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!

Availability: June 2014.

    Greg, I think you are right on in your assessment. My biggest issue is with the cost of the consumables. With that said, I am in the same boat that you are. I have had my current drivetrain for 2 years and it is starting to look pretty beat up. I think I will save a little more so that when I go to replace it I can get the X1.

    If I am not mistaken, to cut costs one could just by the shifter, cassette, chain, and derailleur and then purchase an aftermarket NW chainring to use with an existing crank. I don’t think there would be any alignment issues, however a Sram 1X expert may prove me wrong.

      As far as I’m aware, you are correct… at least, as long as you have a single ring crank. However, it seems like the X1 1000 crank is pretty affordable, especially when you compare it to the cost of the cassette!

    $300+ for a cassette?! The one thing I think is missing here is the rear hub. Doesn’t the cassette require a different freehub? Even if you didn’t need a different freehub, looking at over $1100 to upgrade. Ouch!
