Spice up your unicycle by adding a bit of carbon! These Carbon Spacers are designed to fit on ISIS hubs, sold in pairs.
Replacement spacer for Kris Holm and Nimbus ISIS hubs, these space the cranks away from the bearing which is part of the ISIS system. Due to the variance in tolerance on the tubes and cranks changing the thickness of the spacers is essential to maintaining the integrity of the ISIS interface. Replacement spacers can also be required when ISIS interface is worn due to regular crank changes.
