Keep your gears shifting smoothly with derailleurs and spares from the BIKE shop in North Harrow. Established in 1988, we stock front and rear derailleurs to fit road, mountain and gravel bikes, from budget-friendly replacements to high-performance upgrades. A worn, bent or poorly adjusted derailleur can cause missed shifts and a noisy drivetrain, so if your bike isn't shifting the way it should, our workshop team can diagnose the issue and fit a replacement or carry out a full gear adjustment. We stock derailleurs to suit a wide range of groupsets and speeds, and our staff can help you find a compatible option if your original part is no longer available. Every fitting is carried out by trained technicians, so you can be confident your gears will shift accurately and reliably. If you're not sure what your bike needs, bring it into store and our team will help you find the right part. Conveniently located in North Harrow, we proudly serve cyclists across Harrow, Pinner, Ruislip, Wembley, Watford and North West London with expert drivetrain servicing.
