I’ve run IRC tires for several years now and they have never let me down. I run the Boken Plus normally but opted to run straight Boken for Unbound 2024. The tires mounted perfectly and sealed without ever adding more air. The tires have just the right amount of bite for loose and dry and haven’t bogged down with mud. They spin up quick and feel great - smooth and fast. I’ve run IRC on road and gravel from 28mm - 47mm and would be hard to convince there’s a better tire. Well worth adding to any bike.
And PureGravel? They have ALWAYS gone out of their way to get orders right and shipped fast! Honestly, if I need to buy something I check to see if I can get it from PureGravel before I buy anywhere else. Thank you guys for being straight up awesome!
