Wolf Tooth 104 BCD Spider Mountain Bike Chainring for Shimano 12spd Hyperglide+ Chain (32 Tooth, Drop-Stop ST, MTB) — Open-Box, 14% Off

104 BCD is the most common bolt pattern on double and triple cranksets and happens to be the first product ever made my 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

• Drop-Stop technology. On Wolf Tooth’s 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

• 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.

• 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 30T has a relief notch to meet QUARQ power meter minimum internal diameter requirements power meter

• 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

Available in two different tooth profiles for optimal performance based on your chain type. Use Drop-Stop ST for use with Shimano 12-speed Hyperglide+ chains. Use Drop-Stop A for all 9, 10, and 11spd chains or 12spd SRAM Eagle, KMC, Connex or Wippermann chains.
