OK, I am getting a picture of how useful these pedals can be in MtB rides... but I still wonder about being on the road and having your legs working in different ways (given that with cleats you can pull up a little)... do these pedals work at speed, or is it better like Cruzie's sister uses them, at slower speeds in town?
I just find the whole idea fascinating, though it doesn't appeal to me to try. i think I'd confuse myself.
