I received my Svelt RAR rear with a new 12/12 cross hub instead of the 2/1 (16/8). So I took the opportunity to do a final wheel test to validate the hypothesis of the importance of the spokes.
On the program,
The same test climb of the Salbert and 3 wheels:
Edge Carbone Wheel test 4 with Ultremo ZX tire, Rar Svelt tubular Veloflex tires and Fulcrum 7. I took the Fulcrum 7 again to confirm the rather poor results obtained during the previous test. Once again, I invite buy phone number list new readers who come across this post first to read the previous ones to fully understand the history and test conditions. TEST 1 then TEST 2 then TEST 3 .
Today’s weather is perfect for late September. Sun, no wind, and a temperature of 18 degrees. It’s very close to previous tests.
I start as usual with a first warm-up climb with progressive acceleration with the EDGE tires. Wheel test 4 I get 289 W SRM for 290 W theoretical. Within the norms once again. I then start the test protocol with accelerations of 30s every 2 minutes. I toughen it up a bit by producing a big acceleration standing on the pedals @800 watts for how the internet of things can save our environment the first few seconds. Always with the aim of highlighting the low inertia of the wheels to accelerate. I get 311 W SRM for 310 watts theoretical. Now it’s time for the Svelt and unfortunately I quickly become disillusioned with 313 W SRM for 309.5 watts measured. Here I am again with 2 to 3 watts lost compared to the Edge. I start again to be sure and I get 306 W SRM for 302.5 theoretical…
Which had new tubulars with good results
To complete I replace the SVELT rear wheel again with my Edge rear wheel and this time I get 1.5 w more than the theory…. again within the standards and confirming the problem on the SVELT rear wheel. Informed european union email list observers will have noticed that this acceleration protocol makes me lose watts/theoretical compared to a progressive climb seated at 100%. Yes it’s amazing but the results speak for themselves. Going from 20 to 30 km/h while standing for a few seconds degrades the overall SCX on the climb and at 30 km/h it starts to play. There was no such loss phenomenon in the previous tests because I was climbing and accelerating while sitting.
