I have not thought this through
My commuter's an ancient mountain bike, it's got 7-speed mtb shifters of some sort- altus I think. But it's undergeared so I'm throwing a road crankset onto it. It'll fit, but, the odds of my 90s exage mtb front mech playing well with a road double seem... slim.
So, any advice? I can see it working with a road front mech since all the control will be done by the end stops. But it might make sense to replace the shifter. (as long as it's cheap!).
Single ring obviously works and I think I'll start there but it'd be nice to have some shifting.
