The new 9point8 Stout stems are light, stiff, and offer a wider range of short sizes than most. They’re also offering more dropper seatpost offsets than anyone we’ve seen, including a reverse (forward) offset, for the new Fall Line R posts. But first, ever wonder where the name 9point8 came from? It’s the speed of gravity. Meaning, all else being equal, if you drop something, they say it’s going to fall at 9.8m/s. Kinda like you when you huck off that jump.

9point8 Stout stems are lightweight and super short for enduro mountain bikes

Their new Stout stems are made of 7075 alloy because it’s lighter and stronger than the 6061 normally used. They make them for 31.8 (30/40/50mm) and 35mm (32/40/50mm) handlebars. Note that 40mm length, it’s not a common size and a welcome addition for anyone trying to really dial in that fit. And the 32mm length for 35mm OD handlebars is because that’s the closest they could get without having to create an indented bar.

Retail is $99. Weights from 113g up to 138g with steel bolts. Or upgrade to Ti bolts for $19 more and save 14g per stem (as in, that’d put the 31.8×30 at just 99g).

The complete spacer kit (visible with all the parts in the top photo) is just $12, and the top cap with with star nut is $10 and is designed to wrap over the steerer with a little space so you don’t need another spacer above the stem.

9point8 Fall Line R finally shipping

9point8 Fall Line R dropper posts are finally shipping in April 2019

The top-of-the-line Fall Line R series was launched last year, but is now (finally) shipping worldwide. Retail is $399, plus whichever remote you want, and those range from $25-52.

  1. What!? “Speed of gravity”? Does the term “acceleration” and its unit of m/s² tell you anything? It is in the school physics textbook, look it up, please.

  2. “It’s the speed of gravity. Meaning, all else being equal, if you drop something, they say it’s going to fall at 9.8m/s.” Not quite, It’s the acceleration due to gravity. A falling object will increase in speed by 9.8m/s every second it is falling. Therefore it’s acceleration is 9.8m/s^2

  3. A couple of technical corrections – 9.8 m/s^2 is the acceleration of gravity, not the speed of gravity. Big difference. 7075 is not lighter than 6061 (the density is nearly the same), but it is stronger so a part with equal strength can be made lighter.

    The parts look nice though regardless! Thanks for continuing to post tidbits on new stuff, this continues to be one of my favorite daily reads.

  4. Facepalm. Read “the speed of gravity” and felt an immediate visceral reaction. Nice to see it was caught by everyone else too.
