## Questions & Answers

**Q: What is the weight capacity?**
A: According to the manual that came with the rollers, 150kg.

**Q: Are these parabolic rollers? The description says they're parabolic, but the pictures show flat.**
A: They're flat, but the product rollers do roll easier than say a TracX parabolic.  I used a TracX and the parabolic doesn't help much.  You have to get used to riding on rollers.  I went off the rollers on TracX because of balance and the rollers didn't roll smooth as the Rock Bros Product.  Also, if you weigh over 210lbs you need to use high pressure tires (115 psi or higher) to have a smooth workout.

**Q: Where can i get the replacement rubber belt? One is stretched with 3month of use**
A: Similar belts are available from Amazon, just make sure they are round and the appropriate length.

Personally, I would take the fact that the rubber belt became useless as an indication of the quality of the product. I threw those rollers away and bought a different set.

**Q: What is the diameter of the roller?**
A: 3"
