Clipless cycling pedals, shoes, and cleats are the three names revolving around advanced biking. However, other than using clipless cleats and shoes, you have to consider that there are different clipless pedal designs. Even better, understand that clipless pedal compatibility with shoes and cleats is not apparent.
Among the most popular clipless pedal designs are Delta and SPD, yet the two are so different that their accessories are not compatible.
As a whole, SPD cleats are two-hole, while Delta cleats are three-hole designs. Delta is better for power transfer than Spd. On the other hand, spd is easy to clip in and out than delta. You can walk with spd shoes, but it’s hard to walk with delta.
And there is more to this, so let’s dig into the details.
What is Look Delta?
Look Delta is a clipless pedal and cleat combination usually preferred for road bikes and indoor spinning bikes. The cleats have a signature 3-hole design, differentiating them from its greatest competitor, the SPD pedal and cleat system.
It is more convenient, with a wider contact surface and wider compatibility. They are also more convenient, with a memory positioner that facilitates ease in changing cleats.
Furthermore, the design is the most comfortable of Look’s creations. It also allows for rotational movement inside and outside for easy disengagement, hence a safer option.
It has also regained popularity from its use by the indoor spinning bike company, Peloton as a default pedal and cleat design.
What are the Benefits of Look Delta?
Basically, Look Delta is preferred for road cycling due to its high power transfer benefits. Its cycling shoes come with a rigid bottom, which couples with the three-hole cleats to offer excellent power transfer to the pedals, hence a more efficient ride. Also provide more secure foothold on the pedals.
Being the default Peloton pedal system makes it the best option for cycling Peloton, as one feels they are in line with the instructors and top-performing Peloton users.

Is Look Delta the Same as SPD-SL?

SPD is compatible with shoes whose cleat plate is designed for the two-hole SPD cleats, hence pedals.
Pros of SPD
- moderate float
- More shoe options
- You can walk in the shoes
- Easier to clip in and out
Cons of SPD
