Rear Derailleur Hanger Dropout

This hanger is specifically engineered for BMC frames using the Dropout 70 standard, including the Teammachine SLR01, SLR02, and SLR03 Disc models from 2018-2021, as well as the Timemachine Road 01 Disc and URS. Always verify your bike's specific dropout shape against the product image, as even small variations in model year can require a different hanger.

CNC machining ensures precise tolerances and consistent alignment, which is critical for smooth gear shifting. Unlike cast or stamped alternatives, CNC-machined aluminum provides better structural integrity and durability, ensuring the hanger performs reliably under the tension of your drivetrain.

No, the derailleur hanger is designed as a sacrificial part. Its primary function is to bend or break during an impact to absorb energy and protect your expensive carbon or aluminum frame from catastrophic damage.

Installation typically requires a standard set of hex keys to remove the mounting bolts from your existing dropout. While the process is straightforward, ensure you have a torque wrench to tighten the bolts to the manufacturer's recommended specifications to prevent stripping the threads.

Yes, keeping a spare hanger in your saddlebag or toolkit is a smart practice for any cyclist, especially on gravel or road rides far from home. If you suffer a crash or a derailleur strike, a bent hanger can end your ride immediately, whereas a quick swap will get you back on the road.
