Wolf Tooth Chainring, 104 BCD Drop Stop B - black

104 BCD is the most common bolt pattern for double and triple cranksets and coincidentally the first product ever made by Wolf Tooth Components. With this chainring, everything started for us. The Drop-Stop® - tooth design is the most efficient and durable wide/narrow chainring on the market.

Features:

• Fits any 104 BCD crankset.
• Designed to meet the demands for e-bike use.
• Chainring bolts: All tooth sizes require 1x bolts with a length of 6 mm, except for 30T chainrings, which are threaded and require bolts with a length of 7 - 10 mm.
• 104 x 30T - use 10 mm bolts
• 104 x 32T, 34T, 36T, 38T use 6 mm bolts, unless you are using a bash ring.
• Chainring bolt requirements for bash ring
• For use with the bash ring, 104 x 30T - 10 mm bolts are required.
• Other 104 BCD sizes – You need 8 mm bolts (standard size found on triple cranksets to hold the middle and large rings). Wolf Tooth does not make these.
• 32T 104 BCD chainrings work with many older 2x Shimano cranksets (XT, SLX, or Deore).
• All sizes of 104 BCD chainrings are compatible with QUARQ power meters.
• The Wolf Tooth 30T is the only chainring made on the market with 104 BCD  and is compatible with Quarq. This chainring is offset by 2 mm.
• Drivetrains: 1x9, 1x10, 1x11, and 1x12 drivetrains
• If you are using a 9-speed drivetrain, use a 10-speed chain. It fits tighter and thus provides better chain retention.
