I was wondering what cleat standard is compatible with the Peloton Trainer ?
What cleat standard is installed in the default configuration ?
According to https://www.onepeloton.com/shop/bike
The Peloton Bike uses LOOK Delta clip-in pedals, so you’ll need a pair of compatible cycling shoes to ride.
However the images show standard bike pedals with 9/16" standard threads. You should be able to fit whatever pedals you like.
Actually, IT DEPENDS. Peloton sells a home version that uses LOOK and a commercial version (to most hotels and apartment buildings) that cannot use a LOOK but that have a shoe-cage on one side and an SPD SH51 clip on the other side. Most Peloton reps do not seem to know this (for all the money they charge you think the company would train its people...) so check your bike carefully. It might be easier to take a picture of the bike pedal and bring it to the bike store so you don't accidentally buy the wrong clips--or shoes. (Not all shoes take SPD and LOOK, many only take one type or the other.)
