Seismic Skate- New 2019 ALPHA Longboard Wheels

Longboard Wheels: The new Seismic Alpha 80.5 mm wheels for DH and LDP

Seismic Skate releases new 80.5 mm tall ALPHA Wheels in two widths – the 60 mm wide DH Race for fast downhill skateboarding and the 55 mm wide LDP Trim created for long distance pushing.

Both wheel models feature DEFCON™ high-rebound urethane formula in either 76A or 78A durometer and Seismic’s Fusion™ core. Let’s take a look at the specs…

The 2019 Seismic Alpha Longboard Wheels

The ALPHA Longboard Wheels are technically two different wheel models that share the same components but a different shape adapted to the discipline of longboarding they are best used for.

What joins these two models is Seismic’s pride and joy, their core, and urethane formula. The Fusion™ core is a 46 mm tall x 44 mm wide supportive hub with 8 hollowed-out support beams and a robust bearing lug made from durable 85D fiber-reinforced thermoplastic and surrounded by their DEFCON™ urethane in one of the two durometers mentioned above.

In an interview at the ISPO Longboard Embassy Seismic claimed their new DEFCON™ is faster than their BlackOps™ formula and proudly mentioned Pete Connolly’s Guinness World Record where he reached 146.73 km/h (91.17mph) rolling down on Seismic wheels at the L’Ultime Descente in Canada.

It’s been a few months now since gravity sports enthusiasts gathered in Canada to take part in the second L’Ultime Descente – Top Speed Challenge.

Top athletes from 9 different countries and in 6 categories gathered in an attempted to break the world top speed records while descending down a 2 km long track with the maximum grade of 18%.

The top speed in the inline category was reached by Game Holm and his 132.19 km/h, Cédric Touchette reached 126.31 km/h on his gravity bike, Frank William reached 150.41 km/h on his buttboard, on a street luge Damian Andrey reached 163.88 km/h and with a street sled Diego Campos Gasparelo went as fast as 159.29 km/h.

The fastest speed recorded was from Doug Anderson and his gravity car reaching a whopping speed of 164.13 km/h.

The fastest downhill skateboarder on the track was Pete Connolly who descended down the track at a top speed of 146.73 km/h (91.17mph) and beating the unofficial speed record of Kyle Wester. The fastest female skateboarder was Emily Pross who beat her own record with a top speed of 135.00 km/h.
