Norco Optic A Frameset Ready To Tear Up The Trails Trail bikes are great at many things. From tearing up long climbs to tackling challenging descents, these bikes are highly capable and ready for your next adventure. The Norco Optic A Frameset condenses years of technology from long travel bikes into a lightweight package that's as ready to rip it up on the trails. The aluminum frame uses a VPS suspension layout that provides an increased rearward axle path and an idler to manage pedal feedback. With 140mm of travel on the front and 125mm of travel on the rear, you'll have no problem conquering aggressive singletrack and steep climbs. The frame also features co-molded frame protection, internal cable routing, clearance for up to 2. 6" tires, an integrated accessory mount, and long travel dropper post compatibility, and it can be converted from a 29" to 27. 5" rear wheel with a Missing Link Kit.
