Been here done this
tried:
510 and shimano shoes
1st pedal Xpedo ambix – clip one side flat the other
conclusion : clip was excellent, althoguh when weighted the spd mechanism didnt offer enough platform, causing discomfort in my foot, and allowing my foot to move too much (less gippier than a flat pedal). Flat pedal up was ok on grip, and flat side up was default orientation.
This pedal is now on my gravel bike. being sat down all the time it doesnt cause much issues, or i use the flat side a lot more as i dont need so much grip.
2nd pedal – Magped Enduro…. worked wuite well, mderate grip all the time, easy enough to magnetise in, and pop out.. didnt feel any significantly better than a flat pedal, might try stronger magnets in the future.
3rd pedal, DMR V Twin – true clipless pedal with platform support on both sides. Truly excellent, easy to clip in and bail out on, ive jumped over the bars and somehow unclipped before now. these are my go to when i want to ride in clips. much easier to get in and out of then a fixed mechanism.I believe the cheaper Shimano 5…. somethign or other have a floating mechanism also.
My personal conslusion from all my messing around..Ive got plenty of grip on flat pedals, i dont need to mess with it, exceptions as follows…
On the gravel bike just spinning for miles on end down the road.. being able to relax my foot somewhat is quite nice.
On the DMR pedals being able to get up over the bars and really push into a sprint, the clips shine.
neagtives to the clips i found, where you think you need them, hard climbs… is when i dont want them… that’s when i’m at walking speed, and if i suddenly slip on a root.. thats it. im stationary and stuck.. until im horizontal and stuck
