Ive got some fitted to my bike, as Jez says, the part that you foot sits on is shorter and is actually further out than standard. I find myself riding with half my foot on the peg and half on the inside "adjustable" bit, which means my foot sits at an angle, but it doesn't bother me. Ive just come back from Belgium with no probs as far as knees go, and I haven't got the best knees in the world. But I think im going to have a softer seat, its the arse that goes first. Any suggestions as to who could modify the seat foam?
