How to Install & Change Bicycle Handlebar Grips
New grips can refresh your bike's feel and comfort. Learn how to install slip-on and lock-on grips, remove old ones, and avoid common mistakes.
Worn, torn, or slippery grips make riding less comfortable and less safe. Replacing them is straightforward once you know the type and technique.
The short answer: Slip-on grips need a lubricant (rubbing alcohol, soapy water, or hairspray) to slide on, then they dry and grip. Lock-on grips use a clamp and bolt—no glue, easy to remove. Standard MTB bar diameter is 31.8 mm; older bars may be 25.4 mm. Check your bar diameter before buying.
Here’s how to install and remove both types.
Grip Types: Slip-On vs Lock-On
Slip-On vs Lock-On Grips
| Type | Installation | Removal | Best for |
|---|---|---|---|
| Slip-on | Lubricant to slide on, dries to grip | Cut off or compressed air | Lightweight, simple |
| Lock-on | Slide on, tighten clamp bolts | Loosen bolts, slide off | Easy swap, no glue |
Handlebar diameter: Most modern mountain bikes use 31.8 mm (sometimes labeled 1-1/8”). Older bikes may use 25.4 mm (1”). Road drop bars are typically 31.8 mm at the clamp. Measure your bar or check the manufacturer specs.
How to Install Slip-On Grips
What you need: New grips, rubbing alcohol (or soapy water, or hairspray), rag.
Steps:
Remove old grips — See removal section below.
Clean the handlebar — Wipe off dirt, old adhesive, and grease. A clean surface helps the new grips stick.
Apply lubricant — Pour a small amount of rubbing alcohol (or soapy water, or hairspray) inside the new grip and on the bar. Don’t use oil or grease—they won’t dry and the grip will slip.
Slide the grip on — Work it on with a twisting motion. It should slide easily. Position it where you want it (many riders leave a small gap at the end for bar plugs).
Let it dry — Rubbing alcohol and soapy water evaporate in minutes. Hairspray takes a bit longer. Once dry, the grip should stay put.
Install bar plugs — Insert bar-end plugs to protect the bar and your hands in a crash.
How to Install Lock-On Grips
What you need: New lock-on grips, hex key (usually 2.5 or 3 mm).
Steps:
Remove old grips — Loosen the clamp bolts and slide off.
Clean the bar — Wipe the bar where the grips will sit.
Slide the grip on — No lubricant needed. Position it.
Tighten the clamp bolts — Use a hex key. Tighten evenly (alternate between bolts if there are two). Don’t overtighten—you can crack the clamp. Snug is enough.
How to Remove Grips
Removing Lock-On Grips
- Loosen the clamp bolt(s) with a hex key.
- Slide the grip off. If it’s stuck, twist while pulling.
Removing Slip-On Grips
Method 1: Compressed air
- Insert a thin nozzle (e.g. from a bike pump or compressor) under the grip edge.
- Blow air between the grip and bar. The grip will loosen and slide off.
- Works well and preserves the grip for reuse.
Method 2: Flat screwdriver and lubricant
- Lift the grip edge with a flat screwdriver.
- Squirt rubbing alcohol or water between the grip and bar.
- Twist and work the grip off.
Method 3: Cut off
- Use a utility knife to slit the grip lengthwise.
- Peel it off. The grip is destroyed, but removal is quick.
Common Mistakes
- Using oil or grease for slip-ons — They won’t dry; grips will slip. Use alcohol, soapy water, or hairspray.
- Wrong bar diameter — Grips won’t fit or will be loose. Check 31.8 mm vs 25.4 mm.
- Overtightening lock-on clamps — Can crack the clamp. Snug is enough.
- Not cleaning the bar — Dirt and old residue prevent a secure fit.
Handlebar Grips FAQs
What is the standard handlebar diameter for mountain bikes?
Most modern mountain bikes use 31.8 mm (1-1/8") handlebars. Older bikes may use 25.4 mm (1"). Check your bar or manufacturer specs before buying grips.
What can I use to install slip-on grips?
Rubbing alcohol, soapy water, or hairspray work well. They lubricate for installation and then evaporate or dry so the grip sticks. Don't use oil or grease—they won't dry and the grip will slip.
How do I remove stubborn slip-on grips?
Compressed air under the grip edge works best—it loosens the grip without damaging it. Alternatively, slip a screwdriver under the edge, add rubbing alcohol or water, and twist the grip off. As a last resort, cut the grip with a utility knife.
What's the difference between lock-on and slip-on grips?
Lock-on grips have a clamp and bolt—they slide on and tighten, no glue or lubricant. Slip-on grips slide on with a lubricant (alcohol, soap) that dries to hold them in place. Lock-ons are easier to remove and replace.
Summary
Slip-on grips need rubbing alcohol, soapy water, or hairspray to slide on, then they dry and grip. Lock-on grips use a clamp—slide on and tighten. Remove slip-ons with compressed air or a screwdriver and lubricant; remove lock-ons by loosening the clamp. Check bar diameter (31.8 mm or 25.4 mm) before buying.
