Hollowgram Si Forged Crank Arm Set

The beauty of the Hollowgram system is that every part is interchangable. Not only can you use the same arms on your road and mountain bikes, but you can swap out whether or not you want to run a single, double or triple at a whims notice. Includes both drive and non-drive arms.
