Title: Buckled ACS Z-Rim
Post by: Kaner on December 04, 2009, 02:13 PM
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 (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 :daumenhoch:

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  :daumenhoch:

After all the rims are only plastic...

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.

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   :idiot2:  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.
