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

Burgtec's first range of signature handlebars developed with, yes you've guessed it! Josh Bryceland. Josh loved the sweep and rise of the Ride Wide Bars but asked us to make him something a bit higher. The Rat isn't one of those guys that's 'crazy' on setup, but he knows what he wants. - 38MM RISE: Back in 2018 Josh's idea was for something more versatile that he could use on all his bikes. After testing various prototypes, he finally narrowed it down to a 38mm rise bar, the perfect sweet spot. The first material thought was Carbon but after getting to ride various Alloy prototypes he just got more comfortable on Alloy. So, the 38mm "Ride High" was born. The same unsurpassed comfort and durability as all of the Ride Wide range, but just a little Higher. - 50MM RISE: It's fair to say high rise bars have taken a back seat over the last decade much in part to the increasing wheel sizes pushing up front ends of bikes and riders trying to match their previous riding positions. After first coming to us a little over 3 years ago and deciding on the 38mm rise bar Josh wanted to quite literally raise the bar once again. We'd previously prototyped the 50mm bar alongside the 38s but at the time just felt they looked out of place. With more riders moving towards 29ers we felt the market just wasn't ready for them. Josh quickly adapted to the 38s but still felt he was running a lot of stack on his bikes. So with more frequency, he was popping in to Burgtec HQ asking if we had any of the 50mm rise bars left. In the end, we ran out of prototype bars, and Rats a very persuasive guy so we just decided to go into production with the 50s. For Josh, he loves how the higher rise allows for more maneuverability as well as getting rid of the excess stack height. Plus, being a taller rider, they keep his weight where he wants it and freely admits "It's easier on my back". The bars are a natural fit for Jump bikes but as Josh and the boys show they are equally at home on bigger travel trail bikes too. - Width: 800mm - Rise: 38mm, 50mm - Available in 35mm clamp only. - Backsweep: 9° - Upsweep: 5° - Weight: 38mm Rise = 346g, 50mm Rise = 391g
