Connor Keating signature pedals. The Turbo pedal has a unique body shape that covers the end of the axle giving a near-flush connection to the crank arm. This allows you to have much more foot placement freedom when standing on the pedal, as well as more grip, an improved surface contact area for modern day crank arm grinds, and an all-around more aesthetically pleasing appearance. The pedal can be tightened via an Allen bolt on the backside of the spindle and also allows for the use of a thin Park Tool-style pedal wrench. 9/16″. Sold in pairs.
