  • Prime Orra 650B Carbon Gravel Wheelset

    Sending you through forest pathways and gravel routes with ease, this Prime carbon 650b wheelset is a venturesome and versatile wheelset for the curious cyclist. Whether touring around town or taking the road less-travelled, the Kanza is sturdy and stiff, whatever the terrain. With a 32mm inner and 30mm deep rim profile, each wheel gives unbeatable balance on every journey.

    Carbon-Rimmed, Top-Performance Gravel Wheels

    The carbon construction of the rims ensures a responsive, easy-to-handle performance, with the double-butted Pillar spokes bolstering each build for hitting small trails and rocky tracks at pace. Spinning on a set of CNC-machined RD020 hubs, both wheels deliver a consistent roll on irregular ground, maximising comfort and control. The rear hub also benefits from a 9/10/11-speed freehub for added thrust when you need it most.

    With tubeless-ready compatibility and center lock disc brake mounting, the Prime Kanza 650B Carbon Gravel Wheelset is a hard-wearing and fast-rolling wheelset for your gravel-grinding endeavours.
