Spare spacers and hardware for mounting a 104 BCD chainring to an Ochain spider. Use it to move the chainring out for a different chainline, or to replace lost or used bolts.

Highlights

• Four 3 mm chainring spacers
• Short and long chainring bolts and nuts
• Aluminium hardware (M8.5 x 0.75 nuts, per SRAM)
• Listed by SRAM for Ochain R, N, S and E

Which bolts to use

SRAM's Ochain manual calls for the short bolts and nuts when the chainring sits directly on the spider (3 mm offset), and the long bolts and nuts with a 3 mm spacer (6 mm offset, for 56.5 mm DUB DH chainline) or a bashguard. Chainring bolts are factory treated with one-time threadlocker, so reapply it if you reuse them, and tighten SRAM bolts to 9 N·m.

Compatibility and fit

Fits Ochain Gen B spiders (R, N, S and E). A bashguard combined with a spacer is not a compatible setup. Fitting needs the right tools and the SRAM service manual, or book it in with a workshop.
