Bike grips are an essential component of a bicycle, providing a comfortable connection between the rider and the steering. They are subject to wear and tear and need to be replaced from time to time. The process of replacing plastic bike grips involves removing the old grips, cleaning the handlebars, and installing the new grips securely. This can be done using various methods, depending on the type of grip, such as lock-on grips or slide-on grips, each with its own set of tools and techniques. The condition of the grips and the rider's comfort are key factors in determining when to replace them.

What You'll Learn
Recognising when grips need replacing
The lifespan of a bike grip varies depending on usage, conditions, and the quality of the grip itself. However, there are some tell-tale signs that indicate it's time for a replacement.
Over time, all grips will thin out, especially where your palms apply the most pressure. This can cause discomfort during rides, leading to hand fatigue, numbness, or pain. If you experience these symptoms and they're not related to other factors like bike fit or riding position, it's likely due to worn-out grips.
Another sign that your grips need replacing is if they become sticky or difficult to slide off. This can happen over time as the grips wear out or if they were not properly secured when installed. In some cases, they may even need to be cut off with a blade if they're too damaged to slide off.
Additionally, you may want to replace your grips simply for aesthetic reasons or to add some customisation to your bike. There are various ergonomic shapes and different colour options available on the market, allowing you to add a personal touch to your bicycle.
It's important to recognise these signs and replace your grips when necessary. Not only will this improve your comfort while riding, but it will also ensure you maintain a proper grip on the handlebars, enhancing your control and safety during rides.

Removing old grips
If your bike has lock-on grips, you will need to loosen the grip's bolt or bolts with an Allen wrench. Locate the bolts at the ends of the grips and use the correctly sized Allen wrench to gently loosen them enough to disengage the lock mechanism. You do not need to fully remove the bolts. Once the bolts are loosened, you can grasp the grip and slide it off the handlebar.
For slide-on grip models, you will need a flat-head screwdriver. Carefully insert the screwdriver between the grip and the handlebar, being cautious not to damage the grip material or the handlebar. You can also try using a window cleaner or hand sanitiser/alcohol gel to lubricate the bars and make the removal process easier.
If you have an OEM stock plastic throttle, the grip may be vulcanized to the throttle tube, making it difficult to remove without damaging the grip. In this case, it may be best to replace the throttle tube with an aftermarket aluminum one.
For conventional grips, the easiest way to remove them is by cutting them out with a box cutter. Start by cutting any safety wires, then cut along the length of the grips and remove them. This method will damage the grips, so if you plan to reuse them, you will need to put in more effort to remove them without cutting.

Cleaning the handlebars
To replace plastic bike grips, you will first need to remove the old grips, which may prove difficult. To do this, you can use a flat-head screwdriver, prying between the grip and the handlebar to avoid damaging the handlebar. You can also use a can of WD-40 and a window cleaner.
Once the old grips are removed, you should clean the handlebars thoroughly. This is an important step as it ensures that your new grips bond securely. To clean the handlebars, you will need a contact cleaner (preferably acetone), sandpaper, a clean rag, and possibly a wire brush or scouring pad.
- Start by using the sandpaper to remove any built-up grime or residue from the handlebars. Sand down any rough areas and ensure the handlebars are smooth and free of dirt and grease.
- Next, use the contact cleaner or acetone to wipe down the handlebars. Soak a clean rag with the cleaner and thoroughly wipe the handlebars, ensuring no grime or grease is left behind. You can use a wire brush or scouring pad for any stubborn areas.
- Once you have finished cleaning, ensure the handlebars are completely dry before proceeding to the next step of installing the new grips.
- It is important to note that you should not use oil or lubricants on the handlebars as this can interfere with the adhesion of the new grips. If you need to lubricate the handlebars to remove the old grips, be sure to clean the handlebars thoroughly afterward to remove any lubricant residue.
- You can use a degreaser to ensure that the handlebars are free of any grease or oil residue. Spray a small amount of degreaser on a clean rag and wipe down the handlebars, ensuring they are completely clean and dry before installing the new grips.
By following these steps, you will ensure that your handlebars are clean and ready for the installation of the new grips, providing a secure bond and an improved riding experience.

Installing new grips
The process of installing new grips depends on the type of grip. Classic, rubber grips are pushed directly onto the handlebars. Lock-on grips, on the other hand, are designed for ease of installation and secure handling. They are kept from twisting with a small bolted clamp on the inside or both the inside and outside of the grip.
Slide-on grips
To install slide-on grips, you can use a lubricant such as WD-40, hand sanitiser, alcohol gel, or window cleaner to make the process easier. You can also use water, but this may not evaporate as quickly. Once you have applied the lubricant, simply slide the new grip onto the handlebar.
Lock-on grips
To install lock-on grips, first loosen the grip bolt(s) with an Allen wrench. You don't need to fully remove the bolts, just loosen them enough to disengage the lock mechanism. Make sure to do this on both sides if your lock-on grips have bolts at both ends. Then, slide the grip onto the handlebar. Finally, tighten the bolts alternately and evenly, noting the maximum torque (if specified) to avoid over-tightening.
Once you have installed your new grips, give them a good twist or tug to make sure they are securely attached. If the grips rotate or slide when force is applied, you may need to loosen the bolts, reposition the grip, and then retighten.

Lock-on vs slide-on grips
Lock-on grips are designed for ease of installation and secure handling. They are attached via a clamp mechanism, which allows for quick and simple attachment or removal of the grip. This makes it easy to swap out for different styles or sizes. Most lock-on grips use two different rubber compounds: a harder compound for the base and a softer rubber on the outside. They are usually more expensive than slide-on grips but provide added security and convenience. Lock-on grips are an excellent choice for riders who require a stable, reliable grip on their handlebars and who value durability and ease of use.
On the other hand, slide-on grips are a popular option for cyclists due to their simplicity and affordability. Slide-on grips are designed to slide onto the handlebars and are secured in place by friction, glue, and/or wire. They are often made from soft, pliable materials, which provide a comfortable, cushioned grip. However, one drawback of slide-on grips is that they can rotate or shift over time, particularly with heavy use or in wet conditions. This can cause the grips to loosen or even slide off the handlebars, creating a dangerous situation.
When it comes to removing old grips, slide-on grips may be more difficult to work with. They can stick firmly to the handlebars and require some force to remove. A flat-head screwdriver can be used to pry the grip up from the handlebar, but this may scratch the bars. Lock-on grips, on the other hand, can be easily removed by loosening the bolts with an Allen wrench and then sliding the grip off.
In terms of comfort, some riders find that lock-on grips, with their added layer of hard plastic, are not as comfortable as slide-on grips. Additionally, the outside clamp on some lock-on grips can cause discomfort and pain in the hand during long rides. Slide-on grips, made from soft, cushioned materials, may provide a more comfortable grip for some riders.
Ultimately, the choice between lock-on and slide-on grips depends on the rider's preferences, budget, and specific needs. Lock-on grips offer convenience, stability, and ease of installation, while slide-on grips provide an economical and minimalistic option with a comfortable, cushioned grip.
