Hello all!
I’m a student conducting market research on cycling wheels. As a part of the research, I’m surveying how much cyclists know about bike wheels. I’d very much appreciate it if you could spare 2-3 minutes to complete some True or False questions about road bike wheels. You will get to see your score at the end and see the correct answers if you wish.
Here is the link to the survey if you are interested:

Thank you all!

This reads more like a quiz than survey. However, I'd like to point out that some of these are trick questions, and some of the supposed "correct" answers are actually not correct:
Tire rolling resistance depends on the amount of sealant, or the type and thickness of the inner tube. Multiple tests have shown that standard clinchers with latex tubes have the same rolling resistance to tubeless tires with about 1 oz. of sealant. So a tubeless tire with excess sealant may actually have more more rolling resistance than the same tire with a latex tube.Question 10/30
"Tubeless tires are considered superior to clincher tires in terms of performance because they create less friction which improves rolling resistance."
Correct answer: True
The correct answer is False: increasing spoke tension does not improve power transfer or responsiveness (stiffness). In fact, increasing spoke tension may actually decrease stiffness, due to inducing a buckling action in the rim.Question 14/30
"A higher spoke tension improves power transfer and responsiveness."
Correct answer: True
Wheels of any kind (excluding the tire) have so little vibration damping that any difference between the damping properties of carbon and aluminum are meaningless. There have been tests in which the identities of wheels have been hidden from riders, and the riders have been unable to reliably distinguish between wheels with different rim materials and depths.Question 20/30
"Carbon wheels provide better vibration damping compared to aluminum wheels."
Correct answer: True
This is a bit of a trick question. Deeper rims are typically more aerodynamic than shallower rims, and it is easier to make deeper rims with carbon - but the material itself does not make wheels more or less aerodynamic. There are some aluminum wheels which are more aerodynamic than some carbon wheels.Question 21/30
"Carbon fiber wheels are generally more aerodynamic than aluminum wheels."
Correct answer: True
This is false. This has been specifically tested. One of the tests can be found here: https://www.sheldonbrown.com/rinard/wheel_index.htmlQuestion 22/30
"A higher spoke tension increases the lateral stiffness of a bicycle wheel."
Correct answer: True
This is a trick question. Tubeless tires are no more resistant to punctures than tube-type tires. However, punctures can be self-sealing with tubeless tires so that one may continue riding without having to repair the tire.Question 30/30
"Tubeless tires are generally more puncture-resistant than clincher tires."
Correct answer: True
Mentioned just above but indeed some responses appear erroneous.
And would add this one
It’s not air volume it’s casing tension (long story short surface aera that is fonction of max width). You could fill the “inside” of the tire, remove volume, it wouldn’t change anything.

More than you by the sound of these questions.Won wrote:How much do you know about wheels?

I had given this one a pass, but you're right, a tire is not simple air spring, and compliance is not a question of air volume. On the other hand, it could be argued that a higher volume tire (or rather, a larger cross-section tire) allows using lower pressure, which in turn results in lower casing tension, and therefore more tire compliance. In that way, you could say a larger cross-section tire can indirectly provide more tire compliance.C36 wrote: ↑Tue Jun 06, 2023 9:54 pmMentioned just above but indeed some responses appear erroneous.

I thought the OP would need to study the tubular thread and wheel building thread but it's about marketing, no wonder the questions are somewhat shallow.

I got 27/30, failed 3,4, and 10 mentioned above.
Not all questions are worded correctly IMHO, plus 30 is a bit too many.
