A good choice for a 10-speed road-bike owner who wants a dependable replacement derailleur and extra cassette range for hilly riding, touring or everyday use.
This is a 10-speed road rear derailleur for riders replacing a worn unit or refreshing an existing drivetrain. The GS medium cage gives you useful range for climbing-focused setups, supporting a maximum 34T low sprocket with a front double or 32T with a front triple, subject to the rest of your drivetrain configuration.
On the road, Double Servo operation is designed to provide a smooth, light shifting action across the cassette. The built-in cable adjuster makes fine indexing adjustments straightforward, while the 41T total capacity helps accommodate a wider spread of gears than a short-cage derailleur.
Before ordering, check your shifters, cassette and derailleur hanger carefully. This model uses a conventional SHIMANO ROAD-type direct attachment and is designed around HG-X 10-speed chains. Older 10-speed road shifters are not automatically interchangeable with this derailleur’s cable-pull system, so confirm compatibility rather than assuming that a different 10-speed control will index correctly.
