“PowerCranks have come to my attention… and I see them … as a very good training aid… talked with Bjarne Riis … and he is very positive about the riders using your powercranks.”
Scott Sunderland, ex pro road cyclist
Sports Director for the "CSC Professional Cycling Team"

“PowerCranks are a very valuable tool... Something that forces everyone, pro’s and amateurs alike, to be more efficient by forcing you to carry the weight of the up stroke leg and also maintain force through the entire range of motion...It’s something that nothing else forces you to do and it makes you do work that is without a doubt of benefit.”
Dr. Max Testa, doctor for the, 7-Eleven, Motorola, Mapei & MG-Technogym cycling teams. Co-founder of the UC Davis Sports Performance Lab

"My clients have made great gains in efficiency using PowerCranks.  Their pedal stroke improves by 10% when assessed with the Computrainer.  I recommend them for cyclists and triathletes!"
