I have a Suntour Superbe rear d and pedals on my vintage Trek road bike. Amazing stuff. The best part is my uncle just had the parts lying around and gave them to me, along with perfect Campy dt shifters, fr d and some other random bits. Its a bit of a mutt, but it rides as nice as just alot of new bikes, is an average of 20 years older, and was set up for under 100 bucks out of pocket.
