PNW Components Loam MTB Bike Grips
The PNW Loam grips feature a premium trail-specific design with an ultra-tacky Happy Camper rubber that aims to absorb vibration and improve traction, even in wet conditions. The dual-pattern surface blends thin horizontal traction for a supple feel with a thicker mountain-style pattern to support the palm and reduce fatigue on long rides. Available in both Regular (30 mm) and XL (34 mm) to accommodate different hand sizes and grip preferences.
Best for: Riders seeking a balance of comfort and control, especially those who ride aggressively in mixed conditions or longer days on the trail. The XL option is particularly suitable for bigger hands or rider preference for more volume. Caution: Some riders may prefer a thinner grip if they favor more direct bar feel.
Ergon GA2 Fat MTB Grips
The Ergon GA2 Fat MTB grips use GravityControl rubber with an extra-thick diameter intended to deliver cushioning for all-mountain, gravity riders, and riders with larger hands. The soft rubber provides tactile feel and damping comfort on rough terrain, helping to reduce fatigue over long climbs and descents. Best for: Riders who want maximum cushioning and a larger grip surface, especially on demanding trails. Limitation: The thicker profile may be less suitable for riders who prefer a slimmer grip or tighter bar area.
ESI Grips Extra Chunky
ESI Grips Extra Chunky are crafted from soft, durable silicone designed for ultimate shock absorption. With a 34 mm installed diameter, these grips offer substantial vibration dampening and a comfortable ride experience, weighing 80 grams. The standard 5 1/8” length fits typical handlebars and can be trimmed to taste. Best for: Riders who prioritize long-ride comfort and reduced hand fatigue. Caution: The thicker profile may feel bulky on compact handlebars or for riders who prefer a slim grip feel.
BUCKLOS Single Lock-on Grip
BUCKLOS grips use high-quality thermoplastic rubber designed to stay comfortable over long rides. The single lock-on system and ridged turbine surface provide secure grip and better control in wet or muddy conditions. Easy installation with an aluminum alloy locking ring makes it a practical choice for quick upgrades. Best for: Riders who want reliable, one‑piece locking performance and a grippy surface in all weather. Limitation: Some riders may prefer a thicker or thinner diameter depending on hand size and bar width.
Wolf Tooth Lock-On Fat Paw Grip
The Wolf Tooth Fat Paw Grip is a silicone foam grip with an easy-to-install lock-on format and high vibration-damping. It is compatible with standard mountain bike handlebars and aims to deliver a straightforward, comfortable feel for riders who want a simple upgrade without sacrificing control. Best for: Riders who value a compact, damped grip with easy installation. Limitation: Lock-on systems may require occasional tightening to prevent slip on older handlebars.
Buying Guide: What to Consider Before You Buy Fat Mountain Bike Grips
Grip diameter and profile matter. Fat grips are typically wider to reduce fatigue but may affect bar reach and lever reach. Consider your hand size, finger length, and riding position when choosing between Regular and XL diameters.
Material and damping. Soft silicone or rubber compounds absorb more shock but can wear faster or collect grime. Durable compounds help maintain grip under wet and muddy conditions.
Lock-on versus slip-on. Lock-on designs prevent twisting, making installation and removal easier and more secure on rough trails. Slip-on grips are cheaper but may twist over time if not properly secured.
Surface pattern. Dual-pattern surfaces can offer both soft initial feel and strong palm support. Riders with long rides may prefer increased palm support to reduce fatigue.
Compatibility. Check handlebar diameter (most fat grips target 30–34 mm or 34 mm for oversized options). Ensure the grip length fits your bar width and lever reach.
Weight and length. Heavier grips damp vibration but can add weight; lighter options suit racers or climbers. Length affects how much grip space your hands have and where shifters sit on the bar.

Frequently Asked Questions
- Are fat bike grips compatible with standard mountain bikes? Yes, most fat grips designed for 30–34 mm handlebars fit standard mountain bikes with compatible lock-on collars or adapters.
- Do thicker grips reduce hand fatigue? In many cases, yes. A larger diameter can reduce pressure per unit area and improve comfort on long rides.
- Will a thicker grip affect brake levers? It can. If you ride with tight lever reach, check that the grip diameter doesn’t push your hands too far from the levers.
- How do I install lock-on grips? Slide the grip onto the handlebar, position evenly, and tighten the locking ring securely with the appropriate tool, usually a hex key.
- Are silicone grips durable for muddy trails? Silicone grips damp vibration well, but some riders report faster wear in extremely gritty conditions; regular cleaning helps extend life.
- Can I cut grips to adjust length? Some grips can be trimmed; check product specs to ensure length can be customized without compromising grip integrity.
