IRC Boken Plus TLR Multi-Surface Gravel Tyre - 650B x 42
The IRC Boken Plus TLR is a tubeless-ready multi-surface gravel tyre designed for riders who want a comfortable, capable, and versatile option for mixed road and gravel riding. In the 650B x 42 size, it offers a high-volume setup that provides extra comfort and grip compared with narrower tyres while maintaining a responsive ride feel.
IRC describe the Boken Plus 650 as a multi-surface tyre with a four-part tread design for smooth riding performance across varied road surfaces. It is well suited to tarmac, hardpack, rough roads, light gravel, wet road conditions, and mixed-surface adventure riding where comfort, speed, and grip all matter.
The tread design uses a smooth centre section to help maintain speed on tarmac and firmer surfaces. An inverted micro-diamond pattern is designed to assist with wet traction, while hollow-centre tread blocks allow the tyre to flex and grip when the surface becomes rougher or less predictable.
The 650B x 42 size gives riders a comfortable and capable option for gravel and adventure bikes with compatible clearance. Tubeless-ready construction allows the tyre to be run with a tube or set up tubeless on compatible rims. Running tubeless can allow lower pressures, helping improve grip, comfort, and rolling performance over rough surfaces when used with suitable tubeless sealant and compatible wheels.
