Wittson Cycles is a Lithuanian handmade bicycle manufacturer located in KlaipÄ—da. Wittson works exclusively with titanium and sources the European Grade 9 tubes from Baltic neighbor Sweden and the VSMPO Titan Scandinavia corporation, which also supplies aerospace luminaries Boeing and Airbus. Wittson uses 3/2.5 Ti for their frame production, and 6/4 Ti, which has greater tensile strength but is much harder to weld, for dropouts and bottom bracket shells, along with smaller bits such as brake cable stops.
