The wheel is a bicycle flower shape.
It is no exaggeration to say that it is a factor that has a great effect on the ride but also the riding comfort, and determines the characteristics of the motorcycle.
That's why it's important to choose the specifications you want, and this is actually difficult.

It is only weighted as a clear indicator in catalogs and blogs.
What about the durability element that users who mainly use city riding like us cannot ignore it?
You can imagine vaguely, but let's unravel those vague determinants.

Wheels as a structure

The wheels are composed of parts called "rim", "spokes", "nipples" and "hubs".
The characteristics of the wheels are determined by those interactions.

rim

The rim is located on the outer periphery of the wheel.
It is a part that attaches the character of the wheel to some extent depending on the material and shape.

Words that are often talked about in durability are "rigidity", "strength", and "accuracy".
First of all, I would like to define rigidity and strength, which are often confused.

·rigidity
An element that indicates the difficulty of deflection to the load.
How hard it is to deform within the range that returns to the original shape?

·Strength
An element that represents it hard to break.
How much load is deformed so that it does not return to its original state? Or will it be damaged?

From a durability point of view, it is an important factor, of course, the strength.
Rigid is a factor that affects the ride, but it has a deep relationship with durability.

If the rim is difficult to deform, the load on the wheels will be widely distributed.
As a result, the load on the fitting portion such as spokes, nipples, hubs, etc. can be reduced, and the durability as the entire wheel can be improved.
It can also be said that accuracy is effective for the same reason.

spoke

The metal line connecting the hub and the rim is a spoke.
The wheels maintain the strength as a structure with the tension of this spoke.

Generally, spokes include straight "plain spokes", "vated spokes" in which the middle part is thinly forged, and "aero spokes", which processes the middle part into a flat shape.

Simply, the thicker the spokes, the higher the strength, but they become heavier.
In addition, plain spokes of the same thickness from end to end have poor elasticity, and the load is concentrated on the rim and hubs, and it is likely to cause metal fatigue. (But cheap)
The thin vmed spokes and aero spokes in the middle part not only can be lighter with the load on both ends, but also provide moderate elasticity and distribute the load on the fitting part.

It is easy to say that spokes are cheap for the time being, but it is not only durable as well as upgrading but also many merits.

Hub

The central rotating body, the parts connecting the wheels and the frame are hubs.

In the context of durability, do you see the bearing first?
I often hear that bearings are good ceramics.
In fact, ceramic bearings are resistant to corrosion and wear, so it is easy to maintain a smooth rotation. (Although it is expensive)

I also want to worry about the hub body and the strength of the flange.
Occasionally, I see something that sells the lightness of rotation when turning by hand, but it is dangerous to judge it alone.
It is important to be able to actually attach it to the frame, get on and demonstrate that performance.
It is extremely difficult to reproduce the load on the wheel just by turning it by hand.

Therefore, some strength and weight are proportional.
I still want to make the wheel lighter! We recommend that you lighter the rim.
If there is a wheel of the same weight and the weight of the hub and the rim is different, the lighter rim will have a higher initial speed performance.

However, there is almost no suggestion of excessive weight reduction that damages durability.

summary

Did you get a little vague image of your wheel durability?
I wrote a blog myself, but the bicycle is really deep. 。
Actually, the story of the nipple is not troublesome.

You don't have to understand all of these.
