Machined Beauty

  • Familiarity: I've put it through the wringer

Stems don't get much attention....until now. The stem is a critical component that often gets overlooked but not when you're rocking the Deity Copperhead. Aside from being absolutely gorgeous and a machining marvel, it performs just as well as a looks. Lightweight, super stiff, and a clamping design that holds carbon bars without friction paste and a super low torque on the faceplate bolts. The death of a carbon bar is over torqued bolts and not a worry with this stem, it's designed so well you don't need to get crazy tightening. I have the 50mm orange (talk about flashy!) that I love so much, I installed the 35mm platinum on my other bike.

    USA made, Idaho grown stem, fantastic option for those of you looking for a little upgrade on the stem front. Great aesthetics and craftsmanship!

    Great Stem, Great Color

    It's tough to beat Deity hard parts when it comes to fit and finish. Their new stem is no different! I paired this 35mm stem with their Skyline 787 bar and haven't had a problem so far. They feel stiff and solid and the anodized orange is bright and looks like it will be very durable

    Deity makes some of the best mountain bike accessories on the market in my opinion. This stem is one of the beefiest and best looking on the market. Mine is 35 mm And provides my extra large bike with the perfect reach. I would most definitely recommend this product and many other products from deity.

    Looks good

    Needed a slightly shorter stem for my trail bike, and this thing looks great! Not the lightest stem on the market, but great for the price. Highly recommend Deity to all my friends!

    Great Cockpit

    • Familiarity: I've put it through the wringer

    I've used Deity in the past for on dirt jumping bikes but never for trail/enduro. I have heard a lot of good things so I decided to give it a go on my new rig and have to say this is by far the best cockpit I have ever had. I paired the 35mm Copperhead stem with the Blacklabel 800 25mm riser bars. After a few rides I trimmed the bars down to 780 (800 was just a touch wide for my taste), now everything feels completely dialed. It puts me the perfect position for all types of riding and it allows for a great feel for the bike and terrain. Highly recommend this bar and stem combo.

    Great Cockpit

    Gorgeous stem!

    I Have always been a huge fan of Deity components, and this stem is another notch in deity's belt of winning product. It is light weight, stiff, and well cut, plus the color selection to choose from is great. The design put in to this stem is excellent. I would recommend this to everyone looking for a new stem, One thing I found is you may need to cut your steerer tube down. I had a race face turbine stem before, and had to cut around 1/2 inch off my steerer tube, as this stem has a shorter stack height.
