Fast & grippy!
Does hold onto mud a little more than desired.

My Fav

After riding about 300 miles on these tires after receiving them a couple weeks ago, I can undoubtedly say these are my favorite gravel tires ever. They give me confidence on sketchy descents (I've had a few PRs on some descents since rolling on them), feel good on climbs, and are fast on pavement. I was impressed by how quickly my order was processed and shipped out. IRC had me rolling on my favorite new tires quickly.

Great Tires

After learning about these tires at Gravel UnBound camp a pair was ordered. Shipping was fast and the product is as described. Looking forward to using these at the race in a few weeks.

The best tires I've been on

I was preparing for the UT Belgian Waffle ride and took advantage of IRC's sponsorship and advice and bought a set of IRC Boken tires. An unforeseen circumstances prevented me from going to UT but I rode Strada Bellmay in North Florida which was a 135 mile gravel event. The conditions were packed gravel, sand, loose gravel, pavement and some pretty rough roads. The Boken's were perfect in all conditions. They were fast on pavement, but secure when things got loose. I often look at gravel tires as what trade off do I want to optimize for but I have now found the perfect goldilocks tire!! Love them.
