We can remember a time when running a carbon mountainhandlebar was a risky proposition, but thanks to companies like ENVE Compositesand its world-class carbon construction techniques, we don't even give it asecond thought anymore. The firm has recently updated its mountain barofferings and gave it a naming structure that coincides with its wheel modelsso you know exactly the type of bike and kind of riding the bars are designedfor. As you can probably guess, the M9 Handlebar is its latest downhilloffering providing a lightweight design with tuned flex helping the world'sfastest athletes stay in control on the most demanding tracks. The M9 is the widest bar in ENVE's lineup and comes in tworises, 30 and 50mm, so you can dial in the perfect bar height for your terrainand riding style. All ENVE mountain bars are constructed from a careful layupof carbon fibers, laminates, and resins that give them its strength and thedesired ride quality. You might have noticed that ENVE stayed with a 31. 8mmclamp with the M9 whereas the M7 jumped up to 35mm. The short answer is thatENVE was able to achieve the safety and strength numbers it needed with the31. 8 clamp and it better provided the flex profile it was after for DH use. Soimportant is this ride feel that ENVE recommends not cutting this bar less than780mm wide so it retains the desired characteristics. As with all ENVE product,there's no weight restriction placed on these bars and ENVE backs it up with a5 year warranty. Ride with more comfort and control with the M9 bars. Both rise versions of the M9's come in 810mm width and with8-degrees of backsweep and 4-degrees of upsweep.
