Not sure? Send photos — we check before you payA bent, floppy or seized rear derailleur causes skipping and missed shifts. This long-cage derailleur is listed for 6- and 7-speed systems (model RD-TY300-SGS in the manufacturer's feature list), in aluminum alloy, with 13/13T pulleys.
Listed capacity: 43T total; largest sprocket 28T to 34T; smallest sprocket 11T to 14T. The listing says it works with 6 and 7-speed SIS-type index shifting, and suits mountain, hybrid, road, folding, kids, cruiser and electric bikes.
Check before you order: the mounting type. The manufacturer's feature list says bracket fit (under the wheel nut), while the listing title says direct mount, so email us a photo of the spot where your derailleur bolts to the frame before you order and we will confirm which mount you need. Also count your sprockets (6 or 7) and check that your smallest and largest sprocket fall inside the ranges above. This derailleur is not for 8-speed or higher systems.
After fitting, set the limit screws and the cable tension so the chain shifts cleanly across all sprockets.
