Test Protocol / Input:
Rider & Setup Details:
- Rider weight: 75 kg
- Rider FTP: 340w
- Goal Watts for Test: 255w
- Overall setup all race-day: MET Drone helmet, trisuit, disc-wheel, Argon 18 E119, Vittoria G2.0 tubulars.
Test Course & Protocol:
- 5.2 km out and 5.2 km dead flat (By the Barcelona Airport, if anybody is curious)
- Total elevation for the test course is 5m.
- The course was ridden 4 times out and 4 times home.
- Loop 1 & 3 was ridden with a 1.5L empty water bottle in the front of the trisuit.
- Loop 2 & 4 without the bottle.
- The Outbound interval, was started after a 5 min break in Z1, pedaled up to 40 km/h at 255w, before starting the interval.
- The Homebound interval was started already up to speed and at 255w. This explains the slightly higher Avg HR on the home interval. See segment map below
- Wind: very low. Was stated as 5-6 km/h on local weather app, and mostly a side wind.
- Temperature: 22-25 degrees celcius
- Overall the whole test ride was 106 km and took 3h06m, which explains a slight HR creep upwards, over the test period.
Test Methodology Critics:
- Slightly short course for the test.
- Only 4 test runs is not enough to show any real significance
Initial conclusions:
- Fairly happy with the output around 43 km/h at 255w.
- Initially no benefits for me, using a plastic bottle down the front of the tri-suit. In both cases, the output was slower with the bottle.
