How to replace bicycle hand grips
You will require the following tools for this job:
A pair of scissors or a utility knife.
A small flat-head screwdriver (if your grips have lock rings).
Soapy water or Isopropyl Alcohol (IPA) and a rag.
Hairspray to fit the new grips.
Remove the old grips
If your grips have lock rings, locate the small screw on the underside of each grip and use the screwdriver to loosen and remove them. For grips without lock rings, you can usually remove them by hand. If they're stuck, you can carefully use a flat-head screwdriver to pry them off, taking care not to damage your handlebars. If they are really stuck, you may need to cut them off.
Clean the handlebars
Use IPA or soapy water to clean the handlebars thoroughly. This will remove any dirt, grease, or residue from the old grips.
Install the new grips (regular)
Apply a small amount of hairspray to the inside of the new grips. This will make it easier to slide them onto the handlebars. Hold the grip at an angle and carefully push it onto the handlebar, working your way around until it's fully seated. Make sure it's snug and aligned properly.
Install the new grips (lock-ons)
If your new grips have lock rings, slide them over the grips and tighten the screws using a screwdriver. Ensure that they're snug but not overly tight, as overtightening can damage the grips or handlebars.
Adjust and test
Once the new grips are in place, adjust their position to your liking. Take a moment to test their fit and comfort by gripping the handlebars and making sure they feel secure.
You may need to wait before riding if there is excess wetness that needs to dry under the grip.
