Since this thread has been dug up recently, I'll post an update. 8 years on and I still enjoy my rollers. I bring them down from the loft in mid January and take them back up at the end of March (today). As well as real cycling outdoors, I have 3 choices for winter cardio: rollers, stationary trainer and NordicTrac ski machine, which help stave off the degradation of cycling fitness from my peak in the fall. I enjoy all three. The rollers are a key part of the program.
A couple of weeks ago I was rolling along nicely, good tunes on the stereo, when phipfffff, the rollers quit working and I noticed the belt sliding across the floor in front of me. After only 30 sumpthin years the original belt broke and retired. Lousy luck, eh? I ordered a replacement from Kreitler/Mountain Racing Products and a week later I was back on the rivet. Great service and the new belt fit perfectly. Me n de rollers are good for another 30 years.

My setup. DIY wood mounting block (for each side) with holes for the middle feet to ensure the unit does not move. Left of the bike is the huge sliding door in my shop. I block that in the position shown and it and the door jam frame me safely. Good tunes. stare at a mark on the opposite wall, look out the windows a bit and grind along. I really do think it smooths out my pedaling and improves balance. I'll keep em.
As part of the rights of spring (converting the tractor from snow blowing to mowing. pulling up the snow stakes from along the driveway, etc) I also reconfigured the Cannondale back to summer mode. I'll ride that under sunny skies tomorrow.
