Thank You.Ive been searching the web and really haven't found any data on this bike. I did find a data base on Shimano Dara Ace. And I'm thinking components are 7100 set.And hubs are different but, rims have same sticker which I can only identify 27x1 1/4.Any ideas on rims.Thank You on your help and knowledge of bikes.Be Safe out there.Its still a car world.
