The TRP Inplace Adjustment brake pads allow the angle of the brake pad to be easily adjusted with an Allen screw. They work with most cantilever brakes using a smooth (non-threaded) post brake pad holder. They are a great solution for easy and precise adjustments. The TRP Inplace Adjustment brake pads come as a complete set with four pads and holders for one bike. Select alloy rims or carbon rims.
