The N+1 has arrived! It's amazing!
11-34 rear cassette.
Shimano 105 shifters
Took it for a 22 mile test ride, it fits like a glove. The STI levers had a 5 minute learning curve; in less than a mile they seemed perfectly natural to me, despite having never used them before. Some wicked 30mph winds today, but amazingly I averaged 2mph faster than I normally do in these winds.
Since taking the pictures I've installed my Garmin GSC-10 and my Revelate Tangle Bag. Debating whether to install a rack on the bike at this point in time. Eventually I'll need one for long distance rides, and a front rack for touring, but those are probably next-year changes.
Additionally I'm still debating whether to go with fenders or not. They've proven to be amazing in the rain, and last time I cleaned my MTB's drivetrain pre-fender it was absolutely disgusting. I'll probably end up getting them to be honest. When I do it'll be SKS Longboards, probably silver, unless someone can convince me that black will look better.
