I ride a 2×11 and was convinced that I would upgrade to a 1x asap, but I’m actually loving the 2x and using both rings a lot. I think you have to really have a hard think about the trails you are and will be riding and the types of climbs you are going to do and also your fitness levels before changing to a 1x. If you do decide to go 1x make sure you are doing for the right reasons not marketing hype – are you doing it just for simplicity and/or are you actually trying to save weight. And if you are saving weight what other parts of the bike can you save weight on too to make a significant difference.
