- info · this part aloneFactor OSTRO VAM Fork has a 1-3/8in (37mm) lower steerer. This catalog lists complete headsets only, and none of them is built for that seat, so no cataloged headset will show as compatible - frames on this steerer are serviced with bearing kits rather than with a complete headset.
