bar ends are extensions at the ends of the bicycle handlebars. Usually fitted onto mountain bikes with straight handlebars, they extend away from the handlebars and allow the rider to vary the type of grip and posture that they use during a ride. They are especially effective when climbing out of the saddle, because they increase leverage. Bar ends can also improve comfort for the rider due to the neutral position of the hands (palms inward) which places marginally less stress upon the musculature, and by providing more than one place to rest hands on a long journey.
