Spanish skateboard racing legend Diego Poncelet became the fastest downhill skateboarder in history in late September 2026, when he set a new Guinness Book of World Records mark for top speed by rolling 94.34 mph (151.83 km/h) down the famous Route du Port hill in Les Éboulements, Quebec, Canada.
Diego used Seismic 90mm Megawatt prototype wheels and Fullspin 7-Ball Pro Spec bearings to best the prior record holder, the late Pete Connoly, by a full 3.5% margin.
“Next-level wheel and bearing tech was mission-critical,” said Poncelet. “Seismic poured a custom run of Megawatt wheels specifically for this record attempt, using a prototype ultra-high-rebound urethane compound. Combining these wheels with Seismic’s state-of-the-art ceramic bearings helped me squeeze every last bit of speed out of the hill. I broke my personal best on the very first test run, and I reached 151.83 only a few runs later!”
Other aspects of Poncelet’s meticulous preparation included extensive wind-tunnel testing to perfect his tuck; specialized strength and mobility training; and custom development of aerodynamic helmet, speed suit, and shoes.
Poncelet rolled on Seismic’s 90mm Megawatt wheels and Fullspin Pro Spec bearings, mounted to trucks fitted with Seismic’s Defcon bushings and a deck topped with Seismic’s Lokton grip tape.
“We’re beyond stoked that Diego chose Seismic for the mission-critical components of his record-smashing setup.” – Daniel Gesmer, founder and owner of Seismic Skate Systems
