The Shimano 105 Rear Mech RD-5501 is a 9-speed rear derailleur designed for road bikes. Made from lightweight aluminium, this durable and high-quality component is specifically compatible with Shimano brand bikes. The short cage derailleur is perfect for achieving smooth and precise gear changes, making it ideal for cyclists looking to upgrade or replace their current rear derailleur. With a sleek silver design and a weight of 200-299g, this Shimano rear mech is a top choice for avid riders seeking performance and reliability. This one is still in good used condition with the usual scratches but would still polish up well, all working nicely, not sure if it’s short or medium cage so took a picture with the measurements to help.
