Anyone used non Sram jockey wheels as £30 a go and last 3 months is not VFM in my world. Don't mind spending if it lasts.
I use some of the ebay metal ones (far sports I think), been great for the past few months/1800km of mud!
Aest (from cyclomonster) at a mere £7 a pop are a no-brainer. they look great and they're lasting far far longer than any SRAM ones I've used
KCNC ones from ebay. Far better - cheaper, last longer, need cleaning less and a bit more bling.
I bought a set of [url= http://www.ebay.co.uk/itm/171552783238? ]these[/url] about 3 months back, I'm using them in a shimano mech but seem to be wearing well, as still look nearly new.
Decathlon sell them. Can't remember if they're own brand or BBB, but they come with tophat spacer things to fit various mechs.
KCNC? Worth a go.
