If you have been in the shop lately and happened to hear or been a part of a discussion with me on SRAM’s revolutionary idea of a single chain ring drive train, you likely got more than an earful. It’s exciting, simple, and very cost effective and I tend to get really worked up about the benefits and features that a lack of front derailleur has. I am admittedly a SRAM guy, and preface my passionate discussion of all things SRAM by making that clear before going off the rails about how much I love the 1X (pronounced “One-By”) system. That being said, the idea of ditching your front derailleur is brilliant for just about everyone. No really, unless you’re a hardcore bike racer, it’s a darn near perfect system and it has an amazing amount of upside to it. The 1X arrangement has been a mainstay in the mountain bike world for several years now and has revolutionized mountain bike drive systems. It’s a very hot topic right now in the cycling world, and more cyclists, triathletes, and occasional riders are making the switch. Should you make the switch? Read on and lets discuss the idea from a practical, mathematical, and cost standpoint.
