"Does a quick release lever change the adjustment of a hub? Yes or No is not important, how do you test to verify your answer is important."
With most hubs (cup & cone) one should be careful of overtightening, not to "crank down", as that can "crush" the bearings. Old hubs "left loose" will benefit from a bit of overtightening, as per se each example. However, Mavic hubs (cartridge), that require a special tool, should be left with a little play (hub setting tempered by QR adjustment). This is garnered from the issued manual on adjustment for these hubs by the company.
In practice, this has worked.

Santa Barbara Bicycle Coalition has 3 different sites/shops. We are going to upgrade our POS system to work better with our Quickbooks online in order to make life easier and more accurate for all!
Do you have experience with how the following POS systems interface with Quickbooks? Please share your opinion and experience with support !!
- Primaseller
- Shopkeep
- Lightspeed
Thank you!! Ellen -- Ellen Willis-Conger Associate Director Santa Barbara Bicycle Coalition p: 805.845.8955 w: sbbike.org e: ellen@sbbike.org

I will ask a few questions and I am seeking if you have tests to prove your answers.
Does a quick release lever change the adjustment of a hub? Yes or No is not important, how do you test to verify your answer is important. How can this test be used to reduce service time to 1/20 the time?
What does facing do for the customers ride experience? Nothing/ Something? The following answers are guesses, beliefs, not science or engineering based: it should be done, it is done at the factory, it does not need to be done, eliminates pedal click, professional cyclist have it done. So what does it do? how does it improve a cyclist ride experience? How do you verify your answer?
How do stainless steel spokes and cables stretch once and then magically become harder and never stretch again? If they do not stretch once, then how do they get longer once? How do you verify your answer?
Do Bolts stretch? Yes or No, how do you verify your answer?
How does a chain that can stretch at 900 Kg or 2000 pounds of force get stretched on a bike frame that can only support a 160 Kg or 350 lbs cyclist. How can a 45 Kg or 100 pound cyclist put 900 Kg or 2000 Lbs of force into a chain to stretch it? Without destroying their knees? How do you verify your answer? Which leads to the question, How does one type of shift lever make a chain function twice as long as another type. How do you verify your answer?
Why do mechanics tighten and loosen spokes? When a cyclist uses a wheel spokes get looser. Spokes only need to be tightened to round, dish, tension, and true a wheel. How can finite element analysis and computational fluid dynamics help a mechanic work 36 times more efficiently?
How can understanding the Sphere Stacking Equation improve the hydraulic systems on a bicycle? (Both hydraulic braking and suspension systems) and make cycling safer.
How can a mechanic use a bench as a tool to reduce service time 25%
Would it help your school, your students, bicycle businesses and cyclist; if your curriculum included verifiable testing processes, efficient practices to reduce procedure time 25% to 50%, service sale language to help cyclist understand what a procedure does to improve their cycling experience to improve sales?
If any of this or all of this is new to you and you would like to improve your training, feel free to reach out and start a conversation telephone only. 773 -490 -0683 Christopher O. Wallace . I am located in Chicago Illinois.
PS Yes I have re-invented the wheel three different ways, I am looking to improve the cycling industry and I feel schools are the best way to do that! I look forward to hearing from you.
Sincerely Christopher O, Wallace

End of Thethinktank Digest, Vol 149, Issue 2
It has been brought to my attention that many of you do not like Trumps stance on science. Where his opinion is more valid than Testable, peer reviewed, repeatable science At the same time when opinions about the bicycle are faced with testable, peer reviewed, repeatable science, the science is questioned by members of this list.
Your opinion matters, it is called a hypothesis. Science proves or disproves hypothesis. Once a hypothesis is turned into a test and proved or disproved, then those with descending opinions peer review the results, to confirm or deny the results. If they are not happy they should test their own hypothesis's and have them peer reviewed. An opinion on the matter is called a guess.
I am told your guesses, your opinions, are to be honored and respected more than science based testing. For that I apologize.
Raise a glass to you.
Christopher O Wallace
