Everything has been done to make this New MT ZOOM jockey wheel carry your chain faster and smoother.
We have these in RED or BLACK
Cut from 7075 red alloy - extra machining has lowered the weight to 5.6g.
High quality ceramic bearings.
Replace those tired black plastic ones that come with most derailleurs.
These are compatible with all derailleurs that use a 11 tooth jockey wheel and have a hole in the centre, e.g. Shimano systems (e.g. XTR, XT, Dura Ace etc) and most SRAM systems. Tested in tough conditions, they hold up very well.
There is a little lateral movement to move with the derailleur & enable a better chain line.
