Fox 34 fork cargo cage mounting clamp (TPU)

thingiverse

This is a clamp designed to attach bottle cages or cargo cages to the legs of a Fox 34 fork. The cages attach to the same M5 bolt that is used for clamping for simplicity. The mount is intended to be printed from TPU flex filament with ~80% infill, which can compress around the fork to prevent slipping. This material is incredibly tough, but two pieces of aluminium plate required to distribute the clamping forces and constrain the bolts to prevent the TPU from over-stretching. These plates can be easily cut and drilled from 20x1.8mm aluminium bar stock. The following parts are required to hold one cargo cage: - 4x clamp halves - 4x aluminium plates - 8x M5 washers - 4x M5x70mm bolts - 4x M5 lock nuts. Installation: - Wrap a layer of tape on the fork to protect against rubbing - Assemble the clamp components as per the attached image, placing the cage between the aluminium plate and the washer on the bolt head side. - Tighten the bolts until the TPU starts to deform around the fork. The clamp may still wiggle slighly as the TPU compresses further, but this will actually help to absorb impacts. It should not shift. Warning: I designed the mount such that the bolts or clamp components could not interfere with my spokes even if the mount slipped and rotated. Make sure that you check this for your wheel.
