Appleman Bicycles expert Repair Service can replace damaged carbon or aluminum dropouts. The size, tolerances, and forces often require that damaged dropouts be completely replaced. To replace a dropout, Appleman custom molds a dropout to match the shape of any tube. The damaged dropout is removed and the new dropout is bonded and laminated with carbon fiber just like our custom frames!
This Cervelo R3 had a very small hanger with very little material at the dropout. The owner snapped the dropout while installing the rear derailleur! A custom carbon dropout was added with an Appleman hanger.
Before: Guru Photon from Singapore has a full carbon fiber dropout that was cracked in shipping.
After: Appleman Bicycles carbon dropout bonded and laminated. The square shape of the stays would make machining an aluminum dropout impractical.
Before: Trek Speed Concept aluminum dropout was damaged beyond repair.
After: New Appleman style dropout accepts aero seat stays and small chain stays. The internal routing was maintained and modified to the exit through the reinforced chain stay. The paint was kept “rough” to match the weathered look of the original paint job.
