Remember our TT-Bike bike built earlier in the season. ( http://talktotill.com/project-dream-bike/)  The goal was to build a super efficient racing machine based on the SRAM 1x. A groupset I had never ridden before. Since building the bike I raced races like 70.3 Aix en Provence and Ironman Lanzarote on that bike and fell in love with the 1x so much that we now decided to rebuild the touring bike with a 1x as well.
