Ergonomics, functionality, haptics, and sustainability – the Ergon grip with the absolute best customer feedback! The grip body for the GP1 BioKork grip is made from 40% bio-cork. The material for the grip body comes from biologically certified cultivation in Portugal and meets strict ecological guidelines. All parts of the grip are consistently manufactured with ecological sustainability in mind. The BioKork grip is the result of the Ergon initiative "GreenLab." The GreenLab initiative places strong emphasis on Ergon's development with the goal of combining ergonomics, performance, and ecology in products. It was launched by Ergon in 2010 and has led to numerous product innovations, from biocompostable packaging to bio grip compounds and the use of plant-based leather from Allgäu organic cows. Intended use: MTB/Touring/Trekking.
