Front derailleurs have had a pretty stupendous run. Non-pin derailleurs have been around for decades, and perhaps the more spectacular thing about them is how little they've changed. They've been integral in the development of the bicycle, with technology and design always accounting for at least one of growing array of mounts that achieved the same purpose; move a chain from one ring to the other.
Some of the greatest images of cycling have interesting notes of the device, with riders in the high Alps looking down before a shift, or looking under theirs arms to make sure the chain line was perfect. A bit of clunking and chatter, perhaps a misshift, and then ping, it finally falls into place.
Especially off road, the front derailleur has served as the component brands have tried to engineer around for years. Smaller cassettes in the back, bigger rings in the front, and the slow evolution in the reverse of that theory have been done in no small part to reduce the amount of work and change the front derailleur is responsible for. SRAM and Shimano have slowly shrunk the front chain ring, narrowing the gap between the rings until the gain ration was so small, it hardly mattered.
1x drive trains in TC are perfect. They cover the same range as most 2x drivetrains and without the hassle of adjustment, or breaking chains, or dropping them. Want to see how your new setup compares to a 2x drivetrain, or want to see the difference between a 32t, 34t or 36t front chain ring? We use the Gear Calculator to compare ratios and top end speeds, sometimes down to the tenth of a mile per hour for the steep, low cadence climbs or where you'll spin out at, say, 108rpm on a 34x11 on 2.25" tires.
Ec is offering GX conversions for $550, which include a chainring, shifter, derailleur, cassette, chain and free hub. We also have X01 and XX1 options for $1000 and $1250. Or, you can mix and match between shifters, cassettes and other parts and dial it in exactly how you want it. It's a great time to check out a light crank as well, with SRAM and RaceFace in stock and ready to take some weight out of your race rig.
You know the benefits; better shifting, longer drivetrain life, no broken chains, and the same ratios as before. Think less, pedal more. As Forest Gump would say, "It's one less thing!"
