A friend stopped by today and I was discussing this with him when he pointed out to me that the resistance unit on these rollers probably isn't stock...and appears to be an older Minoura Magturbo resistance unit that could have been added later. With this information, I've found some other options that should be cheaper than $300 for sure. Surely won't be as nice as the Kreitler Rollers, but should be good enough for the limited use I'll give them. Afterall, I can do my fitness training outdoors most of the time, and only use rollers for technique training.
