Hey Guys,

Recently I bought a cheap craigslisted cycleops wind bike trainer. I've only tried it out twice now. It doesn't have the adjustable legs so i'm angling downwards slightly which is not a problem. However, I've come to realize the horrors of craigslist as the rotor with the fan blades is not trued and is wobbling out and at times hitting the cup that surrounds it.

I'm no expert, although I am an engineer, but it seems that I'm at the crossroads on whether or not I should attempt to fix the darn thing or buy a magnetic one instead. Noise is not a factor for me since I have a loudish fan on to cool me off as I'm crankin it anyway. Also, should I not be tearing up my GURU frame on that trainer? Each pedal stroke - when I'm leaning into the cockpit - is causing the frame to torque from side to side. Should I be using that climbing block? Not sure if I'll be level if I do that. Even then, I tried to solve the problem by tightening down the locking mechanism for the skewers. It seem to "alleviate" the problem, but I could still notice the frame stressing like a bad rocking chair or an old wooden bed frame that creaks every time you get into it, or the wooden floor that creaks each time you step on it. It's pretty noticeable and irritating.

Should I just use my aluminum specialized (older) bike instead? Get a new trainer? Fix the trainer?

Let me know your thoughts.

*Post Script*
Just found out it might be because i'm Cranking a 50(front)/15~21 (rear) combo while being on the trainer. Should I be in my 34 front and maybe 15~21 rear? Will that cause me to focus on my pedal stroke, though I'd only get an aerobic workout, and not stress the frame?

*note - i haven't tried the above yet... I will tomorrow
