Position of brake levers can be tricky. "Stock" is so that bottom "point" of lever rests on flat surface, at same level as bottom flatted out part of the drops. Putting them too high or too low always looks amateurish.
Also be aware of compatibility of
1) wheel size - 27" vs. 700C
2) Brake caliper drop/clearance
3) Rear axle length
4) BB thread
5) Headset standards - there are different thickness crown races.
Actually a lot of things to be aware of that don't crop up with MTBs.
