This is the single best product for trainers. It is simple, reliable, and will last for along time. Great resistance. Makes a better pedal stroke, and you have to actually try. unlike stationary trainers
I have had the new version for a year. I have had no issues. The set I had before was almost 20 years old and worked great! I love these and suggest the for warming up for any cycling event. I also train hours on them in the winter when it is just to cold out.
