The Ergon GP4 is based on the popular GP1 ergonomic grip with a large 130mm bar end for additional hand positions. The Ergon GP4 grip platform and bar end can be adjusted independently of each other so that you can dial in the fit based on your needs. If you are planning on using the Ergon GP4 grips on a carbon bar it is best to check with the bar manufacturer to see if they will handle the added leverage and stress that the 130mm bar end can cause.
