We made these handy plates for use with our Long Haul or Disc Trucker frames, and only our Long Haul and Disc Trucker frames! They are to be used with a bicycle kickstand to keep your bicycle upright while not moving as if by magic. The plates consist of two halves that, when clamped on your frame in conjunction with a kickstand, protect your chainstays from being hamfisted by sandwiching the frame between the plates. Have you ever eaten a hamfest sandwich? They taste terrible, so avoid them like the plague.
