Bolt up, and hang on.

You gotta love that the Easton Havoc Stemis CNC machined from a solid block of aluminum. That's gonna give you some serious steering confidence. But sheer mass alone isn't the Easton modus operandi. They've also built in a bit of science -- even if that's the farthest thing from your mind as you gap a rock garden and dive for the next wall ride.

Eye up the Havoc Stem nose-first, from the face plate back toward the steerer, and you can see their first trick. The face clamp has scalloped shoulders that crest in toward the bar contact patch. This broadens the clamping force, and the same shaping is also used at the mouth of the stem itself. This ensures that the stem doesn't create a stress riser at the bar/stem junction, and the massive bending loads that the bar experiences when you land a jump get distributed along a greater portion of the bar. This design helps the Havoc Stem make your bars more durable.

And even if you're mostly wanting a stem that's totally bombproof, Easton still milled out the body of this stem to remove all extraneous material, reducing weight and consequent steering heft. Note how even the steerer clamp is pared to a minimum. There's simply no need for extra alloy here, as the stress on this part of the stem isn't as great as it is at the bars -- where Easton wisely concentrates the bulk of the Havoc Stem's mass.

The Easton Havoc Stem is made of Easton CNC Aluminum, and is available for 1-1/8" steerers. It comes in 35, 50, and 65mm lengths. It fits 31.8mm handlebars and has a 0° rise. Color options include Gloss Black and Orange anodized.

  • Familiarity: I've used it several times

Not much to say about a stem, but the Havoc is great. I picked up the 35mm length to run on my SC Nomad when I'm riding bike parks and DH trails. I definitely prefer it over the 50mm when the bike is pointed downhill.

Sweet Stem

  • Familiarity: I've put it through the wringer

I've been running this stem for about 3 years. While it may not be the lightest option it looks great and is super durable. Excellent option for a trail or freeride bike.

Stable, Sturdy, Studly

  • Familiarity: I've used it several times

This stems has the trifecta of being reliable and cool looking. Matched it up with a Black/Grey Trek Fuel Ex 8. Looks sweet!

Super Strong

  • Familiarity: I've put it through the wringer

This stem is made burly! Easton did a bangup job machining and cutting away any excess material that isn't needed for utter strength. The clamping surface is a bit wider than some other stems to work better with wider bars. Also, their TopLock design makes for a super simple install, especially when using carbon bars.

Super Duper Stem

    This stem is great when it comes to AM/Freeride/Gravity set ups. It gets the job done and matches up pretty sweet with the Havoc or Haven bars. I'm a fan and would recommend it.

    Super Duper Stem

    Schweet Stem

    • Familiarity: I've put it through the wringer

    This stem is SOLID. i like the top lock design. you shouldn't have any issues with sliping if you follow the torque specs. the orange adds some nice bling to your ride too.

    It'd be great if they could get the weight down without losing stiffness. Orange carbon fiber?

    where can i get a spacer for the 1 1/2 version

    Burly and shiny

      Suh-weet. I need to shorten the OEM stem on my Slayer and this did the trick. It was the right length and it is far beefier than anything I'll ever throw at it.

      The Top Lock feature is a nice touch to visually check for tightness around the bars. I've had previous stems come loose on climbs and once on a descent. Not cool. So this is a great thing to have.

      The machines surface and finish is uber cool and it keeps it from being super bulky. Plus, it adds just enough bling to the bike. I like!
