MSW Co2 Cartridge Box (100 Pack)

What is the difference between a KEO CLASSIC 3 and a KEO CLASSIC 3 PLUS? The material used for the contact area. The little extra, stainless steel rather than composite, optimizes pedal stiffness and hence the transfer of power from you to your bike. As for the rest, Look Cycle USA sticks to what works: fast clip in / clip out and easy tension adjustment.
