Bike Myths We Wish Would Die

I'll go first:

1) Bike tires need to have directional treads to prevent hydroplaning.

2) When building a wheel, the greater the spoke tension, the stronger and stiffer the wheel.

3) A stiffer rim will give you a stiffer wheel.

4) Bicycle wheels need to be balanced to within precise limits, less than the weight of valves.

5) Rotational mass will slow you down much more than static mass.

6) Aluminum doesn't corrode.

7) Carbon fiber is more prone to catastrophic failure than other materials.

16) Always observe your thighs vis-à-vis your bike's top tube when riding, to make sure you are not hitting said top tube with the aforementioned thighs.
17) Physical reality and engineering principles should NEVER be invoked to challenge "feelings" and "belief."

please explain why bikes don't hydroplane
Could you really not look this up yourself? Here's the formula: Vp = 10.2 sqrt(P) Vp is hydroplaning speed in mph, and P is pressure in psi. So for a bike tire at 100 psi, hydroplaning starts at 102 mph. At 49 psi, hydroplaning starts at 71.4 mph. Amazing what you can learn when you actually choose to.
