I got a question about spacing of rear hubs. I'm currently on a '03 giant dh team which I think is 150mm in the rear? I have a '04 turner dhr on my way to me which I think is 135mm in the rear?

My giant came with an AC hub. I was looking at it last night and there's a spacer on each side of the hub. A bigger one on the non-drive side and a smaller one on the drive side. If I had the correct size hub for the rear would there be spacers? This might explain the horrible chain line this bike has, I always thought it was due to the giant chain guide.

Is there a way for me to measure the spacing on my current rear wheel. I want to ride my DHR as soon as it gets here and I'm trying to avoid having to build a new rear wheel right away.

1) Giant chainlines suck. It's not your guide.

2) Aren't you getting bibb's wheelset with the right sized hub?

3) The best way to get a measurement is to measure.

Without looking at your hub, there is a possibility that you have a 135mm hub with spacers to fit your frame?

Bring it over. We'll just measure it. With this weather, I'll be home drinking beer and chucking bottles at god anyway.

He backed out on the wheelset last minute. He said the rear was not rideable. The frame should be on it's way to me this week. You gonna be around tonight?

The 2002-2004 Giant DH frames have a 135mm wide rear wheel with a non cenetered dish. Anotherwords, you will need to adjust the dish for any other frame.

The only Giant DH frames with a 150mm wide are the 2005 frames and some one-off "team" frames. Don't be confused, your team frame is the same as the comp frame and completely different than the real team frame. Eitherway, you have a 135mm. Measure it with a ruler

what is dish and how do you adjust it?

what is dish and how do you adjust it?

Dish refers to the offset of the rim from the center of the hub. Since you have to make room for the freehub body on the drive side, the spokes on that side are shorter. Same applies for disc brake hubs on a front wheel. When you hold a hub in your hand, what looks like the center of the hub body, is not really what gets centered when it's in the rim. Sounds like giant just did something wierd with a standard hub.

A dishing tool lets you compare the two sides of the hub when you're building a wheel, relative to the rim position. To re-dish your wheel you need a truing stand, preferably a dishing tool, and a spoke wrench. In other words, take your wheel to olympic and ask for Sam or John. And measure your hub dammit!! Based on what chriskring said, you may not have build another wheel.

You can adjust dish some, but depending on how far you have to move you may need new spokes to keep the wheel correct. To dish you loosen one side and tighten the other in even increments. If you go too far one sides spokes will be too deep in the nipple and the other too shallow. THis will make your wheel weaker, and also tend to loosen more. 9or so my experience has been)

Like KidWoo said, take it to a shop. Its easy to start to mess a good wheel up.

the frame is here and i'm getting things ready to put it together.
*bibs if you read this that was the worst packing job I have ever seen and your PMs are full*

so I measured the the AC hub I currently have on my Giant. The rear end is 135 mm from the inside of the frame to the inside of the frame, and I'm guessing that must be how it's measured. The rear hub currently has a 23mm spacer that is on the non-drive side. Does this mean I have a 112mm hub. Is that correct? Is there supposed to be a need for a spacer in there?

 

[ioscope]

DHR is definitely 135
Wide hub spacing actually makes sense!

You should be able to install the wheel with the spacer in the turner frame. They are both 135mm x 12mm. The only difference is about 1/2" of dish. If you don't feel comfortable redishing the wheel yourself, any decent shop should be able to do it for ~$15.

Have fun with that bike. Bibs let my gf ride that bike for a day and it convinced her to buy one of her own.

Ok, so you are saying that spacer is supposed to be part of the setup?
