SRAM X4 rear derailleur in black with a long cage, 1:1 cable pull and 34 tooth max sprocket, in stock now at our Kennington workshop.
The SRAM X4 is a rear derailleur listed for 7/8 speed, with the supplier's specification sheet giving 9/8/7 speed, a 1:1 cable pull ratio and a maximum sprocket size of 34 teeth. That 1:1 ratio and the tooth limit are the two numbers to check against your shifter and cassette before ordering, since they decide whether the shifting lines up and whether the cage can wrap your largest sprocket. The long cage suits wider gear ranges, the cage is aluminium and the pulleys run on steel bearings.
A sensible replacement if your current mech is bent, worn or shifting poorly, and a straightforward black finish that sits quietly on most builds. We have it on the shelf in Kennington for free click and collect, and our mechanics can fit and index it for you the same day.
