Fits any 104 BCD crankset.
Chainring Bolts: All tooth sizes require 1x bolts that are 6mm long with exception to 30T rings which are threaded and require bolts that are 7-10mm long.
104 x 30T - use 10mm bolts.
104 x 32T, 34T, 36T, 38T use 6mm bolts, unless using a Bash ring.
Chainring bolt requirements for bashring
104 x 30t - 10mm bolts are required for use with the bashring.
Other 104 BCD sizes - you will need 8mm bolts (stock size that comes on 3x cranksets holding the middle and big rings on). Wolf Tooth does not make these.
32t 104 BCD chainrings work on many older 2x Shimano crankset (XT, SLX, or Deore).
All sizes of 104 BCD chainrings are compatible with QUARQ power meters.
The Wolf Tooth 30T is the only 104 BCD chainring made in the market, and it is compatible with Quarq.
Drivetrains: 1x9, 1x10, 1x11 and 1x12 drivetrains
• If using a 9-speed drivetrain, use a 10-speed chain. It fits tighter for better chain retention.
