Durable, grippy plastic platform pedals built for commuting. Pedals are one of the three key contact points with your bike. Theyre just as important as a good saddle and good grips in making your bike comfortable, controllable and efficient. Good pedals add speed and efficiency to every single pedal stroke. Standard road and mountain bikes use the 9/16" thread featured on these pedals. The steel axle and ball bearings give great reliability. The PVC platform is grippier in the wet than old-school metal pedals and wont scuff up your shoes or shins. They feature reflectors for visibility. The pedals are marked as right and left to suit the standard/clockwise (right-hand) and reverse/counterclockwise (left-hand) threads found on all conventional cranks.
