Sorry...its a Frontiera lol...Reynolds 753 frame though made or renovated about 1987? for a Martin Smith, his name is on the bb, frame no 3059 I think from a bicycle shop in Carlisle Cumbria. Sorry not an exotic Italian machine but saying that from a very nice part of England.Now tell us more about the bike! Bianchi?
Thank you....if I'm to be honest the only real frame I would like just to say I owned one is a sbdu 753 or 531sl.Better than a Bianchi!
Thanks HammyStart in the middle hole. If it bottoms out, go to the lower, if the return is too weak, use the upper.
