Standard Features
Over the last few years we have ben asked to fit ceramic bearings into our performance wheels. For a long time we have resisted as we have not been able to find a ceramic bearing of sufficient quality to cope with the stresses of wheelchair racing.
Most ceramic bearings have poor fitting, ungraded balls which are fragile. We have seen shattered ceramic balls and cracked ball races, due to the misalignment from the camber and the pounding loads from pushing.
These CeramicSpeed bearings might be a little more expensive than the cheap Chinese ones sourced from eBay etc, but they will pay for themselves in quality and longevity. More information here.
