The Time Xpresso 4 pedal shares the same iClic technology of the Xpresso 6, has the same solid steel spindle, and further saves you money with a different composite body. A carbon fiber leaf spring handle tensioning duties, unlike steel coil springs found in most pedals.
The Xpresso pedal line boasts the fastest engagement time of any pedal, anywhere. The Xpresso pedal rests in an open position, so you don't have to overcome any spring tension to open the pedal and lock your cleat in. When you twist your foot to click out, the engagement mechanism stays open until you step back in—effortlessly.
You invest in the best hub, chainrings, cassette, and chain for the fastest response possible from your bike, why sell yourself short on your pedals? Get the worlds fastest pedals, Time Xpresso's.
