When I bought this bike 10 years ago it had a standard crank with 52/39 and a 25 out back. I rode it like that for a while and it was fine for rolling hills and small climbs. Even did some club rides in the 70 mile range. But I go into the mountains a lot and I have to have lower so I had to change the crankset and the cassette.
