ホイールの話 その1 重量について

Wheel story 1: weight

Wheel story 1: weight

This time I would like to talk about the weight of wheels .
Of course, it goes without saying that lightness is justice.

As an example from my own experience, in 1995 I put PVM mag wheels on my ZZR1100D1.
The effects are as follows:
1. Better acceleration, 2. Better deceleration, 3. Easier leaning and turning, 4. Better appearance.
In particular, with regards to ③, my sleep has changed from being a steady one to being a smooth one.
I compared it to a friend who was riding the same bike at the time, and it was a completely different experience.

Recent OEM wheels, especially the larger, higher-end models, have become lighter in terms of apparent weight.
For example, the ZX-10R is equipped with Marchesini forged aluminum wheels on higher grade models or as an original option.
The weight difference between OEM and Marchesini wheels is only a few hundred grams.
But the ride quality is noticeably different. The reason for this is that the parts are made lighter.
While genuine products make their weight lighter in the hub area, aftermarket products including Marchesini make their weight lighter in other areas, especially the rims.
So why is it that genuine parts do not/cannot be made lighter with rims? It's because the manufacturing methods are different.
*Materials (magnesium, aluminum, etc.) will be explained separately.
There are exceptions, but generally speaking, genuine parts are cast and aftermarket parts are forged.
Castings are inexpensive to manufacture but have low strength, so it is necessary to ensure thickness.
Incidentally, the weight per unit volume of forged steel is heavier due to its higher density, but its strength is greater, so it is lighter for the same strength.

Imagine swinging a plastic bottle in your hand versus tying the same bottle to your upper arm and swinging it around.
The former will feel heavier, and this is the case with the genuine wheels. The aftermarket wheels will feel heavier, and this is the case with the genuine wheels.
Even if the weight is the same, the part that is farther away from the center of gravity/fulcrum will feel heavier, so the weight will be different.
The reduction in unsprung weight really pays off.
If you combine it with aftermarket high-end suspension and a lightweight swingarm for a synergistic effect, your dreams will expand.
Many people who have replaced their wheels once are so impressed with the results that they come back again.
I too have changed the wheels to aftermarket ones on my ZZR1100D1, ZZR1100D5, ZX-12RA1, and ZX-10RD.

Well, when it comes to tubeless wheels for the CT125, GANESHA is the one!
Thanks to all of you, we have become the leader in tubeless wheels for the CT125 and have gained a great reputation.
Now, GANESHA has released a new line of tubeless wheels under the RIN brand!
This RIN is approximately 200g lighter (front and rear wheels respectively) than the original wheels.
This difference in unsprung weight is quite large.
GANESHA wheels use genuine hubs, so the lightweight part is purely the rim.
As mentioned above, reducing weight with rims is extremely effective!
Furthermore, because it is tubeless, it is even lighter since there are no tubes, so we hope you will enjoy it.
