Thanks for all the quick replies. In road cycling aerodynamics greatly affect racing. There are many ways to shave 20-30 seconds off your 40km time trial. This is normally accomplished by an aero helmet, wheels, frame, clothing, etc. However, in mountain biking aerodynamics isn't as much a...

There are tons of factors here. But I am mainly interested in seeing if there is any real life measurable advantage to decreasing inertia. Keeping everything constant (stiffness, thickness, price, etc), is there an advantage if I build up a wheel using rim A at 545 grams, rim B at 425 grams, and...

Thanks for the help. I understand that accelerating the rider is much more work than accelerating the added wheel weight, how does the decrease in rim weight translate to watts and/or time savings. Let's say I can hold 250 watts over 40km. Using this website (bikecalculator.com) a 300 gram...

In the bicycle industry, there is a lot of marketing saying that rotational weight is more important than static weight when it comes to accelerations and competition. I understand I=mr^2 but how do you compare differences. Keeping the the hub/spokes constant, how much advantage would you get...
