Good morning,
I hope this email finds you well and you're enjoying the last few weeks of our road season. During the past few months I have been working with the University of Washington and Len Brownlie (of Aerosports Research) to setup two wind tunnel sessions a year in an effort to provide folks from the Pacific Northwest with a local option at nearly half the cost of sessions at other low-speed wind tunnels. A group of five riders took part in our first session in March and we had the following results:
(Note: If the following table doesn't come through well the best result was 238 seconds of savings in a 40k TT. Average improvement was ~60 seconds.)
Rider 1
Seat height increased from 79 to 65 mm
Rider 2
Eki shrug; move back on seat; raise saddle 1.1 cm; move fwd on elbow pads; rough fabric on upper arms
Rider 3
Seat up 1 cm; armrests fwd and down; slide fwd on seat
Rider 4
Raise seat 0.5 cm; tilt head back; drop bars 17 degrees; Eki shrug
Rider 5
Raise seat 1.5 cm; slide fwd 3 cm; tilt helmet back and tuck hair in tail of helmet
Here are the details:
- Session Cost: $600 per/rider (with a max of 5 riders per session)
- What's included: ~2 hours of tunnel time, professional consulting, and a testing program desiged around your goals (e.g. equipment or position changes, various wind angles, etc.). You'll also receive a summary report and DVD of your session. (In full transparancy it took a while for our riders to receive their summary and DVD during our last session and I've taken steps to make sure this doesn't happen in the future.)
- Tunnel: University of Washington's Low-Speed Wind Tunnel in Seattle
- Consulting: Len Brownlie of Aerosports Research
Dates:
9/17/2011 - Next session, which currently has four (4) openings. I need to judge interest in the next few days to hold this slot.
3/2012 - Working on securing a date, but am looking to judge interest.
