I put a set of Shimano M324 Pedals on my Gary Fisher Mtn bike. I got the SH-56 Clips. I was scared at first thinking I'd not be able to unclip and fall over

I like the different releases of the SH-56. I will probably install these on my Trek 1.5T also. I love being able to use my bike shoes or just plain sneakers with them. I can really feel the difference on the steep uphills being able to lift with the other leg. When I'm in heavy stop and go traffic, I unclip and use the other side of the pedals.

Best of both worlds!

I opted for the Mtb type shoe. The street shoes just did not fit my feet well.
