The Look Keo Blade pedals, with their large contact surface and spring-less engagement mechanism, are Look's top-of-the-line performer in the Keo pedal lineup.
Look invented the clipless pedal in the early 80s based on equipment for ski bindings, and they've become a staple of modern road cycling.
Look pedals offer a single-sided interface and three-bolt design to attach the cleat to your cycling shoes. Look cleats offer three float options with a fixed position black cleat, 4.5 degree gray cleat, and 9 degree red cleat. Look pedals are easy to use with easy engagement and predictable release, making them appropriate for new cyclists while still offering performance options for the bike racer and competitive triathlete.
The Look Keo Blade pedals have a lightweight carbon body and a 60 mm wide, 400 square millimeter stainless steel contact surface. The Keo Blade is just 120 grams per pedal.
The Keo Blade Carbon option boosts the contact surface to 67 mm wide, 700 square millimeters stainless steel contact surface and trims weight down to 110 grams per pedal. And for those looking for the lightest option, the Keo Blade Carbon offers a titanium axle version that gets down to just 95 grams per pedal.
The Keo Blade doesn't use spring tension like the Keo Classic 3 and the Keo 2 Max. Instead, it uses a blade, seen under the pedal, which flexes when the rider engages the cleat. This allows for weight savings and the integration of the blade into the pedal body means the pedals are more aerodynamically shaped.
You can buy the Keo Blade in two tension options, an 8 Newton-meter for easier engagement and disengagement and a 12 Newton-meter option for riders looking for a more secure hold. The more expensive Keo Blade Carbon offers three tension options - 12, 16, and 20.
The Look Keo Blade is ideal for the cyclist that prefers the ease-of-use of the Look Keo pedal range and wants to trim weight and maximize performance.
Blade technology uses a blade instead of a conventional metal spring, which has many advantages for the user:
- Safe cleat entry/ release: the blade flexes, providing a firm hold once clipped-in, and when clipping-out, releases the foot faster at the end of the process in a quick and secure movement.
- An aerodynamic shape: thanks to the integration of the blade inside the body, pedals equipped with BLADE technology have the best aerodynamic shape ever created.
- Low weight: the design of the pedal around a blade system allows a significant reduction in weight and better load distribution.
SPINDLE : MORE STABILITY AND BETTER LOAD DISTRIBUTION
The Blade Carbon pedal spindle was designed to obtain a very low stack height: only 13mm. It uses a needle bearing cartridge installed in a central position for better stress resistance while pedaling and two spaced out ball bearings which distribute the load, providing increased rigidity between the body and the length of the spindle guaranteeing excellent rotational speed.
Axle play (related to internal bearing movement and part wear) is eliminated by a wave spring that constantly applies a pre-load that does not deteriorate over time. When pushing hard on the pedals, this system can completely eliminate the annoyances caused by any play (noise and sensation of friction ).
LOOK axles are only approved after a rotational test of 2 million cycles at 100 rpm with a load of 90 kg on the center of the pedal and an eccentric rotation (which creates stress on each revolution). This is equivalent to a sprint by André GREIPEL of 1700 watts at 100 rpm for 333 hours! This test is much more demanding than the current standard, the ISO 4210.
