"Adjusting" Flat Bars - Flat handlebars may seem non-adjustable. But, if yours are too wide, they can be cut to customize fit and feel. Usually, riders who enjoy demanding, technical trails appreciate a little additional width (24 to 27 inches), especially when using dual-suspension frames. All-round riders prefer a more standard width of about 22 inches. If yours are too wide, it's easy enough to shorten them. Measure carefully to ensure you leave room for all the parts that fit on the handlebar ends (it's best to remove 1/2- to 3/4-inch sections and see how the bar feels). Riser bars are also available, which are models that slope upwards on the ends to provide less bend in your back when you lean forward to grab the grips. Many off-roaders find that riser bars are just the ticket for a more comfortable position.
