Sram GXP crank arm bolt assembly
So...you made a mess of the non-drive side fixing bolt on your Omniums?
Remove the whole assembly, replace it and don't be such a hack this time!
• aluminum self-extracting bolt assembly only for use on GXP cranksets
• bolt/cap size: M15/M26
• dust cap installs using a 10mm allen wrench
• available in black or silver
This will not work on Sram S300.
Some older versions of Sram GXP cranksets use a huge 16mm allen wrench to remove the outer dust cap. Have fun with that!
