Introducing SRAM's XX1 Drivetrain: 1 Gear Up Front, 11 Out Back

View as: Slideshow | One Page
SRAM's new 1x11 drivetrain was officially released today. Highlights include the single-ring carbon crank, unique chain ring, horizontal parallelogram rear derailleur, and a super wide range 11-speed 10-42 tooth cassette. The increased range provides a much closer overall range to 2X setups than 1x9 or 1x10 speed offerings. Good riddance front derailleur. Can't say we'll miss ya. The complete system will retail for $1449.

    i want a one-by for xc so i like it. if it works like it sounds the standard freehub change over will be worth it. they use the word "perfect" enough i wouldn't expect a 12 speed in a year or two. but i've been in the bike world a long time, xx.2 in 24 months, but i hope not.

    i'm interested in this new derailleur design. i think that could really have some great potential, if it works as they say. but i think the 42-tooth cog is overkill for most trails.even in XC racing i can't see myself using a gear that low very often. i'd be more inclined to give this group a try if sram offered the cassette in a more reasonable range.

    With just one cog up front, the 42 in the rear becomes very usable. If you work out the numbers, it actually has a very similar range as present 2x10 drivetrains.

    i'm sure for some people it would be a welcome choice. i'm just disappointed that right now the new derailleur only has one cassette option. if chain retention is really as good as they say, i hope they make other cassette options available in the future, or maybe move that derailleur technology to a ten-speed option.

    Looks sick, just bummed about the new freehub standard.
