RBST Iron Grips vs Frog Grips: Every Model Compared
Iron Claw and Iron X vs Frog Base, Fibre 3.0, Carbon, Hybrid and the Elite line: surfaces, chalk, finger holes, wrist support, sizing, price, plus a dedicated Iron X vs Frog section for high-volume bar work.
You walk into the box, look at the whiteboard, and see bar muscle-ups, toes-to-bar and 400-meter runs between rounds. Half the class is strapping on grips. Some are fingerless, some have finger holes. Some athletes chalk their grips, others don't. If you're shopping for your first pair or looking to upgrade, the options get confusing fast.
This guide compares RBST's two Iron grips with Frog Grips' full gymnastics-grip lineup, and it now includes our former Iron X vs Frog Grips article as a dedicated high-volume section. We don't declare one brand the universal winner. Instead, we compare what actually changes how a grip feels on your bar: surface, chalk use, finger holes, wrist support, sizing and price.
The Quick Answer
RBST Iron Claw ($54.95) is a fingerless silicone grip with reinforced fiber backing for everyday athletes. RBST Iron X ($59.95) is an ultra-thin fingerless natural-rubber grip with Kevlar backing for experienced, high-volume athletes. Both are designed for clean bars.
Frog Grips offers a broader range: chalk-ready Base, Fibre 3.0 and Carbon; the chalk-resistant Hybrid; and the chalkless Elite line, including a Fingerhole option. Choose based on your gym's bar conditions, your chalk habits, whether you want finger holes, and your hand measurements.
Key takeaways
- RBST keeps it simple: two fingerless grips, sorted by training level.
- Frog offers more configurations: chalk-ready, chalk-resistant and chalkless, with fingerless and finger-hole styles.
- Your bar matters most. Clean bars suit tacky or chalkless surfaces; heavily chalked bars suit chalk-ready grips.
- If you want finger holes, Frog has options that RBST's current Iron lineup doesn't.
- RBST prices are in USD; Frog's Australian store lists AUD. Compare delivered prices.
- Letter sizes aren't standardized across brands. Measure and use each brand's chart.

Two brands, two different approaches
RBST Iron lineup
Two focused fingerless designs built around clean-bar contact. Iron Claw for everyday athletes; Iron X for experienced athletes chasing higher gymnastics volume. Both include a wrist-flex strap, wrist guard, mesh carry bag and carabiner.
Frog Grips lineup
A wider selection organized by material, chalk needs and wrist design. Chalk-ready: Base, Fibre 3.0, Carbon. Chalk-resistant: Hybrid. Chalkless: Elite Lite, OG, HD and Fingerhole.
RBST simplifies the choice by training level. Frog offers more configurations for specific preferences.
Chalk-ready vs chalkless grips
This is one of the most important differences to understand before buying.
Chalk-ready
Surfaces designed to work with chalk. Frog Base, Fibre 3.0 and Carbon fall here, and they suit heavily chalked bars.
Chalk-resistant
Frog Hybrid is designed to perform on clean and light-to-medium chalked bars.
Chalkless / tacky
Intended to hold the bar without chalk on the contact face, and they generally do best on clean bars. RBST Iron Claw, Iron X and Frog Elite are clean-bar-focused designs.
With Iron Claw, chalk the backing only. Iron X needs little chalk on the front. More in our chalk vs no-chalk grips guide.
Fingerless vs finger-hole grips
Both RBST Iron grips are fingerless. Fingerless grips have no loops around your fingers, which can make transitions to barbells, dumbbells, rowing and jump ropes simpler. Finger-hole grips hold the palm material in place with finger loops, which some athletes prefer on rings and traditional gymnastics. Frog offers finger-hole versions in Base, Fibre 3.0 and Elite. If you want finger holes, Frog has options RBST's current lineup doesn't. Learn more in fingerless vs finger-hole grips.

Iron X vs Frog for high-volume bar work
Chasing bigger sets of chest-to-bar and bar muscle-ups? This is where Iron X and Frog's Elite line overlap most.
Iron X · $59.95
Ultra-thin natural rubber front with carbon-fiber texture and Kevlar backing. Fingerless, wrist-flex strap and wrist guard. Built for clean bars and big gymnastics sets.
Frog Elite Lite · AUD $90
Frog describes it as chalkless, with a softer feel, lighter build and a slim, flexible wrist strap. Elite OG and HD (AUD $108) are the other chalkless fingerless options; HD adds wider wrist support.
| Factor | RBST Iron X | Frog Elite line |
|---|---|---|
| Design intent | Thin, high-volume fingerless grip for clean bars | Chalkless models with different wrist styles |
| Finger options | Fingerless only | Fingerless, plus Elite Fingerhole |
| Wrist | Wrist-flex strap and wrist guard | Lite: slim, flexible; HD: wider support |
| Sizes | M–XXL | Lite S/M, L, XL; OG/HD/Fingerhole S–XL |
| Price | $59.95 USD | AUD $90–$108 |
| Best when | Clean bars, thin feel, big C2B and BMU sets, larger hands up to XXL | You want a chalkless Frog with a specific wrist style or finger holes |
Match the grip to your bar work
- Chest-to-bar and high-rep pull-ups: thin contact surfaces help as sets get long. Iron X is built for that volume on clean bars.
- Bar muscle-ups: you need secure wrists and freedom for the turnover. Size carefully. Too small pinches; too large can slip in the transition.
- Mixed-modal days: if gymnastics mixes with barbell work, an everyday grip like Iron Claw may feel more versatile than a thin volume specialist.
Sizing across both lineups
| Lineup | Listed sizes |
|---|---|
| RBST Iron Claw / Iron X | M, L, XL, XXL |
| Frog Base / Fibre 3.0 / Carbon / Hybrid / Elite Lite | S/M, L, XL |
| Frog Elite OG / HD / Fingerhole | S, M, L, XL |
For Iron Claw and Iron X, measure palm length from the wrist edge to the base of your middle finger: M 3"–3½", L 3½"–4", XL 4"–4¾", XXL 4¾"+. Between sizes, size up. RBST goes up to XXL. Use Frog's own chart for Frog sizing. Full steps: RBST grip sizing guide.
A grip that's too long can wrap too far around the bar; one that's too short may not cover the high-friction area of your palm.
Price comparison: what are you paying for?
Iron Claw $54.95 USD · Iron X $59.95 USD. Both include a mesh carry bag and carabiner and are hand and machine washable. On Frog's Australian store, chalk-ready models were listed at AUD $45, Hybrid at AUD $102, Elite Lite at AUD $90, and Elite OG, HD and Fingerhole at AUD $108. These are different currencies, so compare final delivered prices after conversion, shipping and regional availability.
RBST pull-up grips also carry a 6-week limited warranty against manufacturer defects (replacement only). See the product warranty.
Care and durability for any grip
RBST Iron grips
Hand or machine washable. Use a gentle cycle, avoid high heat and air-dry completely. Keep the contact surface clean and inspect stitching and straps. Full steps: grip care guide.
Frog Grips
Follow each model's care instructions, remove buildup, dry before storage, and inspect straps and closures.
For any brand, replace grips with holes, tears near the wrist, weak closures or worn-through contact material. See how long grips last.
Who should choose which
RBST Iron Claw is for: athletes new to grips or doing everyday mixed training on clean bars who want fingerless.
RBST Iron X is for: experienced athletes doing high-volume gymnastics on clean bars who want thin bar feel, including bigger hands that need XXL.
Frog is for: athletes who train on heavily chalked bars, want finger holes, or prefer a specific Elite wrist style.
Neither is for: anyone expecting a grip to replace hand care. No grip can guarantee you won't tear. See how to prevent ripped hands.
How to choose in five steps
Know your bars. Clean, lightly chalked or heavily chalked changes the shortlist immediately.
Pick fingerless or finger-hole. RBST is fingerless; Frog offers both.
Match training level. Everyday (Iron Claw, Frog Base/Hybrid) or high-volume (Iron X, Frog Elite).
Measure your palm and use each brand's chart.
Compare delivered prices in your currency, then break new grips in with lower-volume sessions.
Six common grip-buying mistakes
- Comparing brands instead of models. Surfaces differ a lot within one lineup.
- Ignoring the chalk conditions in your gym.
- Choosing on price alone instead of fit and surface.
- Skipping break-in. See how to break in grips.
- Forgetting hand care because you bought grips.
- Assuming every grip is competition-legal. Check your event's rules.
Five gym scenarios and the grip that fits
| Your situation | Start with | Why |
|---|---|---|
| Box with brushed, clean bars and a no-chalk-on-grips culture | Iron Claw or Iron X | Both are built around clean-bar contact. Pick by training level. |
| Garage gym, bars you chalk heavily every session | Frog Base, Fibre 3.0 or Carbon | Chalk-ready surfaces are designed for that environment. |
| Bars are cleaned sometimes, chalked lightly other days | Frog Hybrid, or Iron Claw with chalk on the backing only | Hybrid is listed for clean and light-to-medium chalked bars. |
| Competitor doing long sets of C2B and bar muscle-ups | Iron X, or Frog Elite Lite / OG | Thin, chalkless or tacky surfaces built for volume. |
| You love finger holes for rings | Frog Fingerhole models | RBST's current Iron grips are fingerless only. |
If two scenarios apply, let the bar you use most decide. A grip that matches your usual bar beats a grip chosen for a once-a-month event.
What to check on each listing before checkout
Product details change, and this comparison is only as good as the day it was checked. Before ordering either brand, confirm these on the live product page:
- Chalk guidance for the exact model. Chalk-ready, chalk-resistant and chalkless can sit side by side in one brand's catalog.
- Finger style. Many Frog ranges are sold as separate fingerless and fingerhole listings, so make sure the one in your cart matches what you want.
- Size range for that model. Frog's chalk-ready grips use S/M, L, XL, while Elite OG, HD and Fingerhole use S to XL. RBST Iron grips use M to XXL.
- Currency and shipping. RBST lists USD. Frog's Australian store lists AUD, and delivered cost depends on where you live.
- Warranty and returns. RBST grips carry a 6-week replacement-only warranty against manufacturer defects. Check Frog's own policy on its site.
Taking two minutes on these checks saves a return, and it saves you from learning on a WOD day that your new grips don't suit your bar.
Expert tips
- Test any new grip in a short strict and kipping set before a scored workout.
- If you train in two gyms with different chalk rules, the bar you use most should decide.
- Re-measure your palm when buying a different brand. Don't carry your letter size across.
- High-volume athletes: keep a backup pair so each pair dries fully between sessions.
