The Wheels Manufacturing Derailleur Hanger 163 for Cervélo is a high-quality replacement hanger designed to restore proper rear derailleur alignment and shifting performance on compatible Cervélo frames. A derailleur hanger is a sacrificial part that protects your frame and drivetrain by bending or breaking in the event of an impact, helping prevent costly damage to the derailleur or dropout. When a hanger gets bent — often after tip-overs, transport knocks, or crashes — shifting can become imprecise, noisy, or outright unreliable. Replacing it with a true fit-specific hanger like the #163 lets you return your bike to crisp, accurate shifting quickly and confidently.

Manufactured by Wheels Manufacturing, this hanger is machined from durable materials with precision tolerances to ensure reliable alignment and long service life. It attaches securely to the frame and positions the rear derailleur at the correct height and angle relative to the cassette, which is critical for smooth gear engagement and drivetrain efficiency. Because each hanger design matches the frame’s geometry, using the correct model — in this case, #163 for select Cervélo bikes — helps maintain the intended shifting feel and performance from your drivetrain.

This hanger is a practical spare for riders, mechanics, and workshop toolkits alike — especially if you frequently travel with your bike, ride in tight bunches, or push hard on technical terrain where hanger damage is more likely. Having the exact replacement on hand makes roadside or shop repairs much simpler and keeps you rolling with minimal downtime.
