Bike trainers..what the?

I am in the market for a second trainer so I can set the wife up on her bike. Looking at many brands, I keep seeing plastic rollers instead of the metal at tire contact. Manufacturers "cheaping out?". I'm assuming this would be detrimental to longevity of the trainer?

BTW, only one I have ever used is a magnetic, is a fluid worth the higher investment?

I think the fluid units are quieter. Plastic roller wouldn't last long; cheap and avoid.

Link to said plastic rollers? I've never encountered one. Sounds like a horrible idea since there's lots of friction/heat in that area.

If budget, go for a used fluid on the local forums or Craigslist/Gumtree or whatever. Sometimes under $100.

The roller on mine is metal. The black bracket is plastic.
It's worked great for years.

On mine I did take a file and score the metal roller.
This eliminated any wheel slip.

CycleOps Mag Trainer (Amazon)

Oddly, the photos appear to match the CycleOps Fluid Trainer (Amazon), not the Mag Trainer where the review is.




I realize the trainers create resistance, which is transferred to the wheel, and then becomes the energy for the cyclist.

Yet, that carnage is pretty extreme. It is hard to imagine that happened with 100 miles of use.

I wonder if that was rubber rather than plastic.

Anyway, something else has to be going on. For some reason tebsion on the wheel (and friction adjustment) is sufficient to cause extreme slippage.

New tire? Hard to imagine the two were a pair. Also, why is it so off centered?

I've been using a fluid trainer for years with no problems.
