Overview
Why choose the Wheels Mfg Derailleur Hanger 303?
The Wheels Manufacturing Derailleur Hanger 303 is a CNC-machined replacement hanger that runs stiffer than almost any OEM hanger, which keeps your derailleur truer to its indexed position under load and translates into crisper, more consistent shifting. It is cut from 6061 aluminum and finished in black anodize, and like every Wheels Manufacturing hanger it is made in the USA to tolerances that meet or exceed the original. As a sacrificial component, it is designed to take the hit in a crash so your frame dropout does not.
The 303 fits Cannondale frames and replaces Cannondale part numbers KP419 and K33049. Note that it is designed for M12x1 single-lead threaded axles and is not compatible with the Speed Release axle on the 2019 and newer SystemSix, which uses a double-lead thread. Attachment hardware is not included. Since manufacturers sometimes change hangers mid model year, confirm fitment against the product photos before ordering. Best for Cannondale owners who want a stiffer, better-shifting replacement and a smart spare to keep on hand for race day.
