Upgrading to carbon fiber handlebars can help reduce fatigue in our hands and make for a more smooth and predictable ride. The PNW Components The Loam Carbon Handlebar is one of our favorite carbon handlebars for trail enduro or downhill riding. This bar comes in a 35mm diameter, has an 800mm width, and gives us the option of a 25mm or 38mm rise. PNW's wrist-saving geometry sports a 5-degree upsweep and a 10-degree backsweep to keep our wrists happy on long sustained descents.
