News: SRAM Releases More Affordable 1×11 Drivetrain, the X1

SRAM radically altered the way that we thought about drivetrains with the release of their XX1 1×11 drivetrain in 2012, featuring a narrow wide single chain ring design, Type 2 rear derailleur, and astronomically-huge cassette range. While they did release an X01 version last year, that latest rendition didn’t truly do much to drop the price of 1×11 into the realm of the average mountain biker.

As a relatively-new 1×11 addict, thanks to the extreme simplicity and the fantastic chain retention, I’ve been waiting for the price on 1×11 to drop even more. With the release of X1, we continue to see the technology trickle down to more affordable levels.

Here are all the details from SRAM about their latest drivetrain, the X1:

Personally, I’m generally most concerned with the cost of drivetrain parts that you know will wear out with use: the cassette, the chain, and the chain rings. While I’m a bit disappointed to still see a rear cassette that costs north of $300, it’s still over $100 cheaper than the XX1 cassette. Chain cost has almost been halved from X01, and while no prices have been provided for the chain rings, it’s a safe bet that they’ve come down in cost as well.

Do note, though, that if you want to go grip shift, you’ll still have to shell out for at least X01-level shifters, but they should be compatible with X1 if you want to save money elsewhere in your drivetrain.

One thing is certain: when it comes time to replace some of my own drivetrain parts, I’ll be saving some cash with X1!
