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, 11, or 12-speed chainring. 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 convert GXP cranks to Boost Compatible Frames.

Specifications:

Chainline

50mm for GXP and BB30
52mm for Boost

Weight: 65 grams
Machined from solid 6061 Aluminum
Anodized Black with Laser Etched Graphics

Surface finish could have been better.

https://www.youtube.com/watch?v=n-ZgWsvWBYI Are you making the final machining cuts too deep perhaps?

Hi, Leslie. Thanks for the review and you’re keen eye. We’d like to clarify some things: 1) the spiders are made using 6061-T6 material. Our stems are also made from this. 2) We don’t put the spiders through the rigorous polishing process as we do with stems, chainrings and other parts. Not all parts are polished after machining, and given the spider’s position on the bike and use, we opt not to add the extra step to the manufacturing process.

Had a question before the purchase and Chris was quick to reply. Item was shipped out the same day with tracking updates and arrived as scheduled. Also, the quality and workmanship of the product is top shelf. It is how online shopping should be, overall excellent experience.

Spider 1x104 BCD - GXP, SRAM XO1 Single speed build

Great!!! Chris was awesome and answered all my questions. I needed the right spider for my new crank to run Gates belt drive single speed. It fit great and to the exact factory measurement of 52mm chainline with the XO1 crankset. NSB is an awesome company and take pride in customer service.
