Tripple to double Crank?
I'm intrested in changing my Tripple crank to a compact or even a regular double. My bike is five years old so I don't want to spend big $ on it. If I change to a double will I need a new shifter or a new FD(mine are both Tiagra). I think that the switch is doable if I just need a new BB and Crank. Also would this be a good time to change the chain and cassette.
Thanks.
