What is the advandage of alloy wheel over the spokes wheel for two wheelers?

Question

any technical reason behind it? is milage difference avail? pls suggest me.

Answer 1

Spoked wheels usually have a tube, cast wheels are usually tubeless, even though they have a sealant that can go over the ends of the spoke nipples (where the rim rubber usually goes, to prevent the spoke nipples from rubbing a hole in the inner tube) that will let you run tubeless tires.
However, if you bend a rim, instead of just buying a new rim and relacing it to the hub, you'll have to replace the entire wheel.
But, a cast wheel's spokes won't ever loosen, as they're cast solid.

Ok you young pups, when I started riding ALL bikes had spokes. I also remember when the hot thing was to replace your spoke wheels with aftermarket Lester or Morris mags. Yes, one piece wheels are made to run tubeless tires but the advantage of tubeless isn't in fixing them, it's how they hold air. Tubeless tires have a soft rubber interior layer that helps seal around a foreign object like a nail. Tubeless tires can have a nail stuck in them and never lose a bit of air. Run over a nail with a tube tire and air will leak around the object and when enough air leaks out, the rest rushes out around every spoke, valve stem hole, tire beads, everywhere. In addition, more often than not, when a tube is pierced, the tube tears into a big rip and the air rushes out before you even know what's happened. It doesn't matter whether the wheel is a one piece or not, a tube type tire and inner tube will have you sliding down the highway instantly. The rear one piece wheel on the back of my Kawasaki has what's called safety beads, two ridges that hold the tire's bead against the wheel. Nothing new, cars used them in the 70s. What they do is keep the tire on the rim even if it deflates almost instantly when you run over something like a big piece of glass in the middle of the night and put a 1 inch gash in a nearly new tire. Yeah, that happened to me. When it comes to flat tires causing bike wrecks, it's nearly always the rear tire and not the front. I won't go into the steering geometry changes that take place when the rear tire's beads break loose and let the wheel wallow around 3-4 inches from side to side, but take my word for it, it ain't good.

I can't remember who, but just recently some manufacturer has produced a bike with tubeless traditional looking spoked wheels. Might be Velo? In the late '70s Honda had the Comstar wheel, a tubless rim with 5 or so pressed steel "spokes" riveted to the hub and rim. It was meant as something that had the good riding qualities of spoked wheels (they flex and smooth out bumps) but the ability to used tubeless tires. So there you have it.

Answer 3

The advantage of the alloy wheels on cycles is the use of tubeless tires. The tubeless tires can be plugged when they have a flat, so you can still ride on. The spoked wheels usually have tube type tires that have to be broken down and have the tube patched.

Answer 4

It's actually more important to balance motorcycle wheels than four wheelers. The balance weights on alloys tend to be hidden which is why I suspect you think they weren't balanced.

Answer 5

spoke wheels are hard to keep round & true if used hard. old ones have to be "tuned" every year or so to keep them running within 1/32 this is more art than science & usually costs $100 & up for each wheel because of the time & skill involved.

Answer 6

K5 and strech are correct. Just one more note about spoked wheels. The spokes do need to be adjusted (tightened ) periodically to keep the wheel true. (Balanced and "straight")
This adds an additional expense.

Answer 7

alloys are lighter.....and add less wind resistance..less resistance...better millage....less effort....
