We don't have a trainer but do have Rollers. I can be balance challenged on the rollers so the DH bought me the fork stand and I have zero excuse for not riding indoors. In the process of setting it all up the other day, I manged to smack my knee on the top of the fork stand - talk about pain. I did manage to hobble onto my bike and had a productive 35 minute workout w/intervals but the next day I was certainly limping. Will climb back on today as it is still only 1 degrees outside Spring can't arrive soon enough
