Stems

Strong, light and elegant. Chromag's longest running stem, the Ranger, has a refined body shape that represents their own advancement in 3D modelling and CNC profiling. The Ranger is stronger and stiffer for today’s increased demands with blended body features to increase performance with a more fluid look. The Ranger evolves with the same physical fundamentals, more flow, and increased strength. Starting at 140g, the Ranger is light yet extremely stiff for positive control at the front end.

Zipp's Service Course SL Stem, crafted from 7075 aluminum, features a shape that's strong and lightweight, resulting in a best-in-class 1.85 grams per newton meter of stiffness. That results in no-flex sprints and accelerations. This stem is a favorite of Zipp ambassadors and pro athletes. - Distinctive Zipp cosmetics - Zipp Quickview integrated computer mount available separately - Lifetime warranty

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

The IN-Route High Rise Stem was designed to achieve a rider’s ideal position without the need of excessive spacers. This stem can provide 43.5 – 49mm of stack and does so by increasing the stack height of the stem’s steerer clamp and a positive stem angle.
