That when I am in the granny gear that my rear disc brake rotor rubs against the pads? I noticed this possible phenomena yesterday and it doesn't seem to happen to happen in the middle or big rings...

There could be play in your freehub, and when the chainline is in middle or big, it pulls the hub away from the pads. Grab your wheel when it's in the dropouts and move it back and forth (perpendicular to actual riding direction).
Also, is your wheel in the dropouts completely straight?
That's all I got from this hack mechanic.

makes sense...either adjust it or get a friction thumbie for the front, or your rear hub could be slightly loose and it only moves under a lot of torque while climbing. Most likely it rubs all the time but you only notice it while busting ass up a steep climb. What brakes are you using? Originally Posted by brettf

Juicy Sevens 180mm rotors with a bolt on rear. I was pretty sure and brettf was there with me when I tightened the wheel after flatting last Thursday. I will check that tonight and it may also be the derailleur, which needs some serious adjustment. Originally Posted by Choke Slam

Maybe it rubs all the time and it's just louder in the granny because you're going slower?

that is what I initially thought. But then I took the brake off and swapped the pads around. I put it back in the middle ring and it seems to spin freely, but then after riding a little while, I put it back in the granny gear for a longish climb and it started rubbing again. This was also apparent from just spinning the wheel too... Originally Posted by kidwoo

Did you try to re-center the juicys (know what I'm talkin' about?) while in granny gear? Originally Posted by Rontele

Try to duplicate it in a stand and see what's up. I'm sure you checked the seating of your axle in the dropouts...ie: tighten it with the bike on the ground so that it's definitely bottomed out in the dropouts.

I still think it is an axle issue.
Its either not in there straight or its not fully tightened.
The freehub idea is also a possibility, although, I seemed to remember that the rotor was rubbing on the inside pad when I was tinkering with it yesterday.
