Shimano calls the M424 an off-road sport pedal. We agree, but think the M424 can also be used on an urban/commuter bike as well. Each pedal is designed for easy clip-in and extra stability, with a spring-loaded platform that automatically position the pedal at the perfect angle for clipping in. The intuitive operation makes this pedal particularly well suited to city riders that need to clip in and out at a moment's notice, along with aggressive mountain bike riders tackling technical terrain. The platform also offers greater stability than other pedals, and can be ridden without special shoes for impromptu jaunts to the grocery store. The pedals come with a single pair of two-bolt SPD cleats.
I'll agree with other posters that these are great for beginners and "recreational" riders. It's nice to have a platform if I'm not having to lock in. Cleats and instructions included and easy to install. So far so good.
I have used these pedals for a couple of years now, and they work great. My cleats always engage with them right away, and they are easily adjustable.
These came with the SM-SH51 cleats & instructions for getting everything setup. They were easy to install & adjust the bindings so they were not too tight. I like that they have a platform which allows for easy pedaling in street shoes. However, at times I am unable to clip in as quickly as I like & I believe the tread on my shoes may be interfering some with the cage around the clip of the pedal. Overall, a great beginner pedal if your bike is multi-use.
