All current LOOK binding pedals for road use are unified into the KEO series.
Within the KEO series, they are divided into the following three grades.
In addition, within each grade, there are several variations such as “CARBON” and “PLUS” with different materials.
The grading system is not as simple as Shimano’s binding pedals for road use, but it is good to remember that they are “BLADE, MAX, and CLASSIC”.
The KEO BLADE is the top grade of LOOK’s current binding pedals, with the name of the base model followed by the name of the part material.
All models are made of carbon, so the base model is “KEO BLADE CARBON”, which is divided into three models according to the materials used for the bearings and shafts.
The KEO 2 MAX is one grade below the top-of-the-line KEO BLADE, which is a binding pedal with a completely different structure and shape from the KEO BLADE, similar to Shimano’s SPD-SL pedal series.
The KEO 2 MAX is available in two models, a carbon model and a regular model, and they look almost the same, but you can tell the carbon model from the regular model because the body color of the carbon model is slightly more carbon.
Among LOOK’s binding pedals, the KEO 3 CLASSIC is the comfort model, based on the higher-end KEO 2 MAX model, but with a simplified body structure for a much lower cost.
The KEO 3 CLASSIC is the base model, and the PLUS has a stainless steel plate for the crate contact surface.
The upper grade KEO BLADE and the middle grade KEO 2 MAX are all different in shape and structure.
The KEO BLADE, while inheriting the previous LOOK series, uses a bottom plate structure similar to TIME, designed to better convert pedaling power into propulsive force.
In terms of weight, the KEO BLADE is as light as the TIME pedals, which are known as lightweight pedals, while the KEO 2 MAX series is about the same as Shimano’s SPD-SL pedals.
As explained earlier, KEO 3 CLASSIC is a lower-priced version of KEO 2 MAX, so it is a line for those who want to try LOOK binding pedals at a reasonable price.
If you want to enjoy serious riding, such as long rides or road races, it is better to choose KEO 2 MAX or higher.
However, the KEO 3 CLASSIC is priced lower than Shimano’s entry-level PD-R550 road pedal and is about 10% lighter (PR-R550 is 310g/pair), so beginners who want a lighter pedal from the start may want to choose the KEO 3 CLASSIC.
model | series | weight (pair) | shaft | bearing | body | bottom plate |
---|---|---|---|---|---|---|
KEO BLADE CARBON CERAMIC TI | KEO BLADE | 190g | titanium | ceramic | carbon | Available |
KEO BLADE CARBON CERAMIC | KEO BLADE | 220g | Chromoly | Ceramic | Carbon | Available |
KEO BLADE CARBON | KEO BLADE | 230g | Chromoly | Steel | Carbon | Available |
KEO 2 MAX CARBON | KEO 2 MAX | 250g | Cromoly | Steel | Carbon | None |
KEO 2 MAX | KEO 2 MAX | 260g | Cromoly | Steel | Composite Body | None |
KEO 3 CLASSIC | KEO 3 CLASSIC | 280g | Cromoly | Steel | Composite Body | None |
KEO 3 CLASSIC PLUS | KEO 3 CLASSIC | 280g | Cromoly | Steel | Composite Body | None |
There is a 100g difference in weight between the entry-level KEO 3 CLASSIC and the top-level KEO BLADE CARBON CERAMIC TI, so it is worth choosing the KEO BLADE CARBON CERAMIC TI even if it costs more if you are concerned about weight reduction.
The KEO 2 MAX CARBON is a well-balanced model for those who want to save weight.
All current models of LOOK binding pedals are compatible with KEO cleats, so they are not compatible with DELTA cleats for older models.
Note that although KEO cleats and DELTA cleats are similar in shape, they are not interchangeable and cannot be used interchangeably.
