Wolf-tooth Wolf Tooth 104 BCD Chainring Drop-Stop ST For Shimano HyperGlide+ 12S Black

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.

Main features:

• 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.

Features:

• Tooth profile: Drop-Stop ST.
• Weights: 47 g (32T) / 56 g (34T) / 60 g (36T) / 66 g (38T).
• Material: 7075-T6 aluminum.
• Made in the USA.

Compatibility:

• Compatible with any 104 BCD crankset.
• Wolf Tooth’s patented Drop-Stop wide/narrow tooth profile for the ultimate chain retention and mud shedding ability.
• All rings sizes require 1x bolts that are 6 mm long. If using a bashring you will need 8 mm bolts (most stock bolts on 3x cranksets are 8 mm).
• 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.
• 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.
• Compatible with 12spd Shimano HyperGlide+ chain only. Symmetric Trapezoidal (ST) tooth shape is optimized for Shimano HG+ chain.

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.
