When you're spending hours at a time on the bike, exploring the roads less traveled or reveling in your favorite bit of singletrack, you need a shoe that guarantees all-day comfort without weighing you down. Something that's breathable regardless of the conditions, with rugged construction that can withstand the rough and tumble of any trail. The Sector is one such shoe, built with a stiff and lightweight carbon composite sole that transfers all of your power to the pedals, and Giro's proprietary Synchwire uppers for the ultimate combination of lightweight breathability and outstanding durability.
