N+1, the full scientific rationale

In the name of science (but mostly marketing) I recently landed the gig of pedalling and posing in a wind tunnel. I got a call from 220Triathlon asking if I’d be interested in a day’s work being prodded, poked, photographed and tested at the new Boardman Performance Centre in Evesham.

The morning was spent with a physiologist who carried out a biomechanics analysis of me. I had a bunch of electrodes stuck to my body and rode a Watt Bike with state-of-the-art pedals to analyse every conceivable force in my pedal stroke, while sat on a pressure-sensitive saddle to electronically map every squeak of my bum. It produced a wealth of information – probably more data than was needed to send man to the moon, and certainly more than I would know what to do with. But nonetheless, it was pretty cool to geek out and have an insight into all the technology that’s being used by professional cycling teams these days.

The afternoon was spent playing in the wind tunnel.

The real-time feedback was incredible. You can see from the image above that there was a screen on the ground in front of me. This displayed a side-on profile (with a baseline silhouette) and gave a reading for my current aerodynamic drag (CdA). Making small adjustments to my position told me the difference this was making to my drag.

All of this data was being analysed by the technicians in the lab. We then ran a series of tests trying out different positions. For this they used a Boardman rig, partly as it was easier to make quick changes but also because they understandably wanted to get their branded bike in the magazine. They also had a selection of helmets for me to try.

There were a few quick fixes to improve my position, and others that may justify n+1 bike purchases. More on that in future blog posts!

As well as appearing in 220Triathlon, it appears I’m the also face (or more accurately the legs) of the new Boardman wind tunnel website. Luckily my face isn’t taking it too personally.
