I bought this fine old Crescent racer with Campa , 3ttt etc. Usual old-school lowlander gearing: small, compact freewheel and 54/45 chainrings. Proved a bit tough on some of our hills which, though not long can be pretty steep. So, I've changed the freewheel to a 14-24, and the small chainring to 42. Should I change the large one to 52 to get a reasonable (and traditional) gearing (so as not having to manipulate the levers too much back and forth)?
