I just saw this new “experimental” frame from the folks at Bikesdirect / Bikeisland. They added a second top tube to their popular Kilo TT bike frame, and widened the front fork and rear triangle to accept 700×38 wheels. It’s based on the vintage designs of the early 20th century, sometimes referred to as “scorchers.”
Looks like a lot of fun to ride offroad, in the snow, etc. Or perhaps re-paint it and make a modern-retro townie to match your tweed jackets. It should be available for sale by the end of this week, a limited run of full bikes at Bikesdirect for $450 and framesets for $250 at BikeIsland. Sizes available are Small – 53c C-T, Medium – 56c C-T, and Large – 59c C-T.
