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.
The standard method is to measure height from the ground and off-set of the saddle nose from the centre line of the bottom bracket. This works well on a single bike but is not ideal when trying to replicate the back-end geometry between different bikes. Here’s an alternative method that I use …..
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.
If you are doing high end intervals ERG mode isn’t always what you need. There is a way to disable ERG mode in Zwift without having Zwift change the turbo resistance if the terrain changes e.g. the incline changes or you ride over a bit of “feature landscape” like a wooden bridge section. It does mean manually creating a .zwo …
I book a three hour slot at Newport Velodrome twice a year. I use these to validate my “open field” test results and to refine options. I book November and February as a rule, something to do with the weather. It gets a bit too cold to test in a skin suit once the clocks go back.
Not an aero post this week. I thought I’d share the Excel spreadsheet that I use to plan and record my training and events schedule. I’ve just updated it to run from November 1st 2016 to the end of 2017.
A few weeks ago I was invite to participate in one of Mark Florence’s series of Cycling Time Trial Podcasts. One of the questions that came up was how did I come up with the name “FloatAero”? When I was think about a name for the service I started from my existing web site address for Formic Intelligent Training Labs …
4th October 2016 Another good morning for testing, early before the wind got up. Tested my race set-up from last Sunday (Nopinz skin suit and trip socks) with the AeroHead helmet and then the Bambino. When I used the Nopinz skin suit and trip socks at the Cambridge Chrono earlier in the year my CdA came out a bit higher …
2nd October 2016 VTTA Rocco memorial 25 this morning on H25/1. I was hoping to make top 10 but came out as 14th on standard, 1:02:12 with an average power of 174 watts and a CdA of roughly 0.1760, which is slightly lower than I get when I test at Hillingdon in race kit, but then there is no traffic …
