IRC Boken Plus 650b Tubeless-Ready Gravel Tires

Traction & Speed on Any Surface

The Boken+ is a 650b multi-surface & gravel tire with a four part tread for smooth riding performance on any road. Boken+ tires are tubeless-ready, offering the flexibility to run with a tube or without. Running tubeless ready allows for lower pressures which provides better grip and faster rolling over rough surfaces, and a more comfortable ride.

The 650b size preserves the handling characteristics of your bike while giving you the tire volume to tackle any surface.
