Bikes: 2014 BMC Gran Fondo, 2013 Brompton S6L-X

My first B - a 2012 S6L, came with a 50T chainwheel/crank. I swapped that for a factory 44T: https://www.youtube.com/watch?v=hYo8Ta8SBxE&index=21...

My 2nd B - a 2013 S6L-X, already came with a reduced geared 44T chain ring/wheel. I swapped that for a 39T Dura Ace ring. By the 12:50 mark of my video is a steep hill where a lady(a lot of guys also by the way) is pushing her bike up. Meanwhile; my B'ton is cruising along nicely https://www.youtube.com/watch?v=5AT6wI_J2MI...
