My hed3 rear wheel had problems below
1. bent cassette body(when it rolls the cassette shakes)
2. hurt bearing guide(when it rolls it makes an unusual sound and rough feeling)
3. curved rim
So I sent it to Hed company and it was returned to me several days ago.
They fixed 3 but '1 and 2' were not.
This is the e mail from Hed company.
[font=Arial]The cassette on the H3 and Disc will shake when the wheel is coasting. It does this because of the way we true the wheels. There is a small shim between the cassette body and the hub shell - this shim makes the wheel true (so the rim does not curve). The cassette only shakes when the wheel is coasting, not when it is being pedaled. [/font]
[font=Arial]Your mechanic should be able to fix the bearing guide by adjusting the axle. If you need another bearing we can send one. [/font]
[font=Arial]DO NOT REMOVE THE CASSETTE BODY! It will make your rim curve if you do this. [/font]
[font=Arial]I(and my mechanic) don't understand the explination about the cassette's shaking.[/font]
[font=Arial](My mechanic said it's because the axle part is bent)[/font]
[font=Arial]and when the rear wheel rolls on my hand I can feel rough momently.[/font]
[font=Arial]It rolls quite smoother than before but still has that problem[/font]
[font=Arial]what can I do?[/font]
[font=Arial]I need your advice.[/font]
