SRAM 1x11 is one of the best innovations to come to mountain biking in the last decade. It has simplified riding as its expanded rear cassette range has allowed riders to just stay in one ring in the front.

It has changed the way we ride by allowing the mind to focus the right hand on shifting. It has also freed up some real estate on the lower left side of the handlebar for the now all-important dropper post lever. And it has simplified chain management and retention with the use of X-SYNC Narrow-Wide chainring technology that seems to magically mate the chain and chainring together.

But there's been two knocks on this line-up from SRAM: "The gearing is not low enough. And it's too expensive." These are the complaints most often heard about the three models available, the XX1, XO1 and X1.

This  chart compares the weights and price of the the 1x11 components.

SRAM GX is here to tackle both these issues head-on. SRAM GX is now available as 1x11, 2x11 or 2x10 for a massive range of gearing. And it is available at a price of $564 for the 1x11 configuration. That is 47% cheaper the the SRAM X1's price of $1066

1x11 is the crown-prince of this GX line-up as it is the configuration that everybody lusts for. In fact, some bikes now like the Santa Cruz Nomad and Specialized Enduro 29 don't even accept a front derailleur. The highlight of this 1x offering is the SRAM GX cassette shown below. In previous versions, the least expensive SRAM option was the X1 cassette at $313. Now, this new GX cassette costs $144 only and we expect shifting performance to match that of its predecessors. It weighs 394 grams which is 79 grams more than the X1. It is an absolutely fair trade as this is a wear item that has to be replaced periodically.

This chart shows what drivetrain people are currently using on their primary bike.

And of course this is cross-compatible with the XX, XO1 and X1 groups so one could even use the $144 GX cassette to replace the $432 XX1 cassette if weight is not too much of a concern.

SRAM GX 2x11 - Available August 2015

If 1x11 is the group most lust for, 2x11 is the answer to the call of many who long for a lower gear. There's a few out there (ahem, Europe) who seek a higher gear as well for the extended periods of fire road or pavement.

But one thing many don't realize is that 1x11 is a bit of a compromise. Often, low gear is compromised because the romance with simplicity and handlebar real estate is so rewarding. The front chainring on a 1x11 drivetrain is best when it is customized for one's power, weight, terrain and wheel size. Put it a formula and hopefully a 32, 34 or 36 number pops out as your ideal match. If not, you have to man up, get strong or get a 26 or 28 tooth front ring. Those work but they don't have a good high gear range and pedaling efficiency is compromised with such small rings.

So for those riders where 1x11 is a stretch, there is now a solution, 2x11. This 2x solution has the fabled 10x42 in the back so you can hang out in one chainring all day. But when you finally run out of gearing in the back cluster, you have more. Plus the front rings are not so far apart that front shifting is difficult under load or abrupt.

The downside of course is you have a front shifter and derailleur again and lose the magic of Narrow-Wide chain retention and management. But hey, now you have a choice during purchase and you're not locked in during the life of your bike.

SRAM GX 2x10 - Available June 2015

2x10 and it doesn't quite have the compelling proposition of its other two sibling as it's only $50 cheaper than 1x11 and its range is nowhere that of the 2x11. But it doesn't require the new XD cassette driver body so backward compatibility with existing wheels is its forte. And some might argue that 10-speed is more robust and more resistant to dirt and grime than 11-speed. Either way, GX is all about choice and options so SRAM offered 10-speed compatibility in the GX line.
