The thing is when I took the bike home I overlooked the condition of all the teeth on the chainwheels...the middle and smallest had some teeth "cut in half"...so I had the mechanic swap them out for me. W/ the initial 46-36-24 the granny gear was putting out a 1.5 gain ratio. Now with the replaced chainwheels as 46-39-30, the granny is putting out 1.9...this is with the 30T rear....it's a Shimano 7spd "G" cassette...If I do decide to keep this frame and rebuild it to my specs/usage...I may swap out the drivetrain, more specifically the RD, cassette and shift lever..
