This pedal pin kit contains 20 sets of bolts/nuts for your Raceface Chester pedals. This pack is enough for 1 pedal to fully replace the pins. You've got 16 pins per pedal so you'll have a few spares. Hopefully you don't need to use all of the pins! If you're replacing all of the pins for both pedals pick up 2 packs of these and you'll be left with some spares.
