Chain tensioner from tca.gt series by Gilles Tooling. Thanks to innovative angular gearshift, the chains is adjusted very carefully. In the contrary to serial tensioners, it may tighten or release the chain. By installing the tensioner to the swingarm, the rear wheel assembly is easier. The scaling provides readings with high accuracy in "mm" and can be used to determine the tolerance limits. Optional crash pads (60150400090) may be installed to protect the swingarm and the axle from damaging, and Moto GP look lifter (from 60150400060) for the machine to be easily lifted.
