If you want accurate and precision gear changes and shifting, don’t neglect your pulley wheels. The excellence XLC Gear Shift Pulley Set PU-A02 guides the chain through the rear derailleur and onto the cassette along the ideal line for perfect shifting. Available in a gorgeous green colour, not only will they improve the performance of your bike, but they’ll enhance the look of it too. Available in a set of 2, you can perform a full replacement of both pulley wheels at the same time, or save one for later, depending on how worn out your existing wheels are. XLC have used sealed pulley wheels to prevent dirt and water ingress from getting into the bearings. This also makes it easier to maintain as you don’t need to worry about re-greasing the bearings inside, you simply replace the full pulley. The PU-A02 pulley set is compatible with Shimano 8-, 9-, 10- and 11-speed systems, as well as Campagnolo’s 9- and 10-speed drivetrains.
