The Definitive Guide On How To Put Grips On A Bike: Installation And Removal Techniques

Installing bike grips requires proper cleaning of the handlebar surface and the application of appropriate friction-reducing agents or mechanical locking mechanisms to ensure the grip stays secure under torque. By following precise preparation steps and utilizing industry-standard installation lubricants like isopropyl alcohol or hairspray, you can achieve a factory-standard fit that prevents rotation while riding.

Essential Preparation and Tooling Requirements

Before initiating the replacement of your bicycle grips, it is critical to categorize the type of grip you are installing, as the procedure differs significantly between lock-on grips and standard slide-on rubber grips. Lock-on grips utilize a mechanical collar with a 3mm hex bolt to secure the grip to the handlebar, whereas slide-on grips rely on a friction fit and adhesive properties. Failure to identify the grip type often leads to damaged handlebar coatings or ineffective grip adhesion.

• Essential Tools:
  
  
  • 3mm or 4mm Allen (hex) key for lock-on collars.
  • Flat-head screwdriver (for prying off stubborn old grips).
  • Utility knife or box cutter (only if you intend to destroy and discard the old grips).
  • Isopropyl alcohol (70% or higher concentration) or specialized grip glue.
  • Clean microfiber cloth or shop towel for surface preparation.
• Workplace Standards:
  
  
  • Estimated duration: 10 to 20 minutes for a full set.
  • Workspace: A stable repair stand or a secure horizontal surface to prevent the bicycle from tipping.
  • Environmental Conditions: Perform installation in a dry environment to ensure evaporation of solvents if using the alcohol technique.

Professional Installation Workflow

Step 1: Removing the Existing Grips

To remove slide-on grips without destroying them, insert a thin, flat-head screwdriver or a long zip-tie between the grip and the handlebar. Spray a small amount of isopropyl alcohol into the gap and wiggle the tool around the circumference to break the suction. Once the solvent has lubricated the interface, twist the grip firmly while pulling outward. If the grips are worn and you are installing new ones, use a utility knife to carefully slice the grip lengthwise away from your body, then peel it off to expose the bar end.

Step 2: Preparing the Handlebar Surface

The integrity of a new grip is entirely dependent on the cleanliness of the handlebar contact area. Whether you are using carbon fiber or aluminum handlebars, use a microfiber cloth dampened with isopropyl alcohol to remove all residue from previous grips, sweat, or oil. For carbon fiber bars, avoid using abrasive materials that could score the surface and create stress risers. Once the surface is clean, allow it to air-dry completely until the bar feels tacky or entirely clean.

Step 3: Installing Lock-On Grips

Lock-on grips are the industry standard for high-performance mountain biking because they prevent the grip from twisting during aggressive maneuvers. Slide the lock-on grip onto the handlebar until it is fully seated against the shifter or brake lever assembly. Once positioned, use your hex key to tighten the bolts on the lock-on collar.

Pro-Tip: Tighten the bolts in an alternating pattern if the collar features multiple fasteners to ensure even pressure distribution around the handlebar diameter.

Warning: Do not overtighten the hex bolts, as this can strip the threads in the collar or crush lightweight carbon fiber handlebars. Refer to the manufacturer's torque specifications, which typically fall between 3Nm and 5Nm.

Step 4: Installing Slide-On Rubber Grips

For non-locking grips, you must create a temporary lubricating layer that facilitates sliding but evaporates into a sticky bond. Lightly mist the inside of the new grip and the exterior of the handlebar with isopropyl alcohol. Quickly slide the grip onto the bar in one continuous motion.

Pro-Tip: If the grip stalls halfway, do not stop. Maintain momentum. If the alcohol evaporates too quickly, you will be unable to reposition the grip. Once installed, let the assembly sit undisturbed for at least six hours to allow the solvent to evaporate fully, ensuring a secure, non-slip fit.

Material Specifications and Grip Performance Factors

Managing Common Installation Failures

• The Grip Keeps Rotating: This is common with slide-on grips that were installed with oil or water instead of alcohol. Root cause is a failure of the bond. Fix: Remove the grip, clean the handlebar thoroughly with degreaser, and reinstall using only isopropyl alcohol, ensuring no contaminants remain.
• The Grip Cannot Reach Full Depth: Often caused by a vacuum effect or debris inside the grip. Root cause is trapped air or hardened adhesive. Fix: Use a compressor with an air nozzle to blow air between the grip and bar while pushing. The air cushion will allow the grip to slide on easily.
• Handlebar End Damage: Occurs when sliding a metal tool too deep into the bar. Root cause is lack of control. Fix: Use a plastic prying tool or wrap the tip of your screwdriver in electrical tape to prevent scratching the handlebar finish.

Frequently Asked Questions

Can I use hairspray to install bike grips?

Yes, hairspray was historically the standard for grip installation as it acts as a lubricant during application and becomes tacky as it dries. However, modern isopropyl alcohol is preferred because it leaves no sticky residue and is less prone to trapping moisture that could promote corrosion on steel bars.

How do I know if my handlebars are compatible with lock-on grips?

Almost all modern mountain bike handlebars feature a standard 22.2mm diameter at the ends, which is compatible with standard lock-on grips. Ensure your bars are not damaged at the ends, as any burs or deep scratches can prevent the lock-on collar from seating correctly or scratching the bar finish.

Are silicone grips installed differently than rubber grips?

Silicone grips, such as those made by ESI, are thinner and denser. They require significantly more effort to stretch onto the bar. Using a generous amount of alcohol is necessary, and they often require a "twist and shove" technique to overcome the high friction coefficient of the silicone material.

Is it necessary to use grip glue for rubber grips?

Grip glue is generally unnecessary if you use the alcohol method, which provides a stronger, cleaner bond. Grip glue should only be reserved for high-vibration applications or specific BMX setups where the rider prefers a permanent, chemically bonded connection that is difficult to remove later.
