The correct bars need the correct grips. Ergon's GC1, the grip for swept-back bars, is now available as in a BioKork version. The grip body is made up of 40% cork, certified sustainably grown in Portugal. All components of the grip are then made with ecology in mind. The central core uses 40% less plastics, replacing them with natural fibers. The clamp is pure aluminium and can be 100% recycled. The grip is a product of Ergon's GreenLab initiative.
