Shimano PD-M424 SPD Pedal
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.
Let me first say this. If you live and ride in an area that gets mud, thick, sticky dirt, and loam: don't buy these pedals. Their mud-shedding ability is next to none and if you even so much as put your foot down while riding in these conditions, expect to spend a while smacking crud off your shoes and pedals before getting back to riding. With that out of the way, and if you live and ride in dryer conditions, these pedals are pretty darn good! The mechanism is very smooth in and out, the plastic cage provides good protection to the mechanism from rock strikes and ample support if you need to unclip or ride somewhere in regular shoes, and the plastic doesn't add much weight. It can start squeaking when dust gets in, so make sure to keep these clean. They're pretty durable and reliable as well! However, I don't think these pedals are going to be your best choice. As mentioned earlier, they're awful in wet, muddy, and loamy conditions as they clog very easily, they're heavy, they're expensive, and there are better-performing pedals out there for less money: such as shimano's own M530 pedal.
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.
