Shimano SH51 Single Release Pedal Cleat and Cleat Nut

Pedal Power

Advantages: Perfect for sporting or casual use.
Disadvantages: None

the mechanism, and an outward movement of the heel to release it. The problem tackled by Shimano in the late 1980's, was how to have a shoe with a cleat bolted to the sole, which could also allow the owner to walk on the path !? The firm's solution is a smaller cleat which is bolted to a recess in the shoe and acts as part of the shoe tread when walking rather than cycling. So was invented the SPD - the Shimano Pedalling Dynamics - worth explaining because SPD can stand for all sorts of other things too.! 3 The Pedal Itself These pedals are beautifully light - less than 200 grams of aluminium each, and finished in an alloy colour that matches Shimano's other bike parts. They are easily fitted - the only tool needed being a crank spanner which is easily and cheaply obtained in any bike shop. They are marked as right and left, and that is ...

Review of Shimano A530 SPD Single Sided Touring Pedals

The Shimano M520 is an excellent all round SPD pedal!!

Advantages: Ease of use, Ease of installation, Versatile, Recessed MTB style cleats, Aesthetically pleasing!
Disadvantages: For road cycling the pedals are slightly heavier than more expensive alternatives

I recently purchased a set of Shimano M520 SPD pedals for my road bike. Although they are technically mountain bike pedals, I much prefer the Shimano cleats supplied with mountain biking shoes, which are recessed and hence make the shoes a lot easier to walk in! After installing the pedals on my bike (which took no more than five minutes) and fixing the supplied cleats to my Shimano SPD shoes, I was ready to ride. The pedals give you the option to adjust the tension in the clips however I found that they worked fine straight out of the box!! One thing I like about these pedals is the ease in which you can clip in and out. With clips on both sides there is no hassle trying to flip the pedal over, and you simple need to place your shoe anywhere near the correct position and its really easy to clip in! For the price these pedals are ...

Review of Shimano PD-M520 Click Pedal

Outstanding Budget Pedal from the Big S

Advantages: Impressive durability, adjustibility, reliable SPD mechanism
Disadvantages: Mud clearing not as good as other brands

cleat. On the pedal mechanism there is a screw with marker arrows, so you can adjust the clip tension. Shimano also sell multi-release cleats, but you don't need them. A standard cleat is supposed to only release when you twist your heel outwards on the pedal, whereas the multi release cleats will also release if you rotate your foot. However you can achieve a similar effect by carefully adjusting the tension. Mine is set loose so that it will hold the shoe in under normal pedalling pressure, but if I pull up hard then the cleat will disengage. The downside is that there is now some play between the cleat and the clip, however I have always separated from my bike in any of the spills that I have had. And this safety benefit alone more than outweighs the slight clicking that I occasionally get on the upstroke. It is relatively easy to ...
