Raleigh America Diamondback Derailleur Hanger- 7 (Black)

Fits my Diamondback Steilacoom RCX 2013 perfectly.One note though: if you had to replace the original after it broke or got bent, that's probably because your rear derailleur got caught into you spokes. Make sure that you adjust the stopper screws of your derailleur so that this doesn't happen again. I didn't. After replacing the hanger I went for a ride in the hills and pushed my rear derailleur in my wheel again. But this time the hanger didn't break - the derailleur itself was snapped in half!
