My only bike schwag purchase this year (Yeah the Big Dummy was a gift, still unridable and it's really not a road bike) for 20 bucks this year. The belt finally arrived yesterday but I found out that the drums were not so smooth once I rode the bike on them. This is an ancient Kreitler roller made by the man himself before he passed on and has poly drums. So not only it mimics the road but a very knobbly road.

I put the worse drum in the back and I can still ride it. Since areas near the edges are still smooth. I am forced to ride in an area about 8 inches wide or less if I do not want the pave feel. Oh boy my abs hurt trying to stay on that narrow a patch.

I know the solution is to get me some drums, but is there a way to resurrect these poly drums. Turn them on lathe? Wrap them on inner tube (for a car)? Paint them with epoxy. The warpness is subtle but get's amplified at speed. Bearings and axles seem okay still.

I guess this is the never released Kreitler Pave model

PS: If anybody has some drums they would like to get rid of PM me. And yeah I would even take hotdog widths at this point

No suggestions, sorry.

I have the poly Kreitlers too, but they're smooth. I didn't know they could get out of whack.

Okay, I do have one idea - look around for guys that have motorpacing mopeds/motos. They usually use one roller for that. See what they did with the other ones.

i have a plastic set too that belong to my brother. they also went out of round, i thing from the heat of being in the trunk of the car on a hot day.

i have no idea how to fix them and kreitler wants a lot for a new set drums and haven't seen anything on ebay. i know the lathe won't work to make the plastic one round, they are too soft and thin to be reshaped and hold shape. i thought about finding a steel or aluminum pipe or tube that would fit over the plastic roller but haven't researched it too far yet

Thanks and thanks about the heat warning. I may just settle for the cheaper tacx or try to score one from Ebay. CDR what do you mean when you say mopeds?

Put the warped roller at the end. While riding, have a friend kneel down at the roller, and brace a cutting tool up against the roller to shave off the high spots. A human powered lathe !
