You won’t find better quality carbon handlebars at any price. All Wren Carbon MTB handlebars are hand laid using aircraft-grade, Japanese Toray carbon. Layups are AI designed to maximize strength while saving weight. Each individual handlebar is weighed and put through a rigorous quality control check to ensure consistency.   We offer some unique angles on the widest carbon mountain bike bars in the industry at 840mm!   Why Carbon? Sure, carbon can be lightweight but that's only a small added benefit of rocking carbon bars. Carbon fiber's vibration-damping characteristics are far superior to aluminum making it an ideal choice for handlebars. The longer your ride, the more your wrists, elbows, and shoulders will thank you.   Have cold fingers? Carbon is a temperature-neutral material, unlike aluminum. Metal bars are essentially heatsinks for your hands in the cold. Carbon bars can go a very long way in ensuring your fingers stay warm when cycling in the cold.   Wren No-Nonsense Carbon Handlebar Specifications Series Clamp Diameter Rise Up Sweep Back Sweep Width Weight 310 31.8mm 0mm 0° 6.5° 750mm 170g / 5.9oz 330 31.8mm 15mm 3° 5° 750mm 181g / 6.4oz 350 31.8mm 25mm 5° 9° 840mm 240g / 8.4oz 360 31.8mm 42mm 5° 9° 840mm 239g / 8.4oz 380 35mm 25mm 5° 9° 840mm 223g / 7.8oz   Wren Carbon MTB handlebars may be cut down to fit your specific width.
