ENVE's obsession.

It's trivia time at Competitive Cyclist. Q: What product have the meticulous engineers at ENVE obsessed over more than any other in their impressive product line? A: The Mountain Stem. It turns out that they've developed and discarded more prototypes of the new Mountain Stem than any other product that they manufacture. We were shocked to learn that, too, since they've already produced a stem that works just fine on mountain bikes. We were even more shocked when we saw it, since ENVE managed to one-up its previous stem design in looks. But ultimately, a stem isn't about looks, but quality, so we ask again: What was ENVE thinking?

It turns out that ENVE just wasn't satisfied with the previous stem's weight. It wanted to push it even lower, getting below 100 grams. The only length to fall outside of this mark is the longest, 85 millimeters, which weighs a claimed 104 grams. The other stems range from 85 to 99 grams, giving the whole series the best strength-to-weight ratio of any comparable mountain stems on the market today. The unidirectional carbon fiber's threads are molded in, and titanium hardware connects it to the aluminum face plate. This construction makes the stem light, as noted above, and it also makes it durable enough to ride fearlessly on cross-country, trail, and enduro events.

  • Ultra-light and strong carbon fiber stem
  • Aluminum faceplate and titanium hardware
  • Lengths from 40mm to 85mm
  • Designed for mountain use.

Fantastic Stem

  • Familiarity: I've used it several times

Typically a stem is not likely something would say much about, but this stem is great. It is high quality, extremely light, and looks great. It is properly rigid on the gravel bike and provides good feedback without being overly complicated. Very happy with the purchase.

Great quality and as light as it can get

    I thought the box was empty, but it actually contained the ENVE stem. It's so light you own't even notice it.
    Performance wise, it's everything you can expect from ENVE.

    Doesn't Work With Enve Garmin Mount

      The face plate on this stem is larger than the regular Enve stem. As a result, the Enve Garmin mount (sold separately) is not compatible.

      So Clean and Light

      • Familiarity: I've put it through the wringer

      I am really impressed by how much I like this stem. It's so light and so clean. A huge improvement from my stock stem and has paired amazing with my Enve bar.

      Enve Quality

      • Familiarity: I gave it as a gift but have feedback to share

      I gave this as a gift. This is what was said
      "Nothing but high quality from Enve. At nearly half the weight of the setm I replaced, this is a great, sleek way to shed a little weight. It;s the perfect complement to an Enve handlebar as they feel like they become one. Great control and a natural feel. it also look fantastic. If you can stomach the price, this thing will not disappoint. "

      Just a very nice piece.

      • Familiarity: I've used it several times

      The quality of this stem is impeccable. All the surfaces are machined very well and the weight is minimal. A very nice addition to any great mountain bike.

      Unanswered Question

      Anybody have a recommendation for enve stem length (70 vs 85mm) for a santa cruz tallboy LTc large? I'm 6'1, 34" inseam and ride all mountain (basically 50% climbing and 50% descending). I currently ride a santa cruz superlight large with an 80 mm stem and it feels pretty balanced.

      Which ENVE stem would you recommend for a Salsa Beargrease?

      This all depends on your preferred reach. What length are you currently running? If you want to sit a tad more upright, get something shorter.

      What would you recommend for the Santa Cruz 5010 medium sized frame? I am already using the Enve RSR bar. Also, can anyone explain the need to rise the 6 degree?

      Best Answer

      From my guess 6 degrees is often the safe angle often relative to head tube angles on dual suspension rigs these days. Running a 0 degree stem is not as popular now compared back then. My Titanium Merlin runs a 0 degree and a 100 mm Thomson elite stem. But then again its a Hard tail so my riding position is pretty much hunched over..which helps when climbing but a pain when riding all day so comfort is critical as well to compliment and get the most out of your rig. With Dual suspension rigs, angles are a bit more aggressive for trail management at high speed..if i dare say. So with that, Stem and Steer angles would set the rider at a more balanced position along with the proper frame sizing and saddle position as well. So once you get it, you can always flip the stem and go negative 6 along with a couple of spacers taken off to get a more lower body position over your bike. But hey that's just my experience. Either way experiment and find your comfort zone. Everyones different in the end.

      • Familiarity: I've used it several times

      If the mountain stem were a potential dating partner and this was a dating ad, I'd say something along the lines of 'soulmate' and 'relationship unicorn'. This isn't a dating ad, but I'm still claiming both. Between the clean lines, the simple aesthetic (because physical attraction is important), the strength, weight, the quality (we're looking for a partner here), and the warranty (which you'll never get with another human), ENVE has another winner. And no, not just because I'm a notorious fan girl.

      I like quality. I like good looks. But ultimately? I need strength. I need a stem that won't back away from a nasty climb or a technical descent, and I need it to be lightweight for a trail bike. ENVE's mountain stem was my answer, and it was the best one the industry has come up with so far. With unidirectional threads molded into the seamless carbon construction, ENVE has all but guaranteed the strength AND lightness of this stem, especially when mated to an aluminum face plate with the titanium hardware. But the description already says that.

      Initial feel test:

      "Holy moly, this is light." Installed it.

      "Uh oh, is it too light?!" Rode it.


      Paired with ENVE's DH bar, the mountain stem dampens, responds and handles better than cockpit combo I've ever run. Ever. That's kind of a big deal. But the kicker: Is it worth the cost? Absolutely. Overhyped? Only if you haven't ridden it.

      Give me a call at 801-736-6396 ext 4768 or shoot me an email at and we'll talk about stem options and sizing.

      Sounds like love at first sight. I'm sold, however, I'm gonna have to wait 2 weeks, because it's backordered.

      You find a partner yet? It’s a good stem, but yeah... it’s a stem ;)
