Nimbus 48H ISIS Hub


Product Description

Built to be more robust and durable than the traditional cotterless, or non ISIS splined hubs. Compatible with 2007-2008 48 hole rims featured on the Nimbus II 20" & 24" ISIS cycles, Nimbus X 20" & 24" ISIS cycles, and all 42mm bearings and 42mm machined frame housings.

Note: This hub utilizes 42mm bearings, and is compatible with 42mm frame/bearing housings only.

Should you want to build the wheel, here is a link to the spoke calculator so you can find the correct spoke length you need.

  • Wide flange spacing for increased wheel strength
  • Flange material hardness and shape are designed to maximize spoke strength
