e-thirteen Introduces The Gen3 Grappler Mountain Bike Tire Lineup with Radial Options
PETALUMA, Calif. – e-thirteen has officially unveiled its new Grappler mountain bike tire line, headlined by a refined Flux GR Radial casing that delivers the best grip and comfort in the brand’s history. This comprehensive lineup provides professional-level performance at affordable prices across E-MTB, Trail, All-Mountain, Enduro, and Downhill categories.
The Radial Advantage: Grip Without Compromise
By developing a true radial construction and adding special features, e-thirteen has achieved several key breakthroughs in MTB tire performance.
So, what makes e-thirteen’s Radial tires one of the world’s best and grippiest MTB tires?
- 30% Larger Contact Patch: At equal air pressures, the radial casing provides a significantly increased footprint, improving traction, stability, and braking bite.
- Unmatched Comfort: It’s not just about grip. The radial construction adds a sense of “extra travel” to your bike, conforming to the terrain and absorbing micro-variations to reduce rider fatigue
- Dual Apex Stability: Unlike typical radial tires, e-thirteen’s version uses super-stiff Dual Apex Sidewall Inserts. This allows riders to run standard pressures without the excessive lateral flex common to radial competitors, and enhances rim protection. If you ride and live in a very rocky area, we still recommend increasing 15% to a little more for impact.
Engineered Rubber and Tread Tailored for Every Rider:
The Grappler MTB tire lineup utilizes two proprietary compounds and three purpose-built tread designs to eliminate guesswork:
- MoPo Compound: An extra-soft 42a durometer rubber used throughout the entire knob (base and outside). This provides maximum grip and slows tire rebound, damping vibrations for a tacky, high-confidence feel.
- Momentum Compound: A dual-compound option (50a center/42a shoulders) built for longevity and speed. It delivers 85% of MoPo’s maximum cornering grip while improving wear life and rolling speed, making it ideal for E-MTB and rear-wheel use.
Three Tread Options:
- Grappler: The most aggressive, all-condition tire featuring a 2-3-2 tread design, with big center lugs for predictable traction through lean angles, and reduced knob flex.
- Grappler RS: A 27.5” rear-optimized 2-2-2 tread with tall, steep-ramped center knobs for improved braking and faster rolling speed.
- Grappler TR: The fastest and lightest choice, sharing the RS layout but with a lower-profile center tread, offers speed and efficiency, making it perfect for hardpack and high-speed terrain.
A Simplified, Affordable MTB Tire Range
e-thirteen has scrutinized every model to ensure the lineup is easy to stock and easy to choose. The range includes the heavy-duty Flux GR Radial with Dual Apex Inserts, the supportive Flux GR gravity casing with GR Apex Inserts, and the lightweight Flux AM trail casing. All models feature two-ply construction for ample puncture prevention and Armor Weave sidewall protection.
“Riders shouldn’t have to choose between performance and price. Getting the Grappler right meant a lot of iterations, a lot of back-to-back testing against the best tires on the market, and a lot of feedback from racers who don’t sugarcoat anything. The construction we landed on is the one that beat everything we put it up against — and we’re putting it in riders’ hands at a price that respects their wallets.” — Joel Peters, e-thirteen
“More grip than ever, more tire for your money.”
The Grappler line is priced to provide an elite performance-to-value ratio,
with MSRPs ranging from just $59.95 to $79.95.

Frequently Asked Questions (FAQs)
1. What is the e-thirteen Gen3 Grappler tire lineup?
The Gen3 Grappler is a new mountain bike tire lineup from e-thirteen. In addition, it targets different riding styles such as trail, all-mountain, enduro, downhill, and E-MTB use. It offers multiple tread and casing options. These options focus on grip, durability, and performance.
2. What is the key innovation in the Grappler tire series?
The main innovation is the Flux GR Radial casing. It uses a radial construction design. As a result, it increases the contact patch with the ground. In turn, this improves traction, braking control, and overall stability compared to traditional tire designs.
3. What does radial construction mean in these tires?
Radial construction means the tire uses layers that allow more natural flex. In addition, this helps the tire adapt better to terrain. As a result, the Grappler lineup improves grip and comfort. It also helps the tire match surface changes while riding.
4. How does the Grappler improve grip and traction?
The radial casing increases the contact patch by about 30% at the same air pressure. In addition, this larger footprint improves traction, cornering stability, and braking performance. It works especially well on rough and technical terrain.
5. What compounds are used in the Grappler tires?
The lineup uses two rubber compounds: MoPo and Momentum. MoPo is a super-soft compound. It gives maximum grip and better vibration control. In contrast, Momentum balances grip, speed, and longer wear life. It also works well for E-MTB and rear-wheel use.
6. What tread patterns are available in the Grappler range?
The Grappler lineup includes three tread patterns: Grappler, Grappler RS, and Grappler TR. In addition, each pattern serves different riding needs. For example, some focus on aggressive all-condition performance, while others focus on fast rolling on hardpack trails.
7. What is the difference between Grappler RS and Grappler TR?
The Grappler RS focuses on rear-wheel use. It improves braking and rolling efficiency. In contrast, the Grappler TR is the lightest and fastest option. It works best on hardpack terrain where speed matters more than maximum grip.
8. Are these tires suitable for electric mountain bikes?
Yes, the Grappler lineup supports E-MTB use. In addition, it includes reinforced casing and the Momentum compound. These features help the tires handle extra torque, weight, and wear from electric mountain bikes.
9. What safety and durability features are included in the tires?
The tires include Dual Apex sidewall inserts and Armor Weave protection. These features reduce puncture risk and protect the rim. In addition, they allow riders to use lower pressure without too much sidewall flex.
10. What is the pricing and availability of the Grappler lineup?
The Grappler tire lineup costs about $59.95 to $79.95 depending on the model. In addition, most versions are available now. The range aims to balance performance and affordability across different riding categories.
