As you've no doubt figured out (assuming you've been reading my blog), I've been on the trainer A LOT. At some point, I must have adjusted the roller too tightly too, because it seems I've worn a groove into the roller.

Anyway, the thing was was a hassle to actually mount the bike on, and the resistance felt unnatural...generally the problems you encounter with a mag trainer with a cheap clamp. Well, seeing as the flywheel is in pretty bad condition, I figured it was time for a new trainer (and an early Christmas present).
