Bontrager XR Tubeless Ready 29"er Tires: Out Of The Box

Twenty Nine Inches has just purchased a set of Bontrager XR 2.25″ Tubeless Ready 29″er tires to test and review. I have ridden quite a bit on the original XR’s that Bontrager introduced several years ago, but having these redesigned for their excellent Tubeless Ready system is something I was looking forward to. These tires just became available, so I thought I should give them the once over.

Of course, the Tubeless Ready version is also available as a front and rear specific tread pattern, just like the originals are. I opted to go with the front specific tread on both ends, since that has been found to be a speedier solution on our Mid-Western trails here.

XR tread pattern

The XR is listed as a “condition specific” tire design with a “front/rear specific” design. On the website, the standard issue XR is shown and is described as a “Fast rolling design that can be used on most trail conditions”. (Monster Cross Alert! The XR is also available in a 1.8″ version, non-tubeless ready) The weight of my two samples also varied in a similar manner to the Maxxis Ardent tires I just checked out. These weighed in at 670 grams and 730 grams. Claimed weight is 620 grams. Hmm…………perhaps a bit optimistic there, eh?

Tubeless Ready!

As mentioned, these XR’s are the Tubeless Ready version of this model and I am setting them up tubeless. Bontrager suggests using it’s own “Super Juice” sealant, and while Super Juice does indeed seal up the carcass of the tire quite well, it doesn’t do a whole lot for punctures. In light of this, I set my pair up with Stan’s sealant, which I have heard the pro team riders do as well. The tread is the familiar “arrow” shaped arrangement of trapezoidal, “L” shaped, and squared off stepped blocks with a “file” tread stripe on either side of center. The tires side knobs are a bit beefier and taller for cornering grip.

I will get in a few rides on these tires and report back in along with some measurements. Stay tuned!
