A silly "Dumb Trainer" question...
 

So, I have a Cycleops Pro Fluid 2 with the lever type mechanism (not the new twist lock or whatever they call the fandangled thing). I had it for 3 years, but never used it because who needs a trainer in Hawaii (got it on the cheap). Now I'm in WA State.

Anyways, I am running it with a Schwalbe Blue Trainer Tire at 115 psi, but think i had the flywheel pressed too much against the tire causing an excess of resistance.

To obtain an optimal feel and resistance, what am I looking for as far as locking the flywheel? I think I may have it set up too loose right now, but compared to what it was, it s a lot easier to maintain a cadence.

Tighten the flywheel drum to your trainer tire untill you can grab the wheel and give it a good pull up and jerk it down without the tire slipping against the drum.

I adjust the tension so that it is just tight enough so that it doesn't slip during normal training efforts: IE not trying to make it slip from a dead start kind of thing.

I like it tight enough so I can stand and sprint without any slippage.

When I calibrated my smart trainer, I ended up tightening it against the wheel way more than I thought I would ever need to.

I'd say, if you're using a trainer dedicated tire, tightening a bit more than where you think it should be, probably won't hurt.

For me, it was a "trial and error" type thing. Get to where the tire starts to flatten against the roller, ride the bike, and if it slips on hard effort, get back off, give the knob a half turn, and try again until you are satisfied that it won't slip on hard efforts. Then, remember how many turns you made, (when you take the bike out of trainer) and how much PSI you used in the rear tire. That helped me get it right just about every time I put the bike in the trainer for a session. Hope this helps.
Cheers
