Grip off the old blocks.

Have been conscious since the 3 Peaks Cyclocross race that my bike has been under-braking, but hadn't realised how worn the rear blocks were until I removed them today. Almost worn to nothing from new. In one race. However, no time to do anything about it before Sunday's Scottish CX Championship race in Dunfermline so I've had to do a quick fix involving some additional washers to fill the space. Not ideal, but I'm guessing that the course will handle flat and muddy and good set of front blocks should do the job. No time to consider tyres either, but this set haven't let me down thus far.
