This product is a rare Shimano RD-600 rear mech and triple braze-on front changer in a stylish silver colour. The front derailleur is designed for 10-speed bikes, providing smooth and precise gear changes. With the braze-on mounting type, this component is securely attached to the bike frame for optimal performance. Ideal for cyclists looking to upgrade their bike's components with high-quality Shimano parts. These are quite rare as they are the triple front changer and long cage rear mech so gives you a wider gear ratio, both in good condition with some spidering marks to the alloy and noticed the jockey wheel is split on the rear mech, please note the front is a braze on fitting not hanger but I think they can be converted.
