Feeling resistance when pedalling...! (Solved)

Hello, brand new poster here. Sorry if it break forum etiquette by asking a question before introducing oneself.

Basically, I've got a Trek 4000 MTB and have lately being feeling real resistance when riding. I thought it might be the bottom bracket, but I've just had that replaced (as well as a general service) and while no problems were found, the original problem hasn't been addressed either, so I was probably wrong in my original estimation.

After some trial and error riding, I have worked out the following:

- it's almost definitely not the brakes rubbing (obvious, I know), although that's how I would describe the sensation. It's like riding with the brakes on.

- it does not happen when I'm free wheeling or riding on the flat (so the problem only really occurs when I'm riding uphill and/or standing out of the saddle).

- the wheels spin perfectly when I'm not on the bike, and when I'm checking for any resistance to the wheels turning.

- The resistance is often accompanied by a sound which is rhythmic, almost in time with the turn of the pedals.

- I've recently (say, within the past 12 months) had the left pedal handle/axle (sorry, don't know the correct term, even after checking Sheldon Brown's glossary - I refer the the stem that joins the actual pedal to the frame) replaced.

Any ideas? Any suggestions would be greatly appreciated.

SOLVED: the back wheel is rubbing against the left hand of the frame when I put pressure on the left pedal, due to snapped axle in the back wheel.

Thanks for taking the time to read anyway

Hey, thanks for posting. I have added your story to my mental database of problems and possible causes.

FWIW, I saw the same thing happen with a neighbor kid's Huffy last month. He brought the bike to me with the tire rubbing on the kickstand, and the root cause was a broken axle.
