I'll put this here, but it might end up being more for the three speed crowd. I'm thinking of getting an indoor bike trainer for this winter. I don't want to call it a New Year's Resolution cause then it won't come true..... I would like one of the ones that raises the rear wheel and not the front one. Is there one of these that might work with a three speed bike or will they only work with modern bikes? As another option.....has anyone tried the one where you have to balance and both wheels are in rollers?
