Xpress Execute XM1 flat spot suspension pins
Xpress have introduced new 3x18mm flat spot suspension pins for the Execute XM1 kit. The shafts, used on the front C-hubs and rear uprights, feature a flat spot that, in combination with the standard grub screw, greatly reduces the chance of the pins coming loose or working their way out during racing action. The pins come in sets of four and they are available now.
