i just got these today



Shimano M520 SPD Pedals & Shimano MO38 Shoes

First time on clipless, I was worried and thought I wouldn't ride it(clipped) home after installing in the shop. but i tested it on a trainer in the shop, clipping in and out couple of times and thought it was OK, and i rode home no probs.

Overall it's good, a plus to efficiency. I reckon it needs to conform with the saddle's height, which the good mechanic in the LBS adjusted perfectly for me, to be able to clip-in-and-out better and the pedalling is much smoother.
