From Jun2017 to mid-March of this year, I did the weekly distance you're talking about on the bike shown. Now I'm working from home. The Rohloff has been excellent, very low maintenance, I use Connex 8SX chain and get lots of miles before needing replacement. The shop that set this bike up did a stellar job on bike fit, and this is one comfy bike. I got rid of the Thudbuster seatpost and put on a Thomson Masterpiece, quit using the panniers and went to a big seat bag from Rivendell. It holds my laptop and lunch well. I also run with fenders when commuting, of course.
