SRAM Eagle S100 Rear Derailleur

The SRAM Eagle S100 rear derailleur is part of the new SRAM S100 series. This groupset is designed with a focus on durability and a good price-quality ratio. It is SRAM's entry-level series for a reliable system with an expanded gear range. SRAM keeps the groupset simple but it offers everything you need. Due to the focus on robustness, the S100 series is also suitable for use on electric mountain bikes. The reinforced cage makes this derailleur very strong and highly impact-resistant.

The derailleur can be reinforced on a UDH frame with a half-mount hanger plate, increasing strength and shifting precision. X-Actuation technology ensures reliable gear shifting under pressure. The drag spring cage ensures that the chain is always tight and, therefore, less likely to come off or clatter against the frame, allowing for a quiet ride.

Great cassette range
The possibility of using a cassette up to 50T allows for a range of as much as 500%. This is plenty to let you tackle steep climbs comfortably.

Drag spring cage
The drag spring in the cage ensures excellent chain tension and retention. Thus, the chain remains tight and securely in place even on rough terrain.
