I ve been riding with that Crankbrother style pedal and recently decided to try a Keo style pedal on my bike,
I already had the road shoes and had tried a different Look pedal with the delta clips didn't care for them at all ,So i ordered a KEO clone
pedal and it is much better for me, I like the way it feels (red CLips) its almost like no clips at all until you stop I did losen up the hold down for a while till I am sure I can easily unclip. I have the clip covers for walking about thats a big plus my new cleats came with covers.
The pedal distributes your energy better, your legs feel more springy very pleased.
