Wolf Tooth 104 BCD Chainring Drop-Stop A

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. The Drop-Stop® tooth design is the best performing and longest lasting wide/narrow chainrings on the market. • 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. Wolf Tooth carries both sizes in a variety of colors. • 104 x 30T - use 10mm bolts. • 104 x 32T, 34T, 36T, 38T use 6mm bolts.  • If using a bashring, you will need 8mm bolts (most stock bolts on 3x cranksets are 8mm). • 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. • 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.
