Iron Claw vs Bear KompleX
Fingerless silicone or a 3-hole, 2-hole, or no-hole grip from a bigger lineup? Here's how the RBST Iron Claw stacks up against Bear KompleX on materials, chalk, finger style, sizing, care, and price, so you can buy the grip that fits how you actually train.
It's the last round of a 20-minute AMRAP. Ten pull-ups, ten toes-to-bar, then a barbell waiting on the floor. Your hands are hot, your grip is fading, and the last thing you want is to fight finger loops on the way to the bar or feel your grip shift halfway through a set.
That's exactly when athletes start shopping, and Iron Claw vs Bear KompleX is one of the comparisons we hear about most. Bear KompleX is a long-running American grip brand known for its carbon, leather, and synthetic grips in 3-hole, 2-hole, and no-hole styles. The RBST Iron Claw is one focused design: a fingerless grip with a silicone front, reinforced fiber backing, and a Wrist-Flex strap with wrist guard, built for everyday athletes building their gymnastics.
Both are legitimate training tools. They just solve the problem differently. This refreshed guide expands our earlier RBST vs Bear KompleX post with real specs from both brands' own product pages, a model-by-model breakdown, sizing, care, and a simple checklist, so you can stop guessing and get back on the bar.
The Quick Answer
Choose the RBST Iron Claw ($54.95) if you want a fingerless grip with a silicone front that works best on a clean bar, fast transitions to barbells and dumbbells, a wrist guard, and sizes from M to XXL. Choose Bear KompleX if you specifically want finger holes (3-hole or 2-hole), a chalk-free carbon or Black Diamond surface for slick and powder-coated bars, or classic leather. Bear's no-hole Speed Grips are the closest match to the Iron Claw's style.

One Focused Grip vs a Full Menu
The biggest difference isn't the logo. Iron Claw is one focused design. Bear KompleX is a menu.
With the Iron Claw, you make two choices: size and color (Arctic White, Royal Purple, Pink, Blue, Black, or Peach). Everything else is set: fingerless, silicone front, reinforced backing, Wrist-Flex strap, best on a clean bar.
Bear KompleX asks you to make two bigger decisions first:
- Hole style. Bear's own guide: 3-hole for mostly bar work and the most coverage, no-hole for mixed training because it flips back fastest for barbell work, and 2-hole as the classic middle ground.
- Material. Carbon Comp, Black Diamond, Pinnacle microfiber, or leather. Each behaves differently with chalk and on different bar finishes.
So the honest comparison is Iron Claw against the specific Bear model you'd actually buy. For most athletes weighing these two, that's either the Bear Carbon No Hole Speed Grips (closest in style) or the Carbon Comp 3-Hole (Bear's coverage-first option).
Silicone vs Carbon vs Leather: How Each Grip Feels on the Bar
Iron Claw: silicone + reinforced fiber
A tacky silicone front over a reinforced fiber backing. RBST states it's best used on a clean bar. It's aimed at everyday athletes who want a comfortable, forgiving grip while they build kipping pull-ups, toes-to-bar, and their first bar muscle-ups.
Bear Carbon Comp
Bear describes it as lightweight, sticky carbon fiber using its patented material, made for slick and powder-coated bars, and says you don't need chalk. Available in 3-hole, 2-hole, and no-hole (Speed Grips), with triple stitching.
Bear Black Diamond & Pinnacle
Black Diamond is a synthetic Bear calls its tackiest material, built for powder-coated bars, and it says the grips hardly hold chalk. Pinnacle uses a 2.3 mm single-layer microfiber described as breathable, chalk compatible, and suited to rough steel bars, powder-coated bars, and rings.
Bear leather 3-hole & 2-hole
The classic option: genuine leather in tan and grey, and a thinner suede leather in black, per Bear's listing. Leather grips are the traditional "chalk them up and go" style many athletes started with.
The trade-off with any tacky surface, silicone included, is chalk. Too much chalk on the contact face can reduce grip instead of improving it. With the Iron Claw, chalk your hands and the backing if you sweat a lot, keep the silicone face clean, and brush a crusty bar before your set.
Fingerless vs 3-Hole vs 2-Hole Grips
The Iron Claw is fingerless. Bear sells all three styles, and this decision changes your workout more than most athletes expect.
Fingerless (Iron Claw, Bear No Hole Speed Grips)
Strap at the wrist and go. Coming off the rig, you can grab a barbell, kettlebell, or rower handle without pulling fingers out of loops. In mixed-modal metcons, that saves real seconds. Bear itself positions its no-hole grips as the go-to for WODs that blend gymnastics and lifting.
3-hole and 2-hole
Finger holes lock the grip in place so it can't slide down the palm, and 3-hole grips give the most coverage. Many athletes like that on high-rep bar work and rings. The cost is transitions: loops get in the way on barbells and dumbbells, and you'll flip or remove them between movements.
Rule of thumb: if your workouts look like "pull-ups, then thrusters, then row," fingerless is usually easier. If you mostly do dedicated gymnastics sessions, finger holes cost you less. Dig deeper in our guide to fingerless vs finger-hole grips.
Do You Need Chalk with Iron Claw or Bear KompleX?
Your gym's bars matter as much as the grip you buy. Match the surface to the steel you actually hang from:
| Your bar situation | Iron Claw approach | Bear KompleX approach |
|---|---|---|
| Clean bars, light chalk habits | Strong fit. Clean bar, dry hands, chalk the backing only. | Carbon Comp, Black Diamond, or Pinnacle all work here. |
| Slick or powder-coated bars | Wipe the bar and keep the silicone clean; results vary by bar finish. | Carbon and Black Diamond are specifically marketed for slick and powder-coated bars. |
| Heavily chalked shared rigs | Brush the bar before your set. | Pinnacle (chalk compatible) or classic leather fit a chalk-heavy habit. |
| Hot, humid gym, sweaty hands | Chalk hands and backing; add a wrist sweatband. | Bear says Pinnacle is designed for hot and humid conditions. |
One Bear policy worth knowing before you test-chalk a new pair: its product pages state grips can't be returned once chalked. Read more in chalk vs no-chalk grips and, if you sweat heavily, best grips for sweaty hands.
How Each Grip Handles Your Bar Work
Kipping pull-ups and toes-to-bar
This is the Iron Claw's home turf: a forgiving silicone front, wrist guard, and no loops to manage. Bear's 3-hole grips give more palm coverage for long sets if you don't mind the finger loops.
Chest-to-bar and bar muscle-ups
Both work. Size matters most here: a grip that's too long can wrap the bar and lock up during the turnover. If you're chasing big unbroken sets on clean bars, also look at the thinner Iron X.
Ring work
The Iron Claw can be used on rings, but the silicone works best when the rings are clean, so wipe them first. Bear says its Pinnacle grips excel on rings, and some athletes prefer finger-hole grips there for a locked-in feel.
Mixed metcons with barbells, dumbbells, and kettlebells
Fingerless wins on transitions. The Iron Claw and Bear's no-hole Speed Grips both let you move from rig to barbell without fighting loops.
Iron Claw vs Bear KompleX Sizing
- Iron Claw: M, L, XL, XXL. Measure your palm and use the RBST gymnastics grip sizing guide before you order.
- Bear Carbon Comp, Black Diamond, Pinnacle: S, M, L, XL.
- Bear leather: 3-hole in S–L; 2-hole in XS–L.
Bear's advice is to measure the palm across the knuckles (skipping the thumb) and, if you're between sizes, go smaller because the material molds and loosens slightly over the first few sessions. Always follow each brand's own chart. An M from one brand isn't an M from another.
Why fit matters: a grip that's too long can wrap too far around the bar and lock up, which is a real safety risk on kipping and muscle-ups. A grip that's too short won't cover the area where rips usually happen. Athletes with bigger hands get one practical advantage with the Iron Claw: it goes up to XXL.
Which Grip Fits Your Level?
Beginners and intermediates
Still learning to kip and building hand toughness? The Iron Claw is designed for exactly this athlete: forgiving silicone, wrist guard, fingerless setup, and machine-washable care.
Finger-hole loyalists
If you already love 3-hole or 2-hole grips, Bear KompleX gives you that style in carbon, synthetic, or leather. The Iron Claw won't change your mind on finger holes.
High-volume competitors
Cycling big sets of chest-to-bar and bar muscle-ups? Inside RBST, the step up is the Iron X (natural rubber, Kevlar backing, $59.95). Compare them in Iron Claw vs Iron X.
Powder-coated bar gyms
If your gym runs slick powder-coated rigs and you don't want to rely on chalk, Bear markets Carbon and Black Diamond for exactly that. With the Iron Claw, keep bar and silicone clean.
Pick Your Grip in Five Steps
Audit your bars. Clean steel, powder-coated, or chalk-crusted shared rig?
Choose finger style. Lots of barbell transitions? Go fingerless (Iron Claw or Bear no-hole). Mostly bar work? Consider 3-hole.
Decide on chalk. Light chalk and clean bars suit the Iron Claw. Heavy chalk habits suit chalk-compatible materials.
Measure your palm and use the brand's own chart. Don't guess from the letter size.
Check returns and care before your first chalky session, and plan to inspect before every workout.
Durability, Care, and When to Replace Grips
No grip lasts forever, and how you treat it matters as much as the material.
- Iron Claw: hand or machine washable per the RBST listing. Air dry and skip high heat. Keep the silicone face free of built-up chalk and grime, and store it in the included mesh bag so it can breathe.
- Bear KompleX: follow the care guidance for your specific material, since leather, carbon, and synthetics behave differently.
- Inspect every session: look for tears near the wrist, stretched or frayed straps, worn-through contact areas, and weak Velcro. Retire damaged grips; a failure mid-rep is a real safety risk.

Is Iron Claw or Bear KompleX better for CrossFit?
Neither is better for everyone. The Iron Claw suits athletes who want a fingerless, clean-bar silicone grip with a wrist guard and fast transitions. Bear KompleX suits athletes who want finger holes, a no-chalk carbon or Black Diamond surface for slick bars, or leather. Choose based on your bars, chalk habits, finger style, and fit.
What is the Bear KompleX equivalent of the Iron Claw?
The closest match in style is the Bear KompleX Carbon No Hole Speed Grips, because both are fingerless and built for mixed training. The materials differ: the Iron Claw uses a silicone front with reinforced fiber backing, while Bear's Speed Grips use its patented carbon material, which Bear says doesn't need chalk.
Is the Iron Claw fingerless?
Yes. The Iron Claw has no finger holes. It anchors at the wrist with a Wrist-Flex strap and wrist guard. That makes transitions from the pull-up bar to barbells, dumbbells, kettlebells, or a rower faster than with 3-hole or 2-hole grips, which is useful in mixed-modal workouts.
Do Bear KompleX grips need chalk?
It depends on the model. Bear says its Carbon Comp and Black Diamond grips don't need chalk and are made for slick and powder-coated bars, and it notes Black Diamond hardly holds chalk. The Pinnacle microfiber grips are described as chalk compatible. Leather grips are the traditional style many athletes use with chalk.
Can I use chalk with the Iron Claw?
Yes, but keep it off the silicone face. The Iron Claw is best used on a clean bar. If you sweat a lot, chalk your hands and the backing, brush built-up chalk off the bar before your set, and wipe the silicone clean. Too much chalk on a tacky surface can reduce grip.
What sizes do the Iron Claw grips come in?
The Iron Claw comes in M, L, XL, and XXL. Measure your palm and use RBST's gymnastics grip sizing guide before ordering. If you're unsure, the guide is a better reference than guessing, because grips that are too long can wrap the bar and lock, and grips that are too short won't protect your palm.
What sizes do Bear KompleX grips come in?
Bear's Carbon Comp, Black Diamond, and Pinnacle grips are listed in Small through X-Large. Its leather 3-hole grips are listed in Small through Large, and the leather 2-hole in X-Small through Large. Bear recommends measuring across the knuckles and going smaller if you're between sizes. Always use Bear's own chart.
Should I get 3-hole, 2-hole, or fingerless grips?
Pick based on your workouts. Bear's own guidance is 3-hole for mostly bar work and maximum coverage, no-hole for mixed training because it flips back fastest for barbell work, and 2-hole as the middle ground. The Iron Claw is fingerless, which suits metcons that combine gymnastics with barbells or dumbbells.
How much do Iron Claw and Bear KompleX grips cost?
The Iron Claw is $54.95 at rbstgearco.com and includes a mesh carry bag and carabiner. At the time of writing, Bear KompleX listed most carbon, Black Diamond, and Pinnacle grips at $54.99 on sale, with 2-hole carbon and leather 3-hole at $49.99 and leather 2-hole at $44.99. Prices change, so check current listings.
Are Iron Claw grips good for beginners?
Yes. RBST designed the Iron Claw for everyday athletes building their gymnastics skills. The silicone front is forgiving, the wrist guard adds comfort, and the fingerless setup is simple to put on and take off. As your volume grows, you can step up to the thinner Iron X if you want more direct bar feel.
Can I use the Iron Claw on rings?
You can, but the silicone surface works best when the rings are clean. Wipe or brush them before your set and keep chalk off the grip face. Some athletes prefer finger-hole grips on rings for a more locked-in feel, so ring-heavy athletes may want to try both styles.
Can I machine wash the Iron Claw?
RBST lists the Iron Claw as hand and machine washable. Use a gentle cycle, avoid high heat, and air dry. Regular washing keeps the silicone face clean and helps with odor from sweat and chalk. For Bear KompleX grips, follow the care instructions for your specific material, since leather and synthetics differ.
Do grips prevent ripped hands?
Grips can reduce friction on your palms, but no grip guarantees you won't rip. Hand care, filing calluses, correct sizing, and solid kipping technique all matter. If you do tear, stop, clean the area, and let it heal before training on it again. Our ripped-hands guide covers prevention in more detail.
Should I switch from Bear KompleX to the Iron Claw?
If your current Bear grips work and you like finger holes, there's no reason to switch for its own sake. Consider the Iron Claw if you want a fingerless grip for faster transitions, a silicone surface for clean bars, machine-washable care, or a size up to XXL that's not offered in Bear's carbon lineup.
Is Iron Claw or Iron X the better match against Bear Carbon Comp?
For everyday training and skill-building, compare Bear against the Iron Claw. For experienced athletes doing high-volume chest-to-bar and bar muscle-ups on clean bars, the closer RBST match is the Iron X, with a natural rubber front and Kevlar backing at $59.95. Both RBST grips are fingerless.
