1st commute in 2 wks and I only forgot my helmet, and to turn off the gps app on my phone when I got into the office.

Also 1st commute w/ new 1x9 setup on former fixie. I can really see the logic of 2x9 because right now both ends are cross-chained. On the other hand, w/o a 2nd chain ring, while there is cross-chaining, there is nothing to rub on so there is no annoying buzz.
