Using these Ergon GD1 grips is easy. Just install them on your bike handlebars according to the size that fits you best. When using, make sure your hands are clean to get a better grip. For maintenance, wipe them down with a damp cloth regularly to keep them clean. Avoid exposing them to extreme heat or cold for long periods as this might affect the rubber material. If you notice any signs of wear and tear, it's time to consider replacing them.
