Hello,

I need to get a double FD, double crankset, and a left double shifter (all shimano).

I would like to get second-hand parts, and this will most likely end up mixing groupsets.

Would any double shifter work with any double FD (all shimano) ? I'm looking for internal cable housing so it wouldn't be a super old shifter.

Any 10 speed 50/34 crankset will do the job ?

Thanks
