Well it's about time! That's an awesome ride. The drivetrain looks totally tricked-out! I know that you've put a lot of planning and research into the bike for the longest time, and it shows. Well done!
If you think the bike is bone-jarring on 20x1.50 Comets, take that feeling and double it and you'll know what it's like to ride SF on the 20x1.35 version.
BTW: how are the brake levers working for you?
