Only at Crank Cycling/Aire With the unfortunate closing of San Diego Coastal Sports Medicine enter, Crank Cycling now has the only Multi Rider Computrainer System in San Diego. We are still developing our Computrainer program, and will be adding more Computrainer classes soon. Keep an eye out for Saturday Computrainer classes to be added in the very near future. We are creating a special email list for those of you that are interested in Computrainer classes. If you want to stay in the loop on these classes, just fill in your email below. Want the most current Computrainer schedule? Check it out here.
