In collaboration with 77 Designz , We Are One Composites have manufactured one of the world's lightest and strongest bar and stem combos. The issue they tried to improve was the clamp force creating weak points at the bar to stem clamp interface. Testing and fatigue have shown that the interface between a regular stem and carbon bar can be hazardous. Irregular clamping force, low tolerance bar diameter, and harsh interactions between the bar and stem are the root cause of these issues. Their unique, yet simple design maximizes clamping surface area while spreading the clamping force through the whole area of the sleeve. With their patent pending location nipple on their carbon bar. With the carbon nipple, you can ensure alignment is perfect and capture the sleeve so it does not rotate. Da Bar has also been designed to a 33mm diameter in order to drop the stiffness and allow for the sleeve to slide into our 35mm clamp diameter of Da Stem. A new way of thinking about 35mm. Smart design meets absolute manufacturing excellence!

There’s something about 7/8" (aka 22.2mm) handlebars that seem to attract the most abusive riders out there, so we’ve taken our popular Boxcar stem and beefed it up even further! We already use 2024 alloy for all of our boxcar stems, as it has a higher fatigue and yield strength than 6061. We made sure the clamp was extra thick on this version and even added 2 more high-strength stainless faceplate screws. Is it overkill? Definitely. You’d have to run this thing over in a tank to damage it, but we’re pretty sure this will be the last 7/8" stem you’ll ever have to buy. - Machined in sunny Chico, California - 6 bolt faceplate (stainless T25 bolts) - 7/8" (22.2mm) bar clamp - Stack height: 36mm - 180g

Enduro has unquestionably evolved ever closer to Downhill. The Enduro MK3 Stem is all you need for hitting the trails with wingsuit type accuracy. This Stem was born out of rider's demands for precision and for those moments when you have to be inch-perfect. Taking design elements from our World Cup-winning Direct Mount MK3 Stem and splicing these with our critically acclaimed Enduro MK2 Stem. We developed the Stem specifically with Pro's and Bro's alike. It was obvious we all live for the same challenge of pushing our own limits. As riders, we want a Stem that inspires confidence to change lines through the middle of a rock garden like it's no big deal or slap the inside of a turn and translate all your weight to front-wheel traction. Providing ear-to-ear grins and saying to your mates at the bottom of a trail, "Did you see that?". From the start of the design process, it became clear that we wanted extra rigidity. To yield this, we would need to make the Stem using a forging process - a new thing for us. The result of this allowed us to achieve a more intricate shape than machining alone. It involves applying a huge amount of force to redirect the grain flow of the material. As a result, this gives superior strength, fatigue and impact resistance. Another area where we made a significant improvement in rigidity was by increasing the clamping surface area on the steerer tube. We've vastly increased this to give a stout, rock-solid feel and as close to the MK3 Direct Mount Stem as we could. Furthermore, everything is held securely by stainless steel bolts to ensure there is no rust even in the grimmest weather. In addition and like every Burgtec product, it's fully CNC machined and anodized in all your favourite flavours. Tested with the world's fastest jibbers and sendiest racers, this stem has everything you need to hit all those rowdy racing lines or pull that little bit harder off that big sender. - Forged and Fully CNC machined from AL6061 – T6 Aluminium - Stainless Steel Hardware - Available lengths - 35mm, 42.5mm and 50mm - Available in both 31.8mm (Black only) and 35mm Clamp - Weight: 35mm 138g, 42.5mm 152g, 50mm 160g
