DESCRIPTION Particularly beautiful, an extraordinary strength to weight ratio are the key features of our Barkeeper stem. The cost extensive and highly precise production of this masterpiece includes many steps, including: - precise near net forging process - Multi-tempering - CNC machining of critical contact interfaces - Shot peening for surface hardening - Laser engraving - Anodizing All three available lengths (35mm, 45mm, 55mm) were successfuly tested to match and exceed the requirements for the strongest/highest possible category for mountainbike components (category 5) of DIN EN 17406:2021 and ASTM F2043-13. These tests were run with an 800mm handlebar width, which leaves plenty reserves for their intended use on "Trail" and "Enduro" bikes. The incredible attention to detail in manufacturing and finish quality can als be seen in areas, which are not even visible, when installed IMPORTAN NOTE: The obvious one-piece design allows for an incredible high strength-to-weight ration, but it does cost some compatibility. Not every handlebar will be compatible to our Barkeeper stem. Although we have successfully tested handlebars with 35mm rise, there is no guarantee for compatibility. We assume most handlebar with a rise of up to 30mm will work, but it greatly depends on the slope and shape. You can find a list of compatible handlebars next to this description under "compatible handlebars". We will try to update this list, so feel free to let us know, once you have successfully installed a handlebar, which we can add. This list makes no claim to completeness or correctness and is only to be understood as a reference.  SPECS: Rise: 0° Stack height: 40mm Clamping width: 50mm Compatible steerer tubes: 1 1/8" Compatible handlebar diameter: 35mm clamping  for handlebars up to 800mm width Material: Aluminum Al-7075, multi-tepered WEIGHTS (titanium / steel bolts): 35mm length:   80g   /   86g 45mm length:   90g   /   96g 55mm length: 106g   /  112g COMPATIBLE HANDLEBAR: 77Designz Carbon 35, 800mm x 20mm Rise, 5° Up, 9° Back** Hope Carbon Handlebar, 800mm x 20mm Rise* OneUp Components Carbon Riser, 800mm x 20mm Rise* OneUp Components Carbon Riser, 800mm x 35mm Rise* Race Face SixC 35 handlebar 820mm x 20mm Rise (allowed up to 800mm)* Race Face SixC 35 handlebar 820mm x 35mm Rise (allowed up to 800mm)* Race Face Turbine R Carbon 35, 780mm x 20mm Rise, 5° Up, 8° Back** Spank Spike Vibrocore 35, 820mm x 25mm Rise, 5° Up, 8° Back (Approved until 800mm)* * tested and verified by BikeYoke ** consumer feedback, not verified Please visit our website at http://www.ecomtb.com.my OR https://shopee.com.my/eco_mtb ** There is 1-3cm errors due to manual measurement.
