Frankly, when we built this bike and the SRAM mechanic told me that I would be just fine with one chain ring (54) on the front for a course like Ironman Lanzarote I wasn’t sure if he knew what he was talking about or if he just hit too many granite walls freeriding but there I stood with the SRAM Force 1x ready to try out what everybody seems to love on the MTB but oddly enough doubt on the road or tt bike.
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.
