SUPPORTS 104MM BCD: Bolt Circle Diameter (BCD) is 104mm for front cranksets with 4 bolts and 104 BCD spacing. 4 chainring bolts included. (Note: 30T chainrings are threaded and only require male bolts, not nuts.)
7075 ALUMINIUM AND CNC MACHINED: Made from 7075 aluminium alloy and CNC machined to ensure precision, lightness and durability for your bicycle chainrings
SUPPORTS 7 TO 12 SPEED SYSTEM: Installing this chainring can make your bike lighter and simplify the operation. It is highly compatible and supports 7/8/9/10/11/12 speed rear flywheel
WIDE NARROW TOOTH DESIGN: The teeth of this round chainring adopt the second generation wide narrow tooth design, which maximises the service life of the chainring and reduces friction and noise. The larger wide-tooth design improves the anti-dropout performance of the chainring
PERFECT as a replacement for an old chainring or as a conversion from a 2- or 3-speed chainring to a single front chainring. Please check the correct crank BCD specification for your bike before purchasing
