The Enve M5 MTB 31.8mm Handlebar is a fly-weight, modern flat bar for XC and trail riding, available with a +/- 5mm rise. There will always be a demand for the original MTB bar. Lighter and lower than other styles, the flat bar is still the first choice for many XC and trail riders. ENVE updated this bar to fit even more riders with an increased width, and positive or negative mounting positions. The Enve M5 MTB 31.8mm Handlebar is ENVE's lightest XC and trail bar. Designed with an offset grip position and 31.8mm clamping surface, the bar can be mounted with a positive or negative rise of 5mm. This incredibly versatile bar combines a familiar 9° sweep with the greater width and strength that’s demanded by today’s more aggressive XC riders. Enve M5 MTB 31.8mm Handlebar Features Width and Stiffness  Each ENVE bar is available in a specific width with cut lines to size the bar more appropriately for the rider. Often ENVE are asked, “Why aren’t all ENVE bars made extra wide?” It’s a good question. Each bar must pass their testing to earn its rating, requiring the wider bars to be stronger. However, if everyone is cutting those bars, the bar then becomes overbuilt and too many riders are forced to modify and resize. A subtler but equally important reason for not making each bar as wide as possible is that the width of a bar is a key element of its flex profile and feel. Like any handlebar, if the width of an ENVE bar is reduced, the stiffness increases, so ENVE build each bar in a specific length for the optimal weight and ride quality. For the M Series bars, we have actually reduced the recommended cut lengths in order to guide more riders to the correct bar. Rise The M Series handlebar line includes additional low and high-rise versions in key models to ensure that you can achieve a perfect riding position. As well as adjusting the height of your cockpit, the compound angles used to create the rise also provide a wider range of hand positions as you roll the bar forward or back in the stem. This is why you will see minimum rise 7.5 and 10mm options available for riders who need a low position, but demand the adjustability of a riser. Clamp Diameter ENVE now offers bars in the two most popular stem clamp diameters; 31.8 and 35.0mm. When choosing your next bar, consider these points. ENVE's Trail category M5 and M6 bars are all 31.8mm. This size allows them to achieve the optimum, compliant-yet-responsive flex profile for trail use while also minimizing weight. The M9 Gravity bars are also 31.8mm. Professional DH riders love them and still prefer their feel when combined with stiffer double crown forks on rougher tracks. The M7 bar features a 35mm clamp diameter for riders who want a stiffer feel for ultimate precision when attacking big terrain on long-travel bikes. The M7 also has an ‘oversize’ aesthetic which some riders find well-suited to a gravity bike.
