Similarly to the pictured below RS Pike, most fork manufacturers place the ark in front of the stanchions. This has proven to be a terrible solution when riding in muddy (or actually anything different than asphalt) conditions:
- on each rotation, the tire grabs some mud, dust, sand
- the first (and only) thing, standing in the way of the accumulated muck, is the fork brace
- the brace scrapes the mud
- the mud accumulates on the conveniently located flat areas behind the brace
- the stanchions work to push the contaminants into the bushings and seals
- the mud builds up indefinitely, instead of just falling to the ground
Why not place the ark to the rear of the stanchions, like DT Swiss do?
