ok so this year i'm REALLY going to try to keep in shape during the winter....i mean it. i have a trainer but i really can't stand it. my computer measures from the front wheel so i get no info from that on the trainer. i have a POV dvd that helps a bit but not much. i'm hoping with the bonus of seeing the "miles" i'm riding plus the thrill of almost falling off will keep me going. anyone have better success with rollers over trainers?
