No crack stem here.

Here's a bit of all-mountain bike bling that's hard to ignore. The Easton Haven Stem has the highest stiffness-to-weight ratio of any stem Easton's ever produced. That's saying a lot for a label as legendary as Easton.

They achieved this by CNC machining away a huge amount extraneous alloy at the steer tube end of the stem, leaving behind a steerer clamp that's just as sculptural as it is structural. The machine work at the handlebar clamp is what Easton calls Top Lock, where it's designed to be assembled in a certain way. The uppermost portion of the clamp should be tightened first, actually "locking" the top portion together. Then you'd proceed to torque the lower two bolts to spec. This perfect match of the faceplate against the stem body better distributes clamping force, and reduces any excess load on your bars due to uneven clamping pressures which can cause damaging fatigue.

Without getting lost in all this talk of amazing strength, the Easton Haven Stem is ridiculously gorgeous. It may just be a stem, but you can tell Easton's engineers and graphics teams suffered to make this one shine.

The Easton Haven Stem is made of Easton CNC Aluminum. It's available in 55, 70, 85, and 100mm lengths with an oversize 31.8mm clamp diameter. It fits 1-1/8" steerers and has a 0° rise. Color options include Gloss Black and Magnesium.

Does the job great.

  • Familiarity: I've put it through the wringer

I have this in a 55mm, and I've moved it from bike to bike because it just works. It's not flashy, but it's also not heavy and it's made well, and I have had no issues with bolts rusting or creaking like I have seen from other brands.

What is the handlebar diameter for this stem?

Best Answer

Todd, this is a 31.6 diameter.

fully ridable

  • Familiarity: I've used it several times

riding XC may not require the most durable stem out there but I have no trouble trusting the Easton stem. It's well made, not super heavy, pretty inexpensive. I'd but it again.

Clean, Strong, Perfect?

  • Familiarity: I've put it through the wringer

Aside from having the length I need all I really look for in a stem are stiffness and, when achievable, looks. The Haven checks all the boxes. Super stiff, very clean looking, and certainly a competitive weight for you gram counters. I swapped from a 35mm Havoc to a 55mm Haven and didn't have any noticeable increase in flex. for anything short of DH/Freeride I would go with the Haven over the Havoc for the stem. I have the Havoc carbon bars and they are a great match for my AM bike.

Burly, probably more than you'd expect

    The main reason I bought this stem is because I wanted a good looking, shorter stem with a zero degree rise/drop to it. Having the Havoc stem from Easton, I was expecting the Haven to be a bit lighter and more XC style. While it's a bit heavier than I was expecting, this isn't some whimpy road stem. While it is a bit on the heavier side, this stem has everything else going for it: super strong, great aesthetics, and stupid simple installation.

    If you haven't used Easton's TopLock stems in the past, you are missing out. Simply tighten the top bolts all the way down, then torque the bottom 2 to spec. Not only does this make the top of the stem look really clean, it makes torquing pesky carbon handlebars a breeze.

    Gone are the days of waiting for the first carbon crack then backing off a quarter turn. Wait, don't EVER do that!

    Great stem

    • Familiarity: I've put it through the wringer

    This is an awesome stem-lightweight and stiff. Makes a nice complement to the Haven Carbon Bar.

    XC only/not for shredding

      Running the Havoc carbon bars full length with the shortest (55mm) haven stem on a Transition Covert. These components came stock on the bike. Bars are strong as an ox but the stem twisted and bent. Probably not the best option if you ride hard.

      Super stiff and strong

        Looks great. Very light and supper stiff. Does not flex at all. I am running the 85 with the haven carbon bars. Makes a nice setup. Super stiff.

        Built for Blasting

          Running this stem in a 55mm with 720mm bars on a '09 Heckler that I ride as my do-it-all, aggressive trail bike. Stem feels stiff, although not the lightest (but I wasn't really concerned with this).

          Swapped to this from my slammed Easton Havoc stem that felt a bit too cramped. Happy medium between control when you're blasting and having room to stretch out on the pedally bits.
