Bontrager XR1 Team Issue

I just received a pair on Team Issue XR1 tires and I thought that I should share. The tires are intended for fast courses and tubes. There are two versions of the tire, a Team Issue and a Expert issue. The both have the same tread pattern but the Team issue has a softer rubber and thinner rubber. They have a claimed weight of 565g for the expert and 510g for the Team Issue.

My tires came in at 488g and 506g which made me very happy. There is now a tire option as light as a crow but with taller knobs.

Tubeless inflation on my 355 with yellow tape was not easy. It took 80psi form my portable 10 gal air tank, removal of the valve core and a lot of time. My difficulty was based on my past experience with Bontrager tires. Normally I can get Bontrager Tubeless and non-tubless tires to inflate with a floor pump. Any one with quality air compressor should have no problems.


They are labeled as 1.9" or 48/48 but are more like a 2.0 and take on a round profile when inflated. The look small when compared to my Karmas and ACX tires.

More to come once my flu bug goes away and I get a chance to rally them.
