Derby Rims proudly inform us that their new Sol Rider carbon rims have survived a 3 year battering by DH racers, free riders and mechanical testing. Hence, the “unbreakable” claim, and the 5 year free warranty replacement they offer with the purchase of any rims in the Sol Rider line-up. Why are they so tough? It’s all down to Derby Rims’ new Solstice layup… we have the details.

Derby Rims Solstice Layup
So what on earth makes Derby Rims new Sol Rider hoops tougher than their original MTB carbon rims, which themselves have a 0.5% damage rate over 3 years? That would be the proprietary Carbon Fiber Reinforced Polymer (CFRP) hybrid layup of carbon-fiber and plastic fiber composites. Not only does it maker them tougher, but it also gives rise to a much smoother ride feel.
The plastic fiber layers microscopically stretch between alternating layers of carbon fiber in the Solstice layup. When flexed excessively by hard impacts the Sol Rider’s rim wall flex tolerance prevents micro-fracturing, the initial separation of an internal layer’s carbon fibers. In turn, this prevents further separation of internal layers and ultimately, rim failure.
With the engineered flex, you may well expect the rims to offer more compliance, and thus a smoother ride feel than the original carbon rims.
“These are the smoothest carbon-fiber composite rims I’ve ever ridden” – CAT-1 masters DH-racer Kevin Dwyer.
