How much faster is a TT bike vs road bike?
The BikeRadar website claims the advantage a TT bike gives you is 60-70 watts at 40 km/h, that is, it takes 270-280 watts to ride a road bike at that speed and 220 watts to ride a TT bike. Translated into seconds, a TT bike gives you 9 seconds per kilometre advantage. This is six minutes in a 40 km time trial.
What are the disadvantages of wind tunnel testing?
Disadvantages of the Open Return Tunnel
- Poor flow quality possible in the test section. Flow turning the corner into the bellmouth may require extensive screens or flow straighteners.
- High operating costs. The fan must continually accelerate flow through the tunnel.
- Noisy operation.
Why are wind tunnels so expensive?
This is actually more economical in one way – expensive and accurate scale models do not have to be made – but the tunnels are large and expensive to build and their fans consume a great deal of power. Wind tunnels are large because of an effect called choking.
What may a wind tunnel tests reveal?
A wind tunnel test shows how a tennis ball moves through the air. NASA is using wind tunnels to test the design of the a heavy-lift launch vehicle.
What can be measured in a wind tunnel?
Air velocity and pressures are measured in several ways in wind tunnels. Air velocity through the test section is determined by Bernoulli’s principle. Measurement of the dynamic pressure, the static pressure, and (for compressible flow only) the temperature rise in the airflow.
How do you get used to the TT position?
Ask a Gear Guru: How Do I Get Comfortable in the Aero Position?
- Get A Good Bike Fit. Whether you’re buying a new tri bike or putting aerobars on your road bike, you need a professional’s expertise.
- Ease Yourself In On A Trainer.
- Use The Terrain As A Guide.
- Some Of Our Favorite Aerobar Setups.
Is aero position comfortable?
Ask your friends and training partners who they use and what their experience was with them. A textbook aero position may be tolerable for a sprint or Olympic distance race, but for longer events you need to be comfortable on your aero bars. Sometimes that means a less aggressive position.
Why are triathlon bikes heavier?
A triathlon bike is heavier than a road bike by 2- 4 lbs or 1 to 2 kg. The reason is that the aim is to make a triathlon bike more aerodynamic rather than lightweight as it is in road bikes. The triathlon bikes come with bigger aerofoils and bigger frames than the road bike.
Are some triathlon bikes faster than others?
There are only two ways that one triathlon bike is faster than another: It either has impeccable mechanical function and predictable handling while fitting perfectly to help the rider perform better, or the machine itself can go faster in a straight line.
What determines a tri bike’s straightaway speed?
And when it comes to tri bikes, aerodynamic resistance more than any other factor determines straightaway speed. We took four cutting-edge bikes ranging from totally integrated to nearly stock to compare their performance across all categories.
What makes Orbea’s new Ordu a true triathlon-first fit?
Orbea ditched antiquated road-style TT geometry and replaced it with a true triathlon-first fit scheme. In addition to a steep seat tube angle—a first for Orbea—the all-new Ordu’s front end is situated for aggressive yet attainable positions. It uses an adjustable rotating stem to affix the aerobar to the frame.
