104 BCD is the most common bolt pattern on double and triple cranksets and happens to be the first product ever made by Wolf Tooth Components. This chainring started it all for us. The Drop-Stop tooth design is the best performing and longest lasting wide/narrow chainrings on the market.

• Fits any 104 BCD crankset.

• Drop-Stop technology. On Wolf Tooths patented wide/narrow chainring, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris which reduces friction.

• Alternating wide/narrow tooth pattern prevents chain derailment.

Compatibility

• Fits any 104 BCD crankset.
• Designed to meet the requirements for E-bike use.
• 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 -use10mm bolts.
• 104 x 32T, 34T, 36T, 38T use6mm bolts, unless using a Bash ring.
• Chainring bolt requirements for bashring
• 104 x 30T -10mm boltsare required for use with the bashring.
• Other 104 BCD sizes -you will need8mm 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 30Tis the only 104 BCD chainring made in the market,and it is compatible with Quarq. This chainring isoffset 2mm.
• Drivetrains: 1×9, 1×10, 1×11 and 1×12 drivetrains
• If using a 9-speed drivetrain, use a 10-speed chain. It fits tighter for better chain retention.

Recommendations

• If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur. Without these precautions, you may experience chaindrops and/or chainsuck.
