Just picked up this Raleigh Grand Prix. I believe it is a '77. It had sat for many years and looked to be original except it had no wheels. Seller said he'd include a set of alloy wheels and tires. I dissasembled and cleaned and lubed all the bearings and brought it back to life. I figured it would make a decent spare bike for guests. And at $50 I figured it was a good buy. Is there any drawback to riding on wide tires (700X38)? And is there any shame in a man riding a lady's bike?
