Grips are the only part of the bike your hands ever touch. Get the diameter, the attachment style and the compound right and you stop thinking about them — get them wrong and you feel it in your hands for the rest of the ride.
Grip Sizing: The Numbers That Matter
Three measurements define a grip: the inner diameter that decides what bar it fits, the outer diameter that decides how it feels in your hand, and the length.
Inner Diameter — Does It Fit Your Bar?
Mountain bike bars come in two grip sizes: 22.2mm (7/8") is the adult standard, and 19mm (3/4") is used on kids' and junior bikes. Check your bar before ordering — this one isn't negotiable.
Outer Diameter — How It Feels
Thinner grips give a more direct read of the bar, which helps on technical trails. Thicker grips spread the load and soak up more buzz, which riders with larger hands tend to prefer. Most Funn grips sit at 30mm; the Holeshot goes to 31mm for a fuller hold.
Length and Grip Shifters
Adult grips run around 130mm. If your bike uses a twist shifter, you need a shorter grip on that side to make room for the mechanism — sold as twist-shift specific pairs, with one short grip and one full-length.
Every Funn Grip, Compared
| Model | Bar fit | Outer Ø | Length | Attachment | Price |
|---|---|---|---|---|---|
| Hilt | 22.2mm | 30mm | 130mm | Single lock-on | $16 |
| Holeshot | 22.2mm | 31mm | 130mm | Single lock-on | $17 |
| Combat II | 22.2mm | 30mm | 130mm | Dual lock-on | $18 |
| Hilt JR | 19mm | 26mm | 115mm | Single lock-on | $12 |
Junior bars are not just narrower — the bar ends are 19mm instead of 22.2mm, so adult grips physically will not fit. The Hilt JR is built at 19mm inner, 26mm outer and 115mm long to suit smaller hands.
Hilt JR Lock-On Grips
The Hilt scaled down for groms — 19mm inner, 26mm outer, 115mm long, in eleven colours. Pairs with the Speedrun junior bar.

Lock-On
An alloy collar clamps the grip to the bar so it cannot twist, whatever the weather. Funn's Hilt and Holeshot use a single clamp on the inboard side, which keeps weight down and leaves the bar end free; the Combat II uses a clamp at both ends.
Slip-On
No collar, no hardware — the grip slides straight onto the bar. Lighter and cheaper, but it relies on friction alone, so it can creep or twist once water gets underneath. Fine for commuting and casual riding; most trail riders want a clamp.

Hilt Lock-On Grips
Single lock-on, 96g, with an outer bump-stop that shrugs off impacts. Eleven colours, 30mm diameter.

Compound decides how a grip feels on day one and how it holds up a year later.
| Material | Strengths | Trade-off |
|---|---|---|
| Rubber | Consistent grip wet or dry, hard-wearing — used across the whole Funn range | Heavier than foam |
| Foam | Lightest option, excellent vibration damping for long days | Wears through quickly in rough conditions |
| Silicone | Cushioned, holds well with gloves in the wet | Tears more easily than rubber |
| Leather | Classic look, develops a patina, popular for commuting | Least grip once it's wet |
Choosing Your Grip
Start with the bar. 22.2mm or 19mm — everything else is preference, this isn't.
Then match the riding. Technical and aggressive: thinner, lock-on, firm compound. Long days: thicker, more damping. Racing: a plush compound that fights fatigue, like the Holeshot's triple-fin underside.
Expect to experiment. Grips are the cheapest fit change you can make, and most riders only find their preference by trying two or three.
Replace them before they're slick. Worn tread, splits at the lock ring or any twist on the bar means it's time. Lost or damaged a collar? The alloy clamping rings for Hilt and Holeshot are sold separately.
Holeshot Lock-On Grips
Two years in development with our elite racers — a deep, plush compound, triple-fin underside and a hardened end section. 31mm, eleven colours.

Conclusion
Fit first, then feel. Confirm the bar diameter, pick lock-on or slip-on based on how hard you ride, and choose a thickness that suits your hands. Get those three right and your grips become the part of the bike you never think about again.
