Wheel rubbing

I should have also mentioned ... the gap between the wheel
and the frame is not equal on each side. It is rubbing on
one side but a nice gap on the other side (that's what made
me think perhaps it was seeded evenly).

then put it back on (thinking it was not seeded right).
That helped just a little bit (so that it wasn't rubbing
so bad). I thought perhaps the skewer needed to be
replaced but tried that and it didn't seem to help much
either. What should I be looking for or trying? What could
the problem be? This is the first time I've noticed this
behavior and I ride the bike a lot.

Any and all help would be most appreciated.

It can only be that either the wheel is not dished or the
frameset rear triangle/dropouts are not straight.

Or, that your adjustment screws on your dropouts (if you
have them - some do, some don't) aren't properly adjusted.
Is this a general trend of the wheel, being off to the left
side, or is there a wobble in the rim? Do you have dropout
adjustment screws? Did this start happening suddenly, and
has the bike been hit or crashed lately? Tell us more.

I only noticed the rubbing (and the sound it caused)
recently. Their is a small wobble in the rim. Not sure about
dropout adjustment screws ... I'm fairly ignorant to the
bike (I've been riding for a while but can only do the
basics - change a tire, chain, handlebar tape). How can I
determine if I have dropout adjustment screws?

I just looked at a picture of a Trek 5200 on the Trek
website, and it looks like it has vertical dropouts, just
like every other recent Trek I've seen. You won't find any
adjustment screws.

Does the rubbing only occur when the wobble passes by the
chainstay, or is it constant? If after having your LBS re-
true the wheel it still rubs, something has clearly happened
to either the wheel or the frame.

Have you had the wheel serviced recently, like having the
hub bearings cleaned and repacked? It's highly unlikely,
but the shop could have put the axle spacers back in the
wrong place.

Another thing to look for would be damage to the frame.
Perhaps one of the bonded joints on either end of one of the
chainstays or seatstays has failed. This could cause things
to shift. One quick way to check frame alignment would be to
mount another wheel. Borrow one from a friend, or have your
LBS do it. If another wheel is centered you know the problem
is with your wheel.

The rubbing is not constant ... but when I put the back tire
in the tire starts in the middle (where I expect it). After
just a short ride it is once again closer on one side (non-
chain side). The wheel needed to be trued ... so I just took
the bike to the LBS and will have them retrue the wheel and
look into the rubbing issue too. I wanted to see if this was
something I could do (cause the shop's turnaround time is
almost a week - luckily I have another bike to ride).

Thanks!

This is from the wheel moving in the dropout because it
isn't being held tight enough. Force from the right (drive)
side pulls the wheel forward on that side and it 'pivots'
around the left dropout to the left and the tire starts
rubbing on the chainstay.

Tighten the wheel more. Maybe a better quick release skewer
will have stronger parts that will give more bite. When you
go pick up the bike, talk to them about this.

I did indeed try another skewer ... and I also tried
tightening the wheel tigher ... that may have helped ... but
very very slightly.

If the axle isn't perfectly centered (or if washers/spacers
are missing or mis-sized), you can have a little too much
axle sticking out past the nuts on the end. Then when the
wheel is put into the frame, and the quick release clamped,
you won't get a strong grip on the frame since the quick
release is pressing the axle end, not the frame. When the
axle is in the frame, the ends should be recessed slightly
(from the outer edge of the frame) on both sides. Getting
this right can be tricky, you have to count the number of
threads protruding past the nut on both sides

I have a similar problem on my Cannondale. Not sure what
material your dropout is made from (I doubt it's carbon, I'm
guessing some kind of metal insert). On the aluminum
Cannondale, the dropout had a depression worn into it on the
drive side from the force of the axle being pulled toward
the front of the bike by pedaling.

This causes the axle to move farther forward (not down in
the slot, but forward into the frame parallel to the ground)
on the drive side, which causes the wheel to be closer to
the left chainstay at the bottom bracket, even on a
perfectly true and dished wheel. It's not so bad yet that
the tire rubs like yours, but it might be something to look
at on your bike. At some point I intend to file away a
little of the dropout on the non-drive side to match the
missing bit on the drive side, as soon as I have the time
and gather up the courage to take a file to my frame.

From your description it sounds like you might have a broken
axle. I have twice experienced exactly the same symptoms you
describe, and both times it was due to a broken axle. I only
weight about 135lbs, so you don't have to be a heavy weight
or hit a deadly pot hole in order to break an axle. Don't
delay, your skewer may be all that's holding it together...
