When you’re in the dirt, the type of tire you use has a huge impact on your ride quality and performance. Gravel and looser conditions will require more grip than riding on hardpack surfaces. The IRC Boken Plus Tires are built to provide exceptional grip for serious gravel riding. The Boken features a shallower diamond tread in the center that is perfect for riding on smoother surfaces and hardpack dirt, while the deeper side knobs offer increased traction and control in softer terrain. The ultra-gummy compound gives riders insane bite on those tougher obstacles, so you can ride with confidence. This tire is a great balance between a fast-rolling tire and a super-grippy tire, so you can have the best of both worlds.
