I have a suspicion that were I to contact Tubus or Axiom I would learn there probably is no standard placement for a mid-fork eyelet and that all the rack manufacturers can do is provide parts to adapt (Axiom did not). The Roswheel design has a lot of adjustment possibilities with parts they provide. I seemingly got lucky and am happy with how it installs and the quality of the rack.
They are a UK company, I had no clue they existed, saw the rack on the Universal Cycles site, found I could order direct, DHL had it to me in 3 days. Roswheel makes a lot of bags as well, good looking stuff. Not terribly priced and if I hadn't had a very large gift card at REI I might have purchased from them instead of Ortelib.
