On today's road bikes, silver stands out amid the sea of stealthy black color schemes. This time-honored color is available on the Zipp Service Course stem. Since the introduction of our line of Service Course and Service Course SL components, we've had amazing success with our pro-level athletes in all disciplines. While the successes have reinforced our design decisions, we have also drawn from their feedback. We not only learned how and why athletes make their equipment choices, but how our manufacturing methods and materials affect product performance. With new knowledge as well as new engineering methods, we are proud to introduce our completely redesigned line of Service Course and Service Course SL stems. - Class-leading stiffness-to-weight ratio - More options for a better fit - New faceplate and geometry for greater stiffness and easier installation - Distinctive silver finish

All Box stems are engineered and crafted using our Oversized Technology. As we follow the load paths down the handlebars we have focused our attention on the stem-to-bar interface. Since the Oversized handlebars have an increased wall thickness and tube diameter in this sector we have reciprocated with an augmented stem interface with greater surface area. We’ve done this by moving material from low stress areas. This has greatly minimized twist and contributed to responsiveness. As the stem in mated with the handlebars we have contributed to increased pedaling stiffness by providing a backstop to the “lifting” phenomenon. There is no point pushing hard on your pedals if you can’t pull up on your handlebars and deliver that power. Power can easily be lost to handlebar-to-stem deflection and the consequences can be poor power delivery and steering control. When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency. Key differences: In this particular model stem we’ve modulated the Oversized formula to emphasize pedaling stiffness. We have transferred material specifically to sectors that experience sudden stress from pulling up on the handlebars. You’ll feel a difference in your acceleration. These stems are engineered for the larger-sized racers. -Material: 6061-T6 Aluminum -Process: Cold-Forged -Hardware: Chromoly Clamping Bolts -Finish: Anodized w/Laser-Etched Graphics Weight: -48mm: 280 g / 9.8 oz -53mm: 290 g / 10.2 oz

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
