I'm thinking about getting some of the Nashbar reduced radius rollers to stay in shape over the long (3 month+) snowy/slushy season here. For 119.00 they seem pretty affordable. Have any of you used or own these? How do you like them with your fixed gear? Are they very noisy? Does it suck to not have a resistance unit?
