Shimano’s PD R550 SPD-SL pedals may hover around the bottom of Shimano’s pedal pecking order, but that doesn’t mean they’re not good quality. In fact, they offer excellent value for money with their sturdiness and ease of use.
It’s a pretty standard setup, with the pedals attaching to your bike via pedal spanner or 6mm allen key. Although it’s worth bearing in mind that Shimano stresses you can’t reach the necessary levels of torque (Shimano recommends 35 – 55 N-m) through just an allen key, necessitating the use of a pedal spanner.
Once they’re on, spring tension is dead easy to adjust, and by using an 2.5mm allen key you turn the screw either left or right to tighten or loosen the action depending on what you’re comfortable with. If you’re not sure, it’s always worth getting some advice on setting up cleat and pedals, so you don’t end up give yourself knee pain, or being unable to release from the system.
