Buckled ACS Z-Rim

[Kaner]

I recently bought these and 1 of them is badly buckled   

This photo is taken when the rim is sat flat on a level table, the gap shows the deflection   






Will the buckle come out when it is built up or do I need to try and straighten it first?

How the heck would I do straighten it too?   

Any ideas anyone? 

Cheers Ben

Ben, I sold u this!
When you build it up it will come straight out, if this was steel or ally then you would have a problem.  I can recommend this book http://www.amazon.co.uk/Building-Bicycle-Wheels-Robert-Wright/dp/0890371067/ref=sr_1_2?ie=UTF8&s=books&qid=12 BITD I used to build everyones wheels after getting this book when I was 13.  Try and practise on an old or fooked wheel. Any probs PM me.

As Toys said, that will come straight out if built properly

Put them in the freezer 

(how many times have we heard that in the past....)

I've built up a few Z's and most of them have been like that if not worse, the spoke tension will true them up, no problem  

After all the rims are only plastic...

[toys19]

I've seen plenty of brand new rims that were straight when they arrived, by the time some muppet laced them up they werent....

ben  defoo when they are laced up they will come true mate  100%

Wicked news!  Big smiles all round.   

They are currently in a big bucket of dye . . . getting a tan!

AS everyone has said that will come out as soon as they're laced.

Thre's loads of different methods to lacing a wheel though. A lot of people like the Sheldon Brown way of doing it. I think that Stidds 'How To' follows this route.  I used this method a lot until I learned the Shraner way of building a wheel.  This is so much easier to do than the Sheldon way.

I have a wheel to build tomorrow at work so I'll do a how to then for everyone.

I was just wondering as it's not my era and this problem seems to be solved.

Are ACS Z rims good? I mean are they strong and light? I've always wondered about it you see and why they didn't take off. They are very cool, I just wondered.

[bigsman]

Well they're light....! 

[Voodoocars]

I wouldnt mind a set on my new school.... You wont see many of those at the skatepark.

[Kaner]

Not quite what I was looking for . . .



WTF have I done wrong?   

4 sachets of black dye and 1kg salt included, lots of prep too. 

I dont want brown a rim!   

[Zippy]

I bet the SE fans have just fainted seeing hose pics. 

[Kaner]

Fook it, off to pub!

I dont want brown a rim!   

Anal bleaching?

[rollin72]

how did you prep the rims and what dye did you use?

[trasher]

hello ben
these where the exact same colour as yours mate ,,,gave them a bleach before dying

then one sachet of rit dye ,,,runs rings around dylon ,,,,in a metal dustbin ,with a camping stove underneath ,to keep the heat constant ,,about half an hour later ,,,hey presto 

sorry for the shitty phone picture 

[Kaner]

how did you prep the rims and what dye did you use?

I used CIF to clean them and then 400 grit followed with 600 grit paper and a good wash after.

The rims are now in a bucket of bleach and have gone back to blue     I suppose its better then brown though?!

I went and got some RIT dye too, so I think I will try it all again tomorrow.
