So I have an opportunity to acquire a Brompton.. only thing is it has the M style bars.
I really want S style. If I put a mid rise bar like the Joseph Kousac one will that screw my geometry or is this a good solution without investing in a new stem.. Any opinions / experience / Tips ?? Oh it's a 2016 model.. ( I am not worried about adjusting cable lengths I have a fully equipped work bench..)

Thanks gang..
