Joe A.wrote a review of K-Edge PRO Braze-On Chain Catcher on July 26, 2016
Familiarity: I returned this product before using it
Well, this is the second K-Edge Pro Chain Catcher I've purchased and both have had the same issue. There wasn't a bolt long enough to work with the SRAM front mech. In the specs they list a couple of sizes of attachment bolts. The shrink wrapped package should have a total of 3 bolts. Don't take off your derailleur like I did expecting all of the parts to be there if you're using SRAM.
