I noticed my KHS MTB has what looks like one of those Travel Agent contraptions on the RD cable, right where the cable enters the RD mechanism. Is that what it is? If so why would it be on there?
Or is it just something to help the cable make that sharp curve, since the cable is routed down the seat stay instead of the chain stay like my road bike? It looks like it says Avid on it, but I didn't see anything like that on the Sram Avid site.
