I have a pair of these for sale if anyone wants to give them a try. £40 posted.
They are virtually brand new. I tried them for 12 miles but decided to stick with my SPD's. As advertised, they are light and the grippy stuff is really grippy, they are slightly revolutionary in appearance but didn't look out of the way on my Thorn Raven Tour. I had hoped that they would offer me the same benefits as SPD's but with a choice of footwear.
I have decided not to keep them as, after long term SPD use my pedalling style means that I tend to lose contact with them on the up-stroke.
