Not a bad indoor trainer, this is my 2nd (or is it 3rd?) Elite. The roller always wears like that - amazing what hot rubber will do if you try hard enough. This is probably 8 years old, but it has shared the load with an even older - 13 years or so - Elite. The tyres of course wear even faster.
It's a magnetic resisitance unit. Not the best feel but useful, especially when you run an iBike or similar power meter.
