Anyone who cycles has to replace their jockey wheels once in a while. With racing bikes normally once a year, with mountain bikes a couple of times per season is not uncommon. For well-working 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 (UPPER) and the wider wheel below (LOWER). The durable, self-lubricating plastic combined with high-grade precision bearings, guarantee wheels that continue to turn easily, even under extreme conditions.

ProsEasy to fit, work wel.
These are provided with a number of washers to fit different mechs. I am using them on an old 8 speed Shimano stx. They were easy to fit and were fitted at the same time as a new block and chain the result is a much smoother drivetrain and slik changing. Can't tell how much of the improvement is down to the jockey wheels. Only time will tell if the bearings are resistant to ingress of water/dirt.
