Hello lightheir,
I will look around for some pics … doing taxes and some projects so it might be a bit …
We had pics and data from the tests in the San Diego Low Speed Wind Tunnel but that was long ago.
I modified the Camelbak straps to get a comfortable fit over chest and abdomen … using the bladder only it sliped abound too much.
Tried making an interior pocket in the shirt but the weight of bladder and the flexibility of the shirt make it unstable.
So used the regular Camelbak and some other brands and cut off anything not needed and adjusted the straps to function on body front.
I raced it in Ironman races and it worked nicely.
I will be 89 this year so not much riding lately … just bought a C2 erg for exercise …
Last full Ironman race was when I was 76 or so … In that era I got a first in my age group in IM Florida and IM Arizona and 1/2 IM at Boise.
Long ago and far away …
You may win the most senior award on ST! Maybe Slowman can verify…
