A Nimbus ISIS 36 hole hub with ultra high strength ISIS spline CrMo spindle. Built to be more robust and durable than the traditional cotterless, or standard splined hubs. Compatible with all 42mm bearings and 42mm machined frame housings.

Notes:

• This hub will fit all ISIS cranks except Koxx ISIS cranks.
• This hub utilizes 42mm bearings, and is compatible with 42mm frame/bearing housings only.
• This hub will not fit in frames with machined bearing housings designed for 40mm bearings. It requires either pressed bearing housings or frames machined to take these larger bearings.
