Hoping you lot are waaay more practical than me! I'm planning a bike race for next year, and the course has to go over a couple of slightly raised curbs (about 1.5"). Anyone got any idea how I could 'ramp' it so the bikes smoothly sail over it? Was suggested coal tar, but the estates people said the curb is too small so they wouldn't be able to make a nice ramp on it, so it would just break up. Any kind of small rubber ramp or something?
