This is an incredible bike to ride. The frame is a 1971 P-15 touring Paramount frame with a slightly longer wheelbase than the P-10 or P-13 road bikes. Take the big chainring off, decrease the gear options, and increase the challenge. In today's world of 20-30 speed road bikes, this is the one I love to ride! Since no gear is ever perfect or enuf, therein lies the challenge!
