Not sure if this is the correct place to post this so please tell me where to go should this be inappropriate. I have been riding on Ritchie clipless for many years and they are aging. This was brought forcibly to my attention a week or so ago when my right pedal refused to let go as I was coming to a halt and leaning to the right. No need to go into details. If it had not been for a small piece of broken off tree that decided to examine my thigh muscle closely it would have been better, but no matter.

The pedals I think have done their duty well and it is time for something new. My shoes are in excellent condition so I want to reuse them with new, and compatible, cleats.

I see that Shimano make two types of pedal that are clipless on one side and have a regular pedal on the other, I think this might suit me very well for my Moulton. I use the Moulton for commuting and for just buzzing around on, and if I could do this latter with whatever shoes I was wearing at the time I would probably use it even more.

Does anyone have any experience with these pedals? Specifically, as they are one sided, it is hard to get the right side when using the cleated shoes? With the Ritchies I can feel my way into them very quickly, is this possible with the one sided pedals?

Also, which would be the best of the two? They are the PD-M324 and the PD-M545 I think. I would not be doing any off-road so the latter is probably overkill.

Also, I have a Campagnolo Mondia. Would the cleats be compatible with other Shimano pedals more appropriate for the Mondia?
