Bearing more than a passing resemblance to a Wilier Triestina Ramata this copper-orange cromovelato Obiso branded road frame is small but perfectly formed. Obiso is a long standing bicycle shop located in Rome, and legend has it that Vetta built frames for them (a quick browse of their website will bring up some great photos of their Ciclo Obisio-Canon cycling team). The cut-out lugs, Columbus branded seat stay caps and fork crown, alongside the lightened BB shell and a finish of the highest standard certainly make this plausible. Once you get past the stunning coppery-orange-lacquer-over-chrome paint job, the most intriguing feature of this frame is the indented seat tube combined with vertical Campagnolo dropouts to really tuck the wheelbase in, the low overall weight adds to the impression that this frame was designed to go fast, most likely a time trial machine. This one really is up there with Italy's finest, Vetta built or not, it's a wonderful example of a thoroughbred race frame begging to be built back up with a top-end Italian groupset and ridden fast, just as God (or Vetta) intended.

If you're taking part in L'Eroica or a similar vintage event, this frame is of the correct age, so you won't be disqualified for being a rule breaker!

The frame's been carefully checked by one of our mechanics to confirm the alignment's correct and there's no damage to the threads. If there are any minor issues worth noting we will do so in the overview section below. Please take a good look at the detailed photos so you can see the cosmetic condition of the frame before you buy.
