Jockey wheels need replacing once in a while.
With racing bikes normally once a year, with mountain bikes a couple of times per season is not uncommon.
For precise gears, Tacx delivers the perfect guides.
The closed ball-bearing circuit prevents the jockey wheels from jamming, play and irritating noises during cycling.
Ideal gear shifting with the narrow wheel above (Top) and the wider wheel below (Bottom).
The durable, self-lubricating plastic combined with high-grade precision bearings, guarantees wheels that continue to turn easily, even under extreme conditions.
The fixed top wheel helps compensate for wear on worn rear gears.
Come with four sets of spacers for use on the following:-
A - Shimano 8, 9, 10 & 11 Speed.
