Wolf Tooth Elliptical 64 BCD Chainring - 30t, 64 BCD, 4-Bolt, Drop-Stop, Black

Designed to fit the inner 64 BCD spacing on 104/64 cranksets, it allows the use of a 30T elliptical ring on a 64/104 crankset. It's best paired with a 104 BCD bashring.

• The simplest way to explain the way these rings feel is having 2 teeth less in the weak part of your pedal stroke and 2 teeth more where you have the most power
• Features Wolf Tooth's Drop-Stop tooth design for maximum chain retention
• Drop-Stop chainrings are designed for use with 1x9, 1x10, 1x11 and 1x12 drivetrains
• Compatible with all 10-, 11-, and 12-speed chains, with the exception of Shimano 12-speed chains
• Shimano 12-speed chains require the use of Wolf Tooth's Shimano 12-speed specific chainrings
• If using a 9-speed drivetrain, use a 10-speed chain, which will provide a tighter fit for better chain retention
• Made from 7075-T6 aluminum for long life
• Use of a clutch-style rear derailleur is recommended
• Can be used with a 104 BCD alloy bashring
