I raced in the 50s on 27" TUBS, Dunlop made tubs in 26" AND 27" size, I sold to a list member a pair of Dunlop #3s NOS that where clearly marked 27" I did try them on 700c rims and they did fit OK but a little loose, I dont think I would have wanted to glue them on a700c rim they in my mind would have stretched, NOW since in the USA I have NEVER seen a 27" Tub Sew up rim! for that matter I have never seen a 26" also, Would a 26" Dunlop tub fit a 700c rim? Alexander VonTutscheck "Fancy Lugs" told me at a LeCircque that NO 27" Tub SEW UP rims where made? they where all 700C BUT I do remember that I had Brit made tub rims in a 27" size! WHERE ARE THEY NOW! I have never seen a pair on Brit or US Ebay for sale. Only the 700c. How about an answer to my question WHEN DID BRITS stop using 40 32 holes and go to 36 and WHY? It has always seemed to me to have more spokes in the back wheel than the front,made sense. why did others use 36x36 the cost and the work to lace would have been the same the weight is the same, You big blokes would be safer with more spokes in the back wheel I would think, SO why 36x36? did Great Britain cave in once again to other country's! TRADITION Chaps, Have a PINT or should it be. have a .473 litres on me at the local. Cheers John Crump OldneedapintnowBrit, Parker, Co USA
