These pedals go back a long way; I bought them second-hand in the mid-90's! They probably came with a bike, but I can't really remember. Each pedal has a small allen bolt, that allows the tension to be adjusted.
My name is John Swindells and I'm a keen recreational cyclist with a preference for long one-day rides. I've also previously dabbled in time trialling and cyclo-cross. See more of what I get up to on Strava!
