    • SRAM X4 Rear Derailleur is rated 4.7 out of 5 by 12.
      Rated 5 out of 5 by from The best of SRAM This rear derailleur is excelent because I had this for years and is still working

      Rated 5 out of 5 by from SRAM or Shimano? My experience has been that at the budget end of their respective ranges, SRAM derailleurs are longer lasting than Shimano. The pivots seem to have more slack from new and wear quicker on Shimano leading to the guide/jockey wheels going out of alignment to the cassette and chainset, causing chatter and poor gear changes. The SRAM X4 has served me very well and so I am replacing with the same. Will likely move to SRAM in the future for other bikes.

      Rated 5 out of 5 by from Excellent replacement for my broken part I broke my rear derailleur and this was the perfect replacement for it

      Rated 4 out of 5 by from Replacement on Crossfire 3 I mangaged to munch up the derailleur on my Crossfire 3, so brought this replacement. Noatably, this is the long arm version , but it worked straight away when fitted. Once on gear was aligned, it shifted nicely to all the others. Don't forget to get a rear mech hanger if you've bent it too!

      Rated 5 out of 5 by from SRAM X4 Rear Derailleur Excellent replacement for an existing SRAM SX4 model that was originally fitted to a friend's bike (Carrera Crossfire 2). In tandem with a replacement gear hanger (Type A from Halfords), an 8 speed KMC chain and a Shimano 8 speed cassette, the bike's shifting has been transformed. The derailleur is sturdy and easy to fit. Excellent instructions accompany the product with no prior knowledge really required. Would definitely recommend. Not the lightest, but for the price, and excellent piece of kit.
