If you're looking for an affordable road pedal that's light and stable, with adjustable release tension, the Mavic Race Pedals are worth investigating. They're very similar to Mavic's pro-level Race SL Ti pedals, but they substitute Cro-Moly for titanium in the spindle, and composite for carbon fiber in the pedal body. These substitutions add a few grams but don't sacrifice any function.

The Race Pedal is constructed mainly of aluminum, with a composite retention assembly. There's also a composite plate where the forefoot lands for a reliable connection between the cleat and pedal. You'll notice the substantial width of that cleat/pedal interface -- this is Mavic's Energy Transfer System, which ensures that the sum of your power is directed to the drivetrain. Additionally, Mavic uses only high-quality cartridge and needle bearings for its pedals to ensure that drag is kept to a minimum throughout the lifetime of the bearings, which should be a long time due to their sealed design. Even if the bearings do wear out, the Race Pedals are completely serviceable.

The Mavic Race Pedals feature tension adjustment via a 3mm hex screw. Mavic pedals use a triangular cleat similar to those used by other manufacturers. However, Mavic's 'DuraCleat' has strategically placed wear-resistant zones so that your coffee shop treks and unexpected hike-a-bike sessions don't erode your ability to clip in securely and mash with confidence. These pedals come with cleats that allow for 7 degrees of angular float, but 0-degree float cleats are available.
