SRAM 1×11 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 1×11, 2×11 or 2×10 for a massive range of gearing. And it is available at a price of $564 for the 1×11 configuration. That is 47% cheaper the the SRAM X1‘s price of $1066

1×11 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.

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.
