Faster, better cornering version of the proven original XR1 29er. Intended for fast hardpack or loamy conditions. Developed in conjunction with professional race teams. Covered by Bontrager's Unconditional Performance Guarantee. Available in 2.00 or 2.20, aramid bead, 120 TPI.
Bontrager has really improved their tires. This 29-1 really corners well and rolls fast. Perfect for xc racing. I haven't had it in mud, but that's not their intended use any way. I used the 2.1 in the rear. I want to try the 2.2 up front next. I'll report back.
Strengths: Great tread pattern for hard tacky trails, which is what I ride mostly. Sidewall seems to be pretty strong as I have ridden some pretty rocky trails and have had no problems.
Weaknesses: None so far.
If you are riding soft or even muddy trails you probably won't like this tire.

I was wondering if anyone else is runnin ... Read More »

Just bought one to try on the rear . rolling resistance seems low for the size and knobs on the tire . garyfisher ... Read More »
