I have a 1993 Bridgestone XO-2 53cm 26" wheeled road bike. Fell from the sky into my lap. All original with seat, tires, chain, bar wrap, cables and housing all shot. Looks like it was ridden very little and time alone has deteriorated these components. Not my size bought to resell so should I replace with high end parts (that the bike deserves), cheap parts, or do nothing and let the new owner set it up as they wish. What would you do?
