Hey all,

My rear wheel feels like it's dragging. I've had my 7? Motobecane Mirage for over a year and know the feel of the bike very well. My bike usually feels pretty agile and quick, but it's feeling sluggish, as though I'm riding in soft gravel.

Of course, it *might* be the BB, but wanted to check in here.

I had a problem with a loose derailleur the other day and my wheel was dragging heavily on my left chain stay. I tightened it up, but prior to having done that I'd tightened my axle, a pinhead, maybe too much, if that's possible.

Also, I changed my tyres from racing slicks to Panaracer Pasela's, and this problem started shortly after that. And it's started getting really hot in NYC and maybe the asphalt softer, or dragging? Those two things are about when this problem started.

I wanted to know if anyone has ideas here -

. Should I loosen my BB cone to begin with?
. Should I loosen cones on rear wheel?
. Any ideas that might help?

Please don't tell me to harden up either. I'm looking for constructive advice.
