Central Indiana wheel builders

That flex could also be your frame flexing a little bit.

I don't think that's the problem. The derailleur is a direct mount on the chainstay, so flexing in the front triangle and suspension movement shouldn't have an effect on the distance between the tire and the derailleur. And I certainly hope my rear triangle isn't flexing that much on it's own...

It's certainly not an easy or a fast job, especially for a first timer, but it isn't rocket science, either. If you're at all mechanically inclined, it's totally doable. When I got started, I figured that even if I messed up and had to take them to a shop to be trued and tensioned, that'd be cheaper than paying for a build.

As another newbie wheelbuilder, I'd just say to take your time and double, triple, or quadruple check your lacing. I found it helpful to do a couple of sessions of truing, too, so that I didn't rush or get frustrated. I probably put about 10 hours into building my first set. (While I'm at it, I'll also raise my hand and admit that I got slowed down a bit because I kept turning the nipples the wrong way. Yeah, figuring that out sucked.)

Have fun building 'em!

Luckily Ive gotten that nailed down as I true wheels all the time.
Also Ill have to look into a tension gauge as I thought they were around 120-150 retail.

Got these wheels finished the other day, and they turned out pretty nice... aside from the flex in the rear wheel that I wasn't expecting to get. Under heavy load I'm getting 2-3mm of distortion in the wheel. Spoke tension on the drive side are all at the mfg's recommended max so I know that's not the issue.


I can't actually "feel" the flex (at least on flat pavement), I only noticed it because I had a bigger tire on the back that rubbed the front derailleur when I really mash it, so I guess I'll have to see how they are on the trail when things dry up.


Thanks again for the input everyone!

What setup are your running ? I have the same issue but my wheels are only around 1200-1300g and at a lower spoke tension than most rims on the market to prevent cracking.

Chris at Motion in Fishers built my 650b Flows. He did an outstanding job. I'm thoroughly pleased.  $35 a wheel.

As long as your spokes are not going slack, stiffness of a wheel does not increase with increased spoke tension.  With regards to stiffness, it is entirely a function of spoke thickness, assuming all other things equal.
 
It seems to be a common misconception that if you crank up the spoke tension on a wheel, it will get stiffer.

They're Pacenti TL28 29er rims on Hope Pro2 EVO's laced with Sapim Race spokes. They came in around 1800g for the set so they're not exactly feather weight. I dropped my rear tire pressure down a little and haven't noticed any rubbing out on the trails the last two nights. I'll just have to be careful with pressure and tire choice I guess.


Aside from that though I'm absolutely amazed at the difference losing two pounds of wheel makes.
