Just finished putting this bike back together.. It was -15 when I got up this morning and it warmed up to -6 now .. Curious on any information/comments on this.. I added the seat and the Delta Rooster light.. Was thinking about all white Reproduction tires.. I regreased all the bearings and they are super smooth.. Looking forward to riding this one** Is the rear rack correct? Date on the crank is 1920.. Can this be correct?
