Indian
Alpha Bearings part number IND1 and IND2 employ standard imperial rollers and must be purchased as a complete assembly. The "Fork and Blade" design requires the connecting rods to be returned to Alpha Bearings for the bearing outer races to be fitted. Once fitted these outer races are machined to ensure that any hint of ovality is removed from the bores and that the "truth" of the rods is perfect.
