1x 104 BCD Spider for SRAM Cranks

Run smaller chainrings on your SRAM and Truvativ cranks with the NSB 1× 104 BCD Spider. It replaces the stock chainring spider so that you can run smaller rings on XX1, X01, X1, X0, X9, S2210, GX, and S1400 cranks.

They are designed to use any standard 104 BCD 9, 10, or 11-speed chainrings. 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. The outside tabs accept any standard bash ring for DH or aggressive All Mountain bike applications.

The 104 BCD Boost spiders are used to convert GXP cranks to Boost Compatible Frames.

Chainline:

• 50mm for GXP and BB30
• 52mm for Boost

Weight: 65 grams
