Weight: 333g Carbon Fiber Lever, Aluminum Body Organic, Top Loading pad w/ Aluminum backing plate Contact Point Adjustment, Reach Adjustment, Adjustable Banjo, Tri-Align Calliper Positioning Taper Bore Technology Ambidextrous GLOSSARY: Taper Bore Technology The term Taper Bore refers to a unique patent-pending closure system. It saves weight, looks super-sleek, improves lever feedback & most importantlygives you more power & control. Contact Point Adjustment Allows you to customize the point in the levers throw where the brake actually engages. Contact Point Adjustment is not a reach adjuster (although all of Avids levers have that, too). Whether you prefer the modulation of a longer throw, the instantaneous power of a short throw, or any of the options in-between, this feature will help you dial in the perfect ride. Power Reserve Geometry Avid designed their levers with the pivot closer to the handlebar, in fact, closer than anyone else in the industry. The resulting lever movement has less inward travel, an arc thats closer to your fingers natural motion & delivers more force to the brake. Tri-Align Caliper Positioning System With Avids Tri-Align Caliper Positioning System, aligning the caliper to the rotor literally takes seconds. Just loosen the CPS bolts a little, & then squeeze the brake lever while re-tightening the bolts. Perfect caliper alignmentjust like that.
