North Shore Billet

1x Spider for SRAM XO Carbon Cranks: 104 BCD Boost Chainline Spacing

The North Shore Billet 1x Spider allows you to run smaller chainrings on your SRAM and Truvativ cranks. It replaces the stock chainring spider so that you can run smaller rings.

• There are no mounting holes for the granny ring and the single ring?s position has been moved to give a better chainline throughout the entire gear range
