Wind Tunnel Testing…
End of May I had the exciting opportunity to support Diego Poncelet on a wind tunnel test day in Geneva. Several different helmets, suits, appendices and positions were tested. A total of 66 sessions at 20 seconds each were recorded. We were handed a USB stick containing numerous folders with spreadsheets and two videos per…

Tuck analysis
Gaëtan Henry is a french downhill skater and physio therapist. He recently did some very interesting tuck analysis based on my scans of Diego Poncelet and Pete Connolly. Below are some of the animations which were used for the video published on our Instagram profiles. Follow this link, like and comment please. Get in touch…

Diego Poncelet
Diego Poncelet is the 2022 Downhill Skateboard World Champion. Always looking for improvements on his equipment, we adapted fairings previously designed for Pete Connolly and Azzy Skippings to fit Diego’s Ronin trucks. A few days before Diego was leaving for the final races of the season in South America, we did a full body scan…

JKMRTN
The James Kelly / Martin Siegrist longboard design collaboration project started back in 2019 with the scan of a few of James’ boards and the analysis of their concaves. Designing the concave based on measurements was a little difficult. Instead we used a simple and effective process: the concave was modelled with stacked layers of…

Damian Andrey
Damian holds the Guinness World Record for the fastest speed on a streetluge (163.88 km/h). The fusion of this body scan into a watertight, 3D printable model was demanding since the bottom / back side of his body were difficult to capture in the lying position. The Rogers Brothers luge with fairings was scanned separately.…

Pete Connolly
With an impressive speed of 146.73 km/h, Pete holds the Guinness World Record for the fastest speed standing on a downhill skateboard. In search of improvements we developped fairings for his Sabre longboard trucks. Pete spent quite some time in a wind tunnel and eventually got some help from SimScale, a company which offers an…

Jet Sigi Promodel
In 2012 and 2013 I got to redesign and tweak nearly the entire Jet lineup. And then it was time to design my new promodel with Jet. The board was supposed to be made of relatively thick veneers bonded with dry sheets of hot melt and various layers of uni directional carbon. The molds required…

TSG Pass
The Pass helmet is the realisation of my Industrial Design Bachelor Thesis project “Dawn” with the Swiss brand TSG. Certified with EN 1078 and ASTM F1952, the Pass helmet is the most popular full face helmet for downhill skateboarding.

Fuse / Bracket
The concave of the Fuse and Bracket longboards were developed by bending a lot of paper. At the time, I was not yet able to simulate the behaviour of thin layers of veneer computationally yet. Once I had the layout of the bends figured out, I transferred it into CAD. At the time, the bends…
