[QUOTE ]I've bought one of those Aldi Turbo Trainers for £50. So, obviously, first newbie mistake is that I used it with my regular tyres. As my road riding is probably done for the winter this is not a huge deal at the minute. I'm more concerned that the roller, which is rubbery plastic and not metal, has had a groove worn into it. Surely this is going to continue to wear down all the way through, no?[/QUOTE]
I got the same one for Xmas and having just completed my third session it’s worn right through to the metal (with a trainer tyre as initially I thought it was my bike tyre that was shredding with the friction). Conclusion I think - you get what you pay for! Back to the drawing board!
