I have finished building my cheap bike rack...
I wanted to use my Thule accessoires... so the X-Tower where out...
I have used Mighty Mounts 28H from Yakima, some aluminium square rod from home depot and some old Thule bars (cut at 32 inches, to be narrower than the X-Terra rack)
The yellow mark is around a long bolt going through the thule bar, the aluminium bar and bolted in the Mighty Mount. The red mark is the Mighty Mount.
The bike is held by a fork adaptor bolted diretly to the thule bar.
