Ergon GP4

The size refers to the grip circumference, not the length of the grip. The Small size is designed for smaller hands or riders who prefer a thinner grip, while the Large size provides a thicker diameter for those with larger hands or who prefer a fuller feel.

No, the Ergon GP4 grips are not compatible with carbon handlebars. The clamping mechanism is designed specifically for standard alloy or steel handlebars with a 22.2mm diameter.

Yes, the bar end is designed to be adjusted independently of the grip angle. This allows you to fine-tune the position for optimal leverage and comfort based on your specific riding posture.

Yes, the GP4s are anatomically shaped to increase the contact area between your palm and the grip. This design distributes pressure more evenly, which helps relieve stress on the carpal tunnel nerve and prevents the numbness often caused by standard round grips.

You will need a standard hex key (Allen wrench) to tighten the clamp. The bar end acts as the clamp, so once you slide the grip onto the handlebar, you simply tighten the bolt to lock it securely in place.

While they are excellent for touring and fitness riding, they are not intended for aggressive, technical mountain biking or downhill riding. The large bar ends can snag on trail obstacles, so they are best suited for gravel, trekking, and general fitness cycling.
