Changing gearing on old bike
So I promised a older friend I would try to help him out in order to get him back on his bike. He is complaining his gearing isnt wimpy enough for him. Its a trek from the 70's, so is got friction shifters and mostly some sort of suntour components, and is a 12 speed.
His current cassette is a 12-23, and 52/42 chainrings (I didnt double count... it may be 53/41 or something... and didnt see anything stamped)
There is a used bike parts store nearby. I was considering getting him a new cassette/freewheel group with a bigger cog, as well as some different chainrings (Id rather not try to swap cranksets/BBs)
I have no clue what that rear derailleur is, but as long as I keep the difference at 10 teeth (like a 49/39) would I be in the clear? Also, as long as I keep the cassette/freewheel difference from small to large, will that work out as well?
Obviously I may have to shorten the chain depending on all this...
