With a remarkable set of unique and highly-advanced properties, Seismic’s DEFCON ultra-high-rebound urethane is the fastest formula in the history of skateboard racing, bar none.
Credited with virtually every significant world speed and distance record – including the official Guinness Standup mark (91.17 mph / 146.73 kph), the official Guinness Street Luge mark (101.83 mph / 163.88 kph), the official Guinness Standup Slide mark (73.34 mph / 117.35 kph), and the Long-Distance Push Mile, Marathon, and 24-Hour Ultra marks!
Defcon’s superior energy efficiency means not just higher speeds and longer push distances, but also noticeably longer battery life and rolling range on your e-board! (If not yet available, ask your favorite e-board brands to offer pulley adapters fitted to the Turbine hub.)
Available in two finely-tuned durometers, both with predictable handling and slow, consistent wear…
– 74A Mango: Fast, smooth, grippy, and lively underfoot. An optimal balance of properties for most surface conditions.
– 76A Mint: Ideal for smoother surfaces. Very fast roll with friendlier slide characteristics. Excellent durability.

The Turbine™ core – NEW!

Integrates nearly 20 years of advanced hub R&D.
53mm tall x 46mm wide – the largest and most supportive hub ever seen in a wheel this size.
Formed from 85D fiber-reinforced thermoplastic – the toughest hub material in the industry – with robust bearing lugs.
Eight (8) contoured crossbeams (hollowed-out for lightness and aesthetics) combine with deep, wide “saddle” profile to create robust edge support and ironclad 3D mechanical lock with urethane.
Central crossbeams act as internal “turbine blades” that continuously catch and guide Defcon’s superior rolling rebound energy with perfect balance and revolutionary efficiency. Boosts both speed and e-board range to another level!
Stiff saddle walls trap and return lateral wheel flex energy to supercharge rebound out of pumps, carves, and tight corners.

Introducing Seismic Barrel Bushings in DEFCON urethane!

Liven Up Your Ride!…
with Seismic DEFCON Barrel Bushings
Deeper Lean with Truer, More Fluid Steering
Finer Control and Highly-Energetic Response

Available in five (5) color-coded durometers and two (2) precision-fit heights: 0.65-inch Medium and 0.75-inch Tall. (Additional duros coming early 2023.)

Seismic’s DEFCON ultra-high-rebound urethane has a remarkable set of unique and highly-advanced properties – and now we’ve applied it to bushings! Defcon is the fastest wheel formula in the history of skateboard racing – credited with virtually every significant world distance and speed record, including the official Guinness Standup mark. (Pete Connolly, 91.17 mph / 146.73 kph – Sept. 16, 2017, at The Top Speed Challenge in Quebec, Canada.)

A major step forward in bushing performance!

Deeper lean and truer, more fluid steering with less lateral hanger slop!
Highly-energetic yet smooth and controlled return-to-center.
Larger compression range compared to other bushing formulas in the same duro – No premature packing • Fuller wheel contact (less “outside wheel lift”)
Smoother, more linear resistance profile – Consistent feel • Advanced control

Fine-tuned dimensions for high-performance fit!

Full 1.0-inch Outer Diameter optimizes seating in finer Hanger bushing pockets.
Inner Diameter carefully calibrated for snug fit on standard Kingpin shafts.
Mold-top ends machined for exact height and superior flatness. – No “dished” end surfaces.
Two precision-fit heights…
– Medium 0.65-inch (16.5mm): Optimized fit in most modern longboard trucks.
– Tall 0.75-inch (19mm): Optimized fit in most specialty race trucks.

Note: May feel slightly softer than comparable duros in other bushings. For optimal bushing performance, do not under-tighten or over-tighten kingpin nuts. Replace bushings that show signs of excessive wear, weathering, or aging.

NEW! Seismic ANGLED TRUCK RISERS

Precision-Machined • Ultra-Low Profile • Easy to Stack

Packaged in pairs of one (1) 3-degree Riser and one (1) 7-degree Riser, with an advanced feature set never before seen in combination…
Thin ends reduced to 0.5mm-thickness for lowest-possible profile.
Mounting hole dimensions highly optimized for easy stacking. No more bent bolts!
Biomimetic “honeycomb” structure maximizes support with minimal material.

Rock Classic Lines With a Modern Roll

A high-performance ride with that retro vibe… on 3DM wheels by Seismic!

In the early 2000s, 3DM introduced big updates on classic 1970s race wheel shapes… and the results utterly dominated international slalom and downhill competition for many years. Seismic took over 3DM in 2004 and added fresh spins to the 62mm Cambria, 68mm Avalon, and 75mm Avila.

Seismic is stoked to once again offer these classic wheel shapes in a rainbow of beautiful colors poured in our Premium Clear™ formula: the best clear urethane on the market – smooth, fast, and grippy! (White and smoke color options also available.)

The 62mm by 45mm Cambria is perfect for when you want speed and grip but don’t need to go big and burly. Used on most of the boards seen in the 2005 feature film “Lords of Dogtown.” Great for all-purpose longboarding, cruising, and Old School styling, and also one of the world’s best Tight Slalom wheels.

The 68mm by 55mm Avalon is named after a legendary slalom racing site on California’s Catalina Island. Great for all-purpose longboarding, cruising, and Old School styling, and also one of the world’s best all-around slalom wheels – in the early and middle 2000s, the Avalon won more elite races than all other brands combined!

The 75mm by 65mm Avila, Introduced in 2002, is the original big, wide wheel, and the template for many race wheel designs that followed. Weighing more than 1/2-pound each, the Avilas excel on long courses due to their tremendous roll speed and inertia. Great for all-purpose longboarding and cruising, and among the world’s best wheels for racing disciplines including GS, DH, luge and beyond.

Seismic introduces Tekton™ bearings

The bearing behind the Official IGSA Downhill Speed World Record!

Boulder, CO – After more than two years in development, Seismic is proud to unveil the patent-pending Tekton™ bearing – the bearing behind the Official IGSA Downhill Speed World Record. (Click here to witness the awesome feat on YouTube.)

Said 2009 World Cup Champion Mischo Erban, who set the new record of 80.83mph last fall, “Tekton bearings roll fast, hold alignment better and stay cleaner, longer. It’s that simple!”

“The difference is the wide flange at the ends of the integrated half-spacers,” said Seismic founder/owner Dan Gesmer. “The big, flat contact surfaces square up, co-align and self-stabilize inside your wheels.”

“Once coupled, the Tektons literally block themselves from sitting or rocking out of alignment, so they stay straighter than any other bearing system ever,” Gesmer added. “Your wheels roll faster with better control, while the bearings last longer and stay quieter!”

According to Neil Sload of Focus Supply, one of the world’s leading suppliers of bearings to top pro skateboard brands, “The Seismic Tekton is by far the most technical skateboard bearing I’ve ever seen produced.”

“It wasn’t easy to find a bearing factory capable of manufacturing this design,” Gesmer continued. “The integral flanged half-spacers need to be custom-machined, not just cut from a stock steel tube.”

Tekton Bearings

Tektons should not be confused with bearings that have their inner races stretched on one side to form a simple half-spacer. Sometimes called “industrial” bearings, these have been used in pre-assembled skateboards since the 1970s, and more recently for racing, but they’re still vulnerable to misalignment.

The diameter of the Tektons’ flanged contact surfaces is up to 35% larger compared to bearings coupled with floating spacers, and up to 23% larger compared to bearings with stretched inner races. This translates to exponentially better correction for flaws in bearing seat levelness, bearing seat spacing, axle diameter and axle straightness.

“I have total confidence in their ability to push extreme speeds – 80mph and beyond!” said Erban.

Tekton bearings, rated at ABEC-7, are precisely dimensioned to provide superior alignment safeguards in all modern high-performance skateboard wheels. Features include steel balls, nylon retainers, black outer casing, removable rubber-coated steel seals with printed graphic, and a proprietary lubricant combining both oil and grease.

The inner race is stepped underneath the seal to resist contamination, and it’s stepped between the bearing and the flange to save weight. (A set of Tektons weighs the same as a set of conventional bearings with simple floating spacers.) On the side opposite the flange, the inner race extends 0.5mm to form a thin integrated washer.

Like all Seismic wheels, trucks, and decks, Tekton bearings are available from finer skate stores and online at www.seismicskate.com. No bearing spacers, axle washers, or World Record budgets required.
