Akront is/was a Spanish rim and wheel maker long famous for motorcycle rims but they also made some bicycle rims, too, tho I have never seen any of those in person. I recall seeing pix of some alloy tubular rims (sewups) with Akront decals or stamping, and think these were pretty early vintage, maybe 1970s (?) maybe even earlier. Akront is no longer in business but the tooling was acquired by Morad, another Spanish motorcycle rim maker and they continue to build rims with the same Akront spec. or so says the interwebs.
