My old Cycleops Mag trainer didn't have enough resistance, was loud and didn't clamp the bike very securely.
So, I sold it and took my friend's suggestion to get a Kurt Kinetic Road Machine and I used it for the first time today. I never really understood what was meant by Fluid trainers having a more realistic feel, but now I do. I think it will make riding inside more fun. It is like the thing has a brain and knows when you need more (or less) resistance. The resistance potential (1600 W) is huge.
Buying a fluid trainer was the best purchase I have made since ???
I was a little surprised that it is not much quieter than my Mag, but it is better.
If you have a Mag or Wind trainer, you won't regret moving up a step to a Fluid. It was so worth the money.
