Aluminum versus PVC rollers(3 posts)

Aluminum versus PVC rollersGMS

It is clear that more expensive rollers use alunimum, but I have never heard what the specific disadvantages of PVC rollers are. Can anyone compare the two?

If PVC works fine, I get to wondering whether or not I could build my own... Three pipes, a frame, and some belts. They probably wouldn't be precise enough, for one reason or another. Has anyone tried?

The trouble with regualr PVC water pipe is that it can sag and flex with the weight of the rider. Note that the Performance PVC rollers are described as "lathe turned" which suggests that they needed some finishing from the starting tubing/pipe. Perhaps if you got some "schedule 80" PVC you'd avoid the flex problem. I don't know how round PVC pipes really are. Yes, people have built their own rollers, but it is not a real common practice - you're bound to spend several hours and probably $50 in parts (roller belt alone is $15 or so), so you save maybe $100 tops and have a kludge when you're done. Go for it!

PVC rollers tend to be louder and run a bit rougher than the aluminum ones. You often get what you pay for.
