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 (rain, mud). Suitable for Shimano 7- & 8-Speed, Campagnolo 8-, 9- and 10-Speed, SRAM-ESP< 2000. Colour black, red, blue, yellow
For Shimano 9-speed we have special 11-toothed wheels available GP4050
