Extension additions ..
We have seen some dramatic developments in extension design in the past 12 months. A team mate of mine did some experimentation with foam and heat shrink. I copied him using balsa wood (!)
Aero testing road bike riding positions
The main purpose of this test was to gather data using an AeroPd (air speed) to compare to Garmin data (wheel speed). I failed the upload test for the data recorded on the AeroPod.
Aero testing at Minet Park
I set out compare my ENVE 7.8 front with a 5000 TL to my older 808 with a Conti TT and a Tubolito tube. The results weren’t quite what I expected.
Aero testing at Welwyn 2019
I wanted to compare the CdA of my current “tall and narrow” position to the low position that I used in the 2014 season, to see if it would be worthwhile doing another six months, over the winter, re-adapting to a low riding position.
Uvex Race 8 versus Met Drone

Having done extensive “Open Area Testing” at multiple venues, and cross-calibrated them, I’ve always wanted to validate my field-testing results directly with results from a wind tunnel session. The Wind Tunnel at the Boardman Performance Centre has made this more affordable, so I booked a session.
Options for the front end
If you go to an event and observe the riders on time trial machines you will see a wide range of front end positions. Getting the most efficient position for both aero performance and power production is the Holy Grail. In this post I attempt to give some structure to the process of finding that position ….
