Seriously amazing! Very jealous of the technical capabilities of concept64 and the other posters in here in the Tuning / DIY Parts area of this forum.

thank you very much it is very cool
but the more I cared for and so effective products and hopefully I test wheel (www.rouesartisanales.com) is positive.
I eagerly await this comment ....

Here's the wheel here Av Concept64 discovered or re discovered the video of the execution of hubs Av

And also the contrent am an expert by Adrien Gontier from home rar
HYPERLINK " http://www.rouesartisanales.com / " http://www.rouesartisanales.com /

So I'm happy with my hub, it remains a protopype and is a good start but much work remains to finalize the hubs and make it a quality product that is more than ready to specifications imposed.

Objective''was to make a reliable product and aesthetic''

Good evening,

Here is an account with the sending of the wheel.

1. During assembly, the first item that caught my attention is negative: it is the location on which the rays. Indeed rays headed straight have a conical head ( http://www.seetool.be/media/image/3966_imagefield01.jpg ), it is necessary that the insert in the aluminum hub is also pierced with conical shape so that distribute the force caused by tension over a larger surface (reduced stress).

2. I made statements regarding the rigidity of the wheel from 500N of tension (as it is difficult to accurately measure the voltage) and up to 1050N. The curve is linear, the wheel constantly 38N/mm rigidity to the point where the load is applied, and a distortion of 0.6 to 0.67mm at 180 ° from the load. This proves that the body itself is sturdy and there is logically no weaknesses at this level.

3. From a low voltage (pre-500N), the bearing is too loose in its housing. It can easily move up and down which is bad for the life of the product that make some other noise to use. We have already encountered this kind of phenomenon on the hub Extralite SX lightweight 45g, all of aluminum with the spoke tension, the aluminum deforms and turnover is more properly inserted into the slot. I tend to think that your aluminum insert should have another form for largest share of the aluminum part deforms less, and the other bearing is in complete contact with the insert, not only by 5 or 6 contact point.

4. With an insert more massive, the hub will necessarily weight. I think you can compensate by reducing the thickness of the carbon where there are fewer constraints (center). In the center, the stresses are compression type since the two flanges of the hub off with a side component of each side, the center is overwhelmed with stress.

5. In the end, I reduced the voltage-rays so that the deformation is less important.

6. The cap system works well, there is almost no difference in rolling resistance between the load position and the position quick close.

7. The smallness of the bearings is, in my view, a weak point, as the smallness of the axis.

Hoping that these few lines help you.

8. My colleague Matthew contacted you because it has a framework Addict broken and he would repair. Can you handle the application?

Regards.
Adrien Gontier.
Here is the front wheel Concept64!

Overall I'm pretty happy with my hub!
Indeed, it is still a prototype so it's a good start.
But I still have much work to finalize and make a quality product that is more than ready specifications imposed.
