1x 104 BCD Spider for SRAM Cranks
The NSB 1× 104BCD Spider replaces the stock chainring spider so that you can run smaller chainrings on Truvativ 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 bashring for DH or aggressive All Mountain bike applications.
The 104BCD Boost spiders are used to convert GXP cranks to Boost Compatible Frames.
Chainline: 50mm for GXP and BB30
52mm for Boost
Weight: 65 grams
