makataack,
Thanks for the info.... have lots of room in my basement, so space and noise not an issue.... I'm a bit worried about falling off rollers, but am worried trainer will put more wear and tear on my bike.
any advice from you on the minoura rollers? or others?
Thanks
I guess the wear and tear from a frame in a trainer comes mostly from any flex along the rear triangle as you do hard stuff like get off the saddle to sprint (seated or off) or simulate climbing when in a high gear. If you're just spinning like you would on rollers, I suspect the wear is minimal.
Since my roller drums are larger diameter than the drums on any trainers I've seen, I think I get less wear on my tires... but that's offset by the fact that both tires are now spinning/wearing.
Also, a side benefit for my rollers is that my computer still works since the sensor is clipped to the front fork. If you wanted your computer to work with a trainer, you'd have to make sure your sensor is clipped to the chainstay or something. That won't work with my wireless computer! Of course, either way, the speed reading is a bit meaningless... I only use it for the "ATM" or automatic timed ride feature. Of course, this runs down the computer & transmitter battery for a feature that I could get with my stopwatch!
I don't know much about the minoura rollers. I have a friend with them, but they haven't been on them regularly. The ones I got are made from a company called "Kreitler" but I don't know what model I have, other than the they have all aluminum drums, so I assume they're the "Alloy" model. The LBS guys said it's a great deal, especially since they're free... but they're almost $600 dollars new according to Colorado Cyclist with a fan resistance unit, that I didn't get with my set. I don't know if the bulk of the price is from the fan unit or what... but the next closest price is $300 for a set that aren't all aluminum.
Anyway, I suspect mine are from a few years back... and they have some scratches and gouges on the aluminum drums (no doubt from storage/dirty tires/etc that the previous owner made). Either way, they seem indestructable... very simple construction. Trainers are obviously more complicated devices (and fluid trainers used to have a terrible reputation for messy failures).
Good luck!
