If you have an SRM crankset, you're going to want one of these. The clever K-Edge design allows you to have a chain catcher and an SRM magnet in the same device. This means no more dropping chains and no need to attach the sometimes pesky stock SRM magnet to your frame.
Bottom line is, if you have an SRM crankset, buy this product. Bomber 6061-T6 CNC construction from solid billet makes the mount virtually indestructible. All edges have been chamfered and polished for a smooth touch. Anodization adds some color and additional durability. These mounts will fit any standard braze-on front derailleur mount.
