The critically acclaimed Bling Ring is now available for 30mm spindle cranks! For 2014 we offer the standard Bling Ring -6 for GXP and Bling Ring +1 for PF30 and BB30. The +/- numbers communicate whether the ring is offset inboard or outboard. These sweet little chainrings mount directly to SRAM cranks that feature a removable spider. They save substantial weight compared to the standard chainring and spider combo. MRP Bling Rings are 100% made in the USA.
