Platform pedals provide a great way for mountain bikers and casual city or trekking cyclists to enjoy their bikes without being 'clipped in' to the pedals. Platform pedals provide grip through the use of replaceable pins, like these PD-X09 spare pins from XLC. Whether your pedal’s old pins are a bit past their best, or you lost one in the middle of a ride, you can replace the pins on any of the following XLC pedals with this product: PD-M09 / M12 / M14 / M19 / M20 / M21. The pack includes 52 pins, enough to keep you going for quite some time. They are made with steel and the dimensions are M4 x 7.5mm long.
