Bent hangers happen. A bike tips over in a parking lot, the rear derailleur catches something during a group ride, or the frame just takes an impact in the wrong spot. The Cervelo Threaded Axle Derailleur Hanger gives you the factory replacement part that restores shifting alignment without a trip to the frame builder. This hanger fits all disc brake-equipped frames from 2015 onward, covering the S-Series, R-Series, P-Series, PX-Series, C3, C5, Caledonia, and Soloist platforms. The only exception is the P5X, which uses a different dropout configuration.

Beyond crash replacement, this hanger serves another purpose: converting R.A.T.-equipped bikes to standard threaded thru-axles. If you're tired of the proprietary Rapid Axle Technology system and want to run conventional 12mm thru-axles instead, this hanger is part of the conversion kit. Pair it with the Cervelo threaded fork insert and standard thru-axle levers, and you've eliminated the R.A.T. system entirely. Some riders prefer this setup for trainer compatibility or simply because they like the feel of traditional thru-axle operation.

The hanger itself is CNC machined from 6061 aluminum with a black anodized finish for corrosion resistance. The M12x1.75 threads accept standard thru-axles, and the derailleur mounting tab maintains the same geometry as the original equipment hanger for consistent shifting performance. Aluminum construction means the hanger bends before your frame does in an impact, which is exactly what you want from a sacrificial component.... Read More
