WHEELS Mfg Derailleur Hanger 278

Because derailleur hangers are frame-specific, you should compare your current hanger visually to the images on the Wheels Mfg website or check your bike manufacturer's technical manual. The '278' model number is specific to certain frame geometries, so ensure your bike model is explicitly listed as compatible before purchasing.

CNC machining allows for tighter tolerances and higher precision than traditional casting or stamping. This results in a more rigid, durable part that ensures your derailleur is perfectly aligned, leading to smoother and more reliable shifting.

No, the derailleur hanger is designed as a 'sacrificial' part. It is meant to bend or break during an impact to protect your frame's more expensive rear triangle from structural damage.

Installation typically requires only basic hand tools, such as a set of hex keys, to remove the mounting bolts from your frame. Ensure you have a small amount of grease for the threads and be careful not to overtighten the bolts, as they are designed to be snug but not crushed.

It is a smart practice to keep a spare hanger in your saddlebag or tool kit, especially if you are heading out on a remote ride or a multi-day trip. Since a bent or broken hanger will effectively disable your drivetrain, having a direct replacement on hand can save your ride.
