Gear Levers and Shifters
The gear shifters on your handlebars usually incorporate both the brake and gear levers in one, and are shaped for comfort and ease of use. Each brand uses their own designed system, so it is important that you match this with the rest of your drivetrain, however you may be able to upgrade your ‘shifters’ to bring down the weight and improve the shifting performance. TT shifters which fit on the end of time trial handlebars are also available as well as standard road bike shifters. Mountain bike gear shifters are designed specifically for use on flat handlebars.
