Heavy Wheels = Fast Wheels

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Heavy Wheels = Fast Wheels

I don't know why everyone here wastes thousands of dollars on senselessly light wheels. Heavy wheels are much faster than light wheels because once they spin up, they tend to stay at that speed more. You crazy wheel weight weenies need to start saving your money. Plus, imagine how stiff and aero a heavy wheel can be. Just remember, lighter isn't better.

I totally agree. I actually attach lead fishing weights to my spokes and try to buy the heaviest tires and tubes possible to get the mot rolling weight. its good to see Im not the only one that believes heavier is better.

I make my wheels out of solid uranium. People say I have a glowing personality.

I would buy a pair but that type of weight is pretty pricey. I think Im better off just filling my tubes with molasses to 110 psi. then attaching my fishing weights.

I can't afford uranium wheels so I have some stupid aluminum rims. I tried lead wheels but they were not laterally stiff while remaining vertically compliant. They dented alot too.

One time I put my steel car wheels on my bike with a custom fork and stretched rear drop outs and man it took a while to get rolling but once I did I got up to like 88 MPH into the wind on a 10% grade due to the massive momentum from the 60lb wheels and then I saw some fireworks after it got really cold and I ended up crashing into a pine tree in the year 1955.

umm the fastest wheelie mobile ever built? it needs more lead on the front wheel. and the 48" wheel in the back needs bigger uranium weights attached to it

You need the ultimate in rotational mass.....wheels made up of Quantum Singularities. Just don't get too close or you'll get sucked into their gravity well. On the flip side, those wheelsuckers will certainly get a surprise.

Yes, and by using the same principle, heavy riders are going to be much faster than all those lightweights littering the pro circuit.

On the serious, how heavy were the wheels on the bike used to set the 1 hour record?

due to the fact that the momentum carries the inertia over, the heavier they make the wheels for the hour the better. after they get them spinning they could probably set the two hour record

The science behind this perplexes me. The main force opposing movement at high speeds would be air resistance, so why would it be easier to maintain speed with heavier wheels? Certainly, air resistance slows down heavier wheels less, but you would need to put more torque into bringing the wheels back up to speed

I can see that if we have two bikes, one with light wheels and another with heavier wheels, and if both bikes are traveling at the same speed and both riders stop pedaling, then the one with heavier wheels would slow down less quickly, since it has more linear and angular momentum. But if the riders try to maintain speed, the moment of inertia of the wheel would be irrelevant, right?
