I have recently bought some shimano bike shoes and am thinking of getting some shimano m520 pedals.. http://www.cyclesportsuk.co.uk/product_info.php?products_id=936&cPath=198 The one things that concerns me is when starting off at a road junction or traffic lights. The type where i can't mess around trying to clip in. Using my toe clip current pedals i would just ride with the pedal upside down and then clip in when i had gathered some speed. I'm not sure i can do that with the 520 pedals tho. I suppose i could go for a normal type pedal that takes clipless like the 647 but i was thinking the 520s would be better for a road bike Any advice??
