Some trainers come with a polyurethane roller not metal. I think that would be a lot better then the metal one. Has anyone used a polyurethane roller? And if so are they good or just the same as metal when it comes to wear and tear, and slippage ?
I haven't had a poly roller for long, only a season but I've never had any issues with slippage, though I always use a trainer tire on it.
Wear and tear I can't note any difference after a season of use other than some dirt and marks from my tire. Nothing deeper than surface dirt. Hope it helps!
I've used Elite and Tacx trainers. The Elite had an elastomer roller and the Tacx a metal one.
The elastomer one is quiet and I do experience slippage on the metal one. However, they apply pressure to the roller differently. The Elite uses suspended weight of rider and bike - whilst the Tacx uses an adjustable mount rising up to the rear tire. On my Tacx, the small amount of slippage is only for a short period as the tire & me warms up - maybe a few minutes. On the elastomer roller - no slippage, less heat build up too. I could adjust the slippage out - by applying more pressure to the rear - but it is such a VERY small amount - which happens only on out of saddle efforts (calibrating the smart turbo) and is gone after a minute.
Still using the same tyre on both. And have used the tyre for a good few years now.
