Damn sellers (in this case a consignment shop) who sell bikes and don't know squat about them!
This bike purports to be a 1940 Schwinn Paramount track bike but when I try and find out some basic info and measurements I get the response: Im sorry, this bike is assembled and we can not take it apart to count the teeth or to measure the tubes. We are selling this item for someone. Thanks for your interest
Ebay item number 6529436553
Of course no relation to seller, etc. Bike located in Kenosha, Wisconsin...
