Not convex. Not concave. This is Wave. Shaped like a wave, our new pedals are tall at the front and slopedtowards the back. This promotes an aggressive heels-dropped ridingposition and gives you a more natural pedal stroke when seated. Shape Wave works with the shape of your foot to give you more controland more grip from the pedal, not just the pins.The concave front half of the pedal hugs the ball of your foot,holding it securely in place on rough descents.The convex back half of the pedal is sloped down, giving you anaggressive heels-down riding position for more power and control. Construction Wave pedals feature a fully redesigned axle, bearing and bushinglayout which is reliable and easy to service.They also feature fully threaded 'hollow-hex' pins that are angledforward up to 10 degrees to increase grip while riding and furtheremphasize the Wave shape.Every pair of Wave pedals comes with our Bearing Nut Tool anduses the same rebuild kit as our Clip Pedals - making serviceparts easy to stock. The OneUp Pedal Lineup Wave pedals offer increased grip, feature self-clearing hollow-hexpins and are an innovative new design. They expand our alloy pedallineup and will be available alongside our original Aluminum Pedals.
