I have a Specialized Tricross (basic version) but I am finding that the brakes are a bit weak compared to my old Ridgeback Comet. The Tricross needs a lot more pressure on the lever to get the same effect as the Ridgeback. Swapping between the 2 bikes can get a bit "interesting" as I tend to find myself almost doing stoppies on the Ridgeback, and having brown trouser moments when the Tricross takes a bit too long to stop! Can anyone recommend an easy fix such as better brake blocks? If so, which ones?
