To us who rides different bikes theres no better feeling than in a well taken care of vintage bike. I do longer sportives (and been riding for quite a while) and I cant say a new bike could make me any better. A vintage bike/frame of right brand were indeed engineered to enhance riding, and the extra weight (compared to newer bikes) will only make you strong. An older frame can be built up as you get into the sport. If you dont get into it, IŽm sure youŽll get your money back flippinŽit. New bikes has comfort, but wont beat the feeling of a true vintage.
