Got these fitted to the bike as standard. Integrated with the brakes, roady style But they were OEM parts and didn't come with any instructions/exploded diagrams etc. Now I can see that at some point in the future I'll need to do some sort of maintenance. It'd be nice to know what to expect before I consider taking a screwdriver to them. Think its about the only thing my copy of 'Zinn' which I got for the MTB won't cover. Anyone able to point me to a suitable site or have scanned images of the original instructions?
