This is a 1920's bike. It is labeled as a Fossati but it is most definitely not a Fossati as they did not exist at the time this bike was made. It is a 63 cm frame. Note that there is no brake bridge between the seatstays. The seatstays are also simply bolted on at both the top and bottom. The chain is an inch, skip-tooth or 'Humber' pitch chain. The rims are original wood rims. Steven Maasland - stevenmaasland@comcast.net
