As supplied on the Nimbus ISIS range of unicycles. Two types to fit 40mm and 42mm bearings.
These Nimbus machined bearing clamps are much better for your bearings as they ensure there is a more even load on them. This means the bearings should run smoother and last longer.
These clamps are designed to fit Nimbus ISIS frames. 42mm fit Nimbus II ISIS frames such as those on the Nimbus Trials ISIS and variants, Nimbus 24" and 26" Muni, Nimbus 29er, black (ISIS) Nimbus 36". 40mm fit older Nimbus X frames and blue (non-ISIS) Nimbus 36" frames.
Sold in pairs; each pair comes with four frame bolts.
