Seismic Delta 78.5mm Longboard Wheels

Massive. Grippy. Fast as hell. The new Seismic Delta wheels are a downhill racers dream...

But not only them! Whilst at 78.5mm (the ever important half a millimetre) they might not fit under any old deck... anyone who can fit them would certainly feel the upgrade.

I'm thinking distance-folk, hard-carvers, surfskaters, beachfront-cruisers, dropthrough-afficionados, and anyone in between.

These things roll fast. Really fast. Poured from Seismic's new G-LOC urethane, building on what was already the fastest compound in the world.

• Yellow 73.5A (that important half a durometer) - the softer, grippier option. If you want to slide these downhill, you better be sure of yourself and your weight distribution! But when it comes to the highest level, these will have the highest braking power and best performance.
• Green 75.5A (oh yes) - lighter riders and smoother roads call for the green, slightly harder version. Super fast and slightly more forgiving when sideways. Still unreasonably grippy.

The fancy new urethane works with the FUSION core (as seen on the Seismic Tailwind) - a massive 46x44mm hard core that is designed to catch and guide the amazing rolling rebound of the wheel to further enhance speed and acceleration.

Stiff core walls keep the big, soft lips supported ensuring high rebound for pumping and feedback during slides.

The massive 67.5mm (you guessed it) contact patch is pretty much as big as it gets, and translates to insane grip and rollover.

Seismic really are out there trying new things and bringing out new products that are consistently proving themselves on podiums worldwide in multiple disciplines.

The Seismic Delta wheels are no exception and you'll see them in most serious downhill finals anywhere. Are they necessary on your longboard for a bit of carving about? Honestly, probably not. But are they bloody amazing on it? Oh yes they are.
