order tires for your otherwise complete bike?? ;-)

    Quick and unedited, but long review :

    The XR tires are very nice. Mounting them to Dyad takes some extra caution, the fit loosely. On a rim, they just look dead-sexy.

    I just came back from a short ride over local, really lame trails and anything non-pavement I could find to ride. I rode my rigid surly Karate Monkey.

    Unfortunately there was no real hardpack to be ridden, at least not with corners. In thick mud it shedded very well, and drifted pretty much predictedly. No mud tire for sure, but some mud in a race will not ruin my day at least. In deep sand (construction site in front of my house), it actually handled pretty good, at least as good as the Nano, and almost as good as a 2.35" Fast Fred.

    Off-camber grass was handled well, trashed grass strips didn't really ancor the the bike too much, it more or less hovered over that stuff.

    Rolling resistance was hard to rate, especially being on my singlespeed Karate Monkey, but seemed to be good, considering it's offroad capacities.

    Perhaps not as fast as 2 Nano's, but definately not much slower than a rear Nano and front Jones AcX. In the tacky stuff, I got the impression that the stepped knobs slower me down less than with a full-knob like the AcX or my previous favorite, the Schwalbe Jimmy 2.1. a Maxxis Minotaur in 2.1" would be even better for today's conditions, but since the excellent 26x1.9" is out of production, I'm affraid a 29x2.1" will never happen :-( The 1.9 was the best grass and semi-mud tire I ever had.

    The front XR seemed to require lower pressures than the rear, but I should note that the front tube used was a pretty thick but narrow Hutchinson 26" tube, and the rear a very smooth, already stretched 26" Geax. The rear seemed to roll and squirm a bit on pavement corners where I threw my eight in it. Perhaps it needs it's full 2+ bar, as the front seemed to be pretty harsh even at 2 bar, and might be best ridden at under 2 bar. The rear at 2 bar felt on the limit of being too low already. I did ride these trails for 2 weeks, but then with a Nano front they seemed less bumpy. Not sure how my 3 hours of pavement yesterday influenced my observations today.

    I rode by myself, trails were tricky wet to really muddy, so I didn't really dare push the limits, but the front really rarely stepped out, where the rear for sure was trying most of the time.

    Braking traction for the front tire on just-not-dry hardpack was very impressive, the rear was not too hard to get to skid, but did get me up the occasional steep dyke (dijk).

    Overall, the way the XR's handled in non-hardpack conditions, gave me good confidence for it's hardpack performance. The feel big and suptle, a nice experience.

    Already before getting them, I though that the front looked to have a faster rolling tread pattern. Difference will probably be really minute, but after feeling how the front seemed to corner better than the rear, I more than before feel that riding with 2 front tires is worth trying. The little extra cush for the wider front, without the weight penalty, can't hurt either.

    On this first tstride, the front XR impressed me much more than the rear did. The rear deserves a next chance in try dusty hardpack conditions, but right now I can't imagine a front/front combo to work out really bad. Only comfort of the front seemed a little less, but that could well be just my perception.

    Hope any of this made any sense at all,

    Hope you don't have a bad monday,

    J(an Gerrit)

    Edit : just to confirm : LBS set retail for the XR's to €25,60 each, including VAT. Very good value for such a tire!

Where I ride (typically very dry) I think they are slow rolling compared to my Jones-ACX, IRC-Noto and IRC-Mythos, but they hookup in corners extremely well (scary in fact). The sticky rubber picks up everything and throws it up in dry conditions, but in moist stuff there is no problem with this. It would be nice to hear from someone who has used them in wet root/rocks areas. I would use these any where I really wanted some good traction and I will continue to use them as an all-day epic sort of tire. One more thing - these tires fit very tight on my Bonti rims (unlike the super sloppy fit of the ACX). The tight fit has me thinking I may try to run them tubeless (with extreme caution of course). Yeah, yeah I can hear you all now saying don't do it....

    Interesting, I also have a pair of XR's and find them much faster rolling than my ACX's (opposite of your perception).

    Iran the XR's at Harmonic ConvergenSS, which had hundreds (thousands?) of slippery roots. I had some trouble with traction on a few steep, sorta muddy pitches, but didn't notice anything on the roots. Maybe that's good?

    i like em

    i've been running the xr's for 2 weeks. got them thru my old shop. seems close in cushyness to the epic wolf but without the weight. they are obviously not as fast as the nanos but more grippy and a more cushy. they make my acx's feel much slower.

    Yeah, I suspected that the XR may be better in a different terrain than what I am riding most of the time. Heck we've only had a half inch of precip so far this year so things are a tad dry to say the least. I rode some areas along a creek bottom this last weekend that are usually at least damp, but instead found it mostly dry. Also, I rarely see anything with slippery roots unless I make a long trip over to the Cascades. So for now in the dusty hell where I have ridden, the XRs are just not the best ticket IMO. But I have faith that they will be superior for others and I think they are an excellent tire.

    Stella was the driest I've seen it on Saturday. The roots get a whole lot slipperier (?) than that. I ran the Jones ACX there just after getting my KM, and hated it. No idea how the XR would do.

    Man, I'd forgotten about that. Now you've got me drooling just thinking about it ... leftovers from the previous night's feast at Delta Cafe ... BBQ chicken w/ Delta Red sauce, potato cheese casserole, and red beans 'n rice. Nice.

    I have barely tested the rear XR, just in mud and snow. Now run a heavy wire tread Nano rear and XR front. I don't notice the front tire to be slow, I used to often run Nano rear, but with an AcX front. The tire is harsh till you drop it under 2 bar. That's also when it starts to generate grip, and then it a pretty good tire. Not grippier than the AcX as far as I can tell, but it seems more as ease on pavement, less knob roll. I'm looking at voiding the warranty on a whole bunch of tire, putting the power belt sander to it. 29" tires are just to masculin for my race queer ass :-)

    Just came back from my first real MTB ride on the XR.
    I'm very pleased with the grip. They for sure are slow rolling on the pavment, but the give a lot of grip on the trails.

    Good lord, am I the only one who thinks they roll fast on pavement?

    Today on some pretty technical, ultra-twisted, but oh-so-smooth trails, I swapped bikes with my buddy a number of times. His VooDoo was on 26x2.4 Racing Ralph rear, 26x2.35" Fast Fred front. Absolutely definately faster rolling, pretty significant different. I can only dream how those tires in a plus size would perform. His bike was 26"-sketchy, but gripped just fine. Tires were 500+600g, which translates to 550+660+1150g in 29". My much narrowed XR's are around 1300g for the set. Grips was too big to really explore the limits safely on the available trails. Overkill. Lots of fun though, time of my life, 1x9 setup on the KM, though the trail was very well SS-able. Did it all in 44-21 on the VooDoo as I had my hands full not to crash.

    The XR are wide, use a slow rebound coumpound, and do not have continuous knobs on the center. They just can't be fast rolling on a hard surface !

    For a hard surface, the continuous knobs + little size + hard coumpound of my mutanoraptors all help to make a huge difference !

    This said, if you ride over a soft surface, than a big tire can have a lower rolling resistance, thus you can feel your XR rolling fast.

    All theory aside, they feel fast to me.

    Probably a 29" thing, you're just enjoying every wheel rotation of it, and have probably not tried Nano's yet. The XR's feel just fine to me, but swapping to the VooDoo made a big difference. On slight downslopes I could coast to keep up my 15kg heavier buddy, pedaling the KM. He prefers the KM though, only problem is to explain to his wife that one bike is just, one bike, and they need new company once in a while.

    I haven't tried the Nanos, but I have tried the ACX's. The ACX's feel much slower, both on and off dirt.

    bought a pair of the new XR's today for my sugar build, and top secret new wheels...they seem light, and look fast...still need some drivetrain parts to complete the build before I'll really know though...
