I have asked before, but I am still not sure. I have this Raleigh "Routier" I know that it is not and never was a classic, or even a good bicycle. But.. It is now all nice and proper and ready to roll. Except..The back wheel kicks out, whenever I put any "power" down. I have tightened the QR's as hard as I can. Is it possible that it originally had 27" wheels and not QR's but old-style axles?
