Product Details

Pearson Bump and Grind remains the wheelset of choice for gravel riders the world over. With a durable, carbon-fibre rim, this tubeless-ready wheelset ensures unrivalled stiffness and optimal power transfer. The broader internal width, of 21mm, helps larger tyres sit smoothly on the rim, maximising rider comfort and confidence. Off-road conditions can be unpredictable, which is why our Bump and Grind rim has also been designed with a shallower depth, of 28mm, offering exceptional stability during crosswinds.
To ensure longevity, we laced our carbon rims with 24 spokes on each wheel. The precision, sealed-bearing hubs offer all-weather resilience, while the thru-axle design aims at stability comparable to mountain biking. Our wheels are one of the lightest gravel-specific sets on the market with a lightweight combination keeping them nimble regardless of the terrain. Especially welcome when loose, gravel tracks pitch upward!
