Needed different sized bearings to fit a front track axle kit since the newest model HED H3 has a slightly newer/updated Sonic hub with different sized bearings from previous H3s. Got the guys at my LBS to swap the bearings, get the track axle fitted, and it worked out perfectly. Super smooth and ready for the track.
Ordered two pair of ceramic ball bearings for my cycle hubs. Fast answers and fast delivery. Highly recommended. Errol Sweden.
Great product for use in replacing the Cartridge Bearing on the H.E.D 3c Tri-Spoke wheel. Smoothest rolling bearing I have ever used. From Wheel will free spin for what seems like forever. Rear wheel using this same cartridge and then loose bearing on the cassette side make riding the road faster than conventional metal cartridge bearing.
Outside tolerance larger than the swiss steel bearing that was removed.
