Product reviewsSRAM X4 8 Speed Rear Derailleur Road Mountain Bike MTB Cycle

High performance, low cost - what a stonking good mech!

Just replace the original jockey wheels with a couple of sealed bearing anodized alloy ones (a couple of quid off eBay) and you have a lightweight, high bling factor derailler, that performs like a top-of-the-range SRAM component!Read full review...

Replacing SRAM gear mech for non mechanical guy

Had to replace gear mech on mountain bike due to riding mishap.
Bought this one on eBay. Fitted it and adjusted it in less than half an hour. The mech came boxed and was a straight swap. Would recommend this to anyone in the same position as me.Read full review...

8 speed derailer

SRAM made this derailer,to to be bullet proof, used it in converting a road bicycle to gravel on with a 1 X 8 system.
If you want a cheap 8 speed derailer, don't look any further.
