The nice part about the Litespeed C1R /C1/C2/C3 Derailleur Hanger is that its design places the threads for the fasteners in the hanger itself, rather than in the dropout on your frame. So a stripped bolt hole is no big deal -- an inexpensive fix. It's also a failsafe for your carbon fiber frame in the event of a crash. The hanger is designed to fail before your frame will, again meaning that you have a cheap, easy repair. We've always heard that good preparation is the best defense, so if you have a Litespeed C-series bike, you should have one of these C1R /C1/C2/C3 Derailleur Hangers in your tool kit just in case. Its minimal design is possible because it's made of plated steel and comes with two hex keyed fasteners.
