This kit is designed to plug the cable holes in a Trek Top Fuel 9.8 when using a SRAM AXS wireless derailleurs. The kit includes all the plugs needed to make the frame just a single hole for the rear brake line. It also has a blank plug for the side of the frame where you no longer need cable routing. This is for a TOP FUEL 9.8 but will probably fit other TREK mtb frames (however, it is not tested on any other frames).
