Kind of unchartered waters when it comes to bicycle trainers, so I'd like to pick BFs brains for best bang for buck to a bicycle trainer that is proven from experience to be durable & simple with basic functionality to be used on the rear of a trek hybrid bicycle.

I often read the term "trainer" & "rollers" be tossed around. I'm assuming they are both of the same terms? Or does "rollers" =13pxstrictly mean to be used with an existing wheel affixed to the bicycle? I would prefer to mount the bicycle as a whole in/onto the *trainer* & set the tension as needed, but that doesn't mean I wouldn't consider dismounting the wheel, just keep in mind that I will require the shifting of gears to "simulate" as much outdoor feel as possible to not become bored when using it during the unfortunate indoor cycling days.
I dont use apps so Zwift & Kickr etc etc is not a want as all the gadgets & meters are already equipped on the bicycle.
Just a simple & basic setup.
