    Bontrager 29 XDX TLR 1.75 tire opinion??

    I have been using the crossmark 2.1 and noticed the bontrager XDX TLR 1.75. I was thinking this might be a better race tire (only 1.75 less resistance), any comments?

    read up on offroad rolling resistance, narrower and/or more psi mean better rolling only on flat surfaces.

    why fatter tyres are faster

    good tire, right now bonty has the best race tires in my opinion with their latest crop of smaller tires. the geax barro race is the only tire to compete with bonty, wish some others would come out with 1.9's. how about a rocket ron based off the furious fred.

    The secret to mountain biking is pretty simple. The slower you go the more likely it is you'll crash.

    Contrary to popular opinion (mostly), I think the 29 X 1.75 makes a fine rear race tire on most terrain. I use mine thoughtout the year on both a geared hardtail and a singlespeed. I chose it because of the weight. No doubt it is low volume, but I like the way it rolls, I like its weight, and I trust it in rocky terrain as I find the sidewalls pretty strong. I does wear pretty quickly though. Airs up with Stan's and a pump period. No soap beads, compressor, etc and that is from new and on a Stan's ZTR 355 rim and a Bontrager TLR rim as well.
    Thanks to www.weavercycleworks.com for my awesome bike frames!

    The smaller tires make a 29er much more nimble handling and lowers the gear ratios as well. Notice the Fisher guys have won races on small tires and so did Ryan Treborn (on a Bonty XDX 1.75 in fact).

    Great race tire for the hundies with a lot of fire roads. I use them on my SF100, so the lower volume doesn't bother me too much. Casings are thick enough to be reliable on most terrain. It has enough tread to handle some wet conditions too.

    Those look like a good tire for my almost complete monstercross build.

    What's better for wet and mucky winter conditions? The XDX or the Jones ACX?
    I read that on the internet.

    My current favorite race tire combo: XDX 2.1 rear w/ a 29.3 Team Issue 2.25 front. Both roll really well and seem to give all the traction I need. 'Nary a burp, nor any other issues whatsoever.

    ...indeed...



    Rocked them for a few rides on the Superfly and they hooked up as well as the 2.1s that came on the bike.
    ...strictly downhill...

    can tell me someone if there is a big difference in volume between the 1,75" XDX and the 1,9" 29-0 ?
    think that could be a great front <-> rear combi for racing.

    i ride the 1,9" XDX at my race 26er and love this incredible fast tire. it is OK for almost all conditions, except deep mud (but at these day's i stay in bed and don't race ;-).
