We carry a ton of Ridley bikes. Ride them long enough, or through shipping and travel, and a bent or broken hanger is sure to happen. If it's bent and not broken, you can try to straighten it, but it's inherently weaker and your shifting will be severely compromised. Pick up these Wheels Manufacturing Derailleur Hangers, for Ridley, and get your bike back to shifting like a champ. Keep some spares in your toolbox too so you'll never be stranded without your bike. CNC machined from 6061 aluminum and anodized black, these hangers are a direct replacement for the OEM hanger and it comes with (2) M4x10 flat head screws for a quick and easy install. Please note that this hanger is compatible with Ridley's 2015 Fenix Disc, 2015 Helium, 2013-15 Helium SL, 2015 Noah SL, 2015 X-Night, 2013-14 X-Night Disc CX, and 2015 X-Trail.
