Hi YouTube Hi everyone, welcome to AnimalLand
Last time I greased up the bearings on this wheel
This time
I do not do it because the front wheel is the same method as the rear wheel
I'll do it myself later
Around this front chain league
I disconnect this chain and also cut the chain
I think I will change it.
Oh yeah.
It is an elliptical chainring
It is a very odd elliptical chain ring. I do not sell now, I can not get it
I will now explain why this is not available now
And then I will show you where this movement is going when the chain is stretched
Let's zoom in a bit and let's see
Well, I will look at this chain Here is where you can see how this chain is growing
I think I actually know how this situation is if someone knows where I am addicted
I will explain a bit.
In this state Around here
Loosening this much by touching
look
It's loose, especially the most drawn part is here.
It is the most drawn here
Fit tightly here. This neighborhood is loose, but this neighborhood and so on
The new chain does not shake at this level
This is a proof that it is growing much
People who understood this movie think that I noticed that the chain shrinks a little when the blade sticks from this growing state
People who understand it can feel it by seeing it
This is because the chain stretches a little bit faster than this
Even if the sprocket stretches out There is no such thing
My teeth are almost scraped
You can compare inner with center
How to cut is different
There are many outerwear when running in the town Inner is almost not scraped
I do not need to replace the inner yet
The center is cutting a little. The outer is terrible. It is only about replacing these 2 pieces this time
This one is still 3 months after I replaced it
I have been riding for about 3 months. please look. It will only move this way
Even when turning
There is no movement of stretching or shrinking. I am addicted.
I do not move like sticking in the back of the gear blade and going out a little while ago
It will move like this when power is applied to the front. There is no such movement
New and perfect fit from the beginning
Such a place is different
like this Mostly
Sticking firmly
Well this is whether the neighborhood is growing or not
For example, in the case where the chain is stretched and the sprocket has also been scraped a lot
Even if the chain only has a new chain even when the chain ring is out of position
The sprockets are already open The chain will also be difficult to fit perfectly
Of course, it is the one who is sharpened, so it is hard to cut down to the inner side
The lifetime of the chain is shorter to some extent
The chain life or sprocket has a longer life span. It's roughly the same
After that change the chain and change the sprocket and chainring 2 or 3 times
I think that you think that it is such a cycle
Well it is such a feeling
I checked the difference between old and new chains
This is graffiti. I also extend sideways
When you change it, lateral force is applied, it will be scraped by force against the side
There is a gap here. So the horizontal direction rattles.
While running I do not actually feel this backlash.
The new one has almost no backlash
It is safe because there is no gap in the chain
OK, please look at this. What do you think It is a chain ring which I could not fashion 30years ago
Do you know something if you look closely at this form? It's a little strange shape
Actually, some people say it is a defective item
I have various people to say There is also a difference in thought, so SHIMANO was doing this well
Now I can not get this type at all
So, was not it good? I think
I think that you can demonstrate the most power around here when you row
The most power is added at this 4 o'clock, and the power weakens at 6 o'clock
Repeat this
The chain rings are the longest in these two places
Because it gets strongest around here Well the tuning range will be wider
Just this chainring is somewhat different
Here the most power is not added
I understand?
It is the structure that the distance is shortest at 2 o'clock, 3 o'clock, 4 o'clock and no force is applied to the tire
It is at 6 o'clock that the most power is added It will be the longest here
Here, the power to pull the chain is stronger
Is it weird? Do not pull on the chain here, pull the chain the most here
It is the structure
Look at the gap with this front derailleur
Start from here. I will gradually move away from the nearest place. I think I understand it.
It is three o'clock now
4 O'clock
It is closest at 6 o'clock. This is the movement
This is the bio pace. If you say why this form,
By doing this it seems that you can go through the place where power is needed
So, it is thought that it will be able to turn faster
It is a type of elliptical tuning that focused only on turning a round grouping without power.
It is quite different from recent elliptical tuning
Let's see the elliptic tuning of this time
Where power does not join first, This gap is quite wide
As you go around
It is getting a little narrower. do you understand?
It's 3 o'clock, it's getting pretty narrow here
And at 4 o'clock here is the narrowest This is going up to the highest point
I think you can see it here. It is very open.
I'm opening at 6 o'clock.
It is wide around 1 o'clock and 2 o'clock
In this case, the power becomes strongest at 4 o'clock. It is made with the design of.
In this case, the power becomes strongest at 4 o'clock. It is made with the design of.
With this screw you can change its position slightly
I leaned at 5 o'clock,
It is a type that can be adjusted slightly before 4 o'clock
I cut the chain ne
Please watch another movie on how to chain cut
When the front desk becomes free, it turns like this
I'm going around with a nice touch.
Okay, bb overhauled last year. I also exchanged the bearings
I will remove it. It is to remove it now I think that I can see it
With this you can not enter the tool. Since it does not enter, first remove the innermost chainring
Remove the outer using this tool after detaching the inner
It is so hard that I release the video camera a little
I'm going to kick the video camera You sounded amazing, right?
I feel like that. It is a weight of 30years
I think that I can not see it
I got out
Remove the crank so the inner will not come off
Let's take off the crank
Do you also remove the crank? I feel like that, but
So here is the ratchet
I was already missing out already
OK, it was out
It is cottonless.
I'm preparing, I'm going down behind now It fell to the back
I am trying to make it visible as I think that there are many people who have not seen Cottarrez.
I will put the cotterless in the inside
If you put it halfway, the screw will be broken so please put it in firmly
Then, when you get in all the way, close it.
You had better keep this down when you tighten it
If you do not hold it down here will be tightened quickly
I will do it while holding down here
15 mm
I will turn it.
I already went around. You can leave it as it is
Came off
I got out. You have a distorted shape like this
OK, there is a chain ring removed here
Indeed, this magical chainring is goodbye with this.
The smallest chainring
I can not get this. This size. I do not know whether it is again or not
I have searched but there was nothing at all Please tell me who you see
A new chainring to replace this chainring
I am thinking of attaching a type of perfect circle that is not an ellipse.
Chainring that turns into these two chainrings
I am going to put the same type as the one described in Bianchi
Since I can use it in Bianchi, I purchased it thinking to attach the same thing
OK, this time I think I will finish with this.
Those who came up with this video, interesting thumbs up, thank you.

Bye
