Please complete the short form below to start the discussion about your aero testing. Rates for local testing at the San Diego Velodrome are $150/hour with a two hour minimum then billed in 1/2 hour blocks. A velodrome membership or track experience is not necessary. Out of town rates are on a case by case basis.
Prior to the test day I like to meet to configure the sensors on your bike. There is no charge for this however, if we don’t do it, bolting on the sensors on location becomes part of your billable hours. If your bike has a standard round handlebar or base bar and an existing Garmin mount, this could be very quick. But usually not. It’s better to have some un-rushed time to get the sensors mounted carefully and correctly.
Please plan to bring all the items you wish to test and plan to be able to make adjustments to the bike on site. I can make simple changes with you – non-integrated spacers, handlebar and aero extension angles, etc. If your bike has integrated everything, you will be responsible for the adjustments. Bringing a mechanic with you can speed up the process. I can provide you with a local mechanic if needed (they will bill directly). You are also welcome to bring someone with you to help with notes, photographs, etc.
To be most effective, aero testing must be measured at the speeds you will be needing the results. In other words, if you are testing for a time trial or triathlon where your expected speed is 25mph/40kph then we have to test at 25mph/40kph. If your expected speed is 30mph/48kph then we have to test at that speed. This means you will have to be able to hold those efforts for about four minutes per run. Please plan accordingly. When I was testing myself for a six hour time trial, I could do those speeds all day. When testing for a 2k pursuit, basically full gas, I had to plan the number of runs more carefully.
On the track we will have a timing tape and the system will record your CdA and head/chest height for every lap, about 30 seconds. A four minute run gives us about eight laps which is enough to get you settled in and the air flowing over you and your bike in a repeatable fashion. We generally will use the cleanest six of the eight laps. If you, or the local conditions, are more variable, the efforts may need to be a bit longer.
On site we will have raw CdA numbers that work well for comparison purposes. Is A faster than B? Is C faster than A? Etc. After the session, we will have a call to review the results and you’ll receive a spreadsheet with all your data. There is no charge for this call.
