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'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.
