Ron Kiefel finished six out of seven of his Tour de France tries, won a bronze medal in the 1984 Olympics for a team time trial and has probably ridden more than 300,000 miles during his cycling career -- which makes him especially suited to understand all the nuances of riding bicycles. Kiefel believes getting a custom bicycle fitting is important for anyone who is serious about cycling: With the right frame, a cyclist can ride better, faster and longer. Ron and the twelve other certified bicycle fitters who work at Wheat Ridge Cyclery choose a frame best suited for your frame, and with over 1,000 bicycles in stock, it's not hard to find a fit.
