|Trainers bend frames: true or false?||2ride|

|I am planning on buying a trainer (probably the 1Up Trainer) and need to know if the stories I've heard about trainers possibly bending frames are accurate. I suppose with the way trainers are attached to the frame, coupled with the stress pedaling, a bent frame is not out of the realm of possiblity. How common is this problem?
BTW, I have rollers but would like something else to mix up the off season training routine.
Thanks for the input.

|I have used my Cyclops trainer 20-30 times and haven't noticed any problem... I use a Cannondale 2000 on it and do get on it pretty hard.|

|Why not add a resistance unit to your rollers?|

|One time I bent my girlfriend like a pretzel, but I don't think it damaged her frame.... : )|

|The only way I could see a frame bent is if you were out of the saddle trying to do some sort of sprint. I ride mine about six days a month for the last two years and have no issues with frame damage. Mine connects to the rear skewer and is a mag trainer. The only thing it does trash is the rear tires. It will devour rear tires. I bought a cheap rear 105 wheel on ebay with a Kenda Koncept tire just to use on the trainer. About 30 bucks total investment. One more tip I learned today. Don't use a tube with a patch. The heat generated on the drum will soften the glue and the patch will seperate. I couldn't believe I got a flat while riding the trainer! How is that for bad mojo.|

|Certain trainers that have fork mounts, if used incorrectly can potentially damage the dropouts on the fork, but not typically the frame. Most lateral torsion from riding is absorbed by the front wheel, tire, and transferred by movement of the fork. When this is restricted by attachment at front fork, most torsion is restricted to the stem, handlebars and dropouts on the fork. So, inappropriate activity on the trainer could POTENTIALLY damage dropouts, particularly the front, but would be pretty uncommon.
Things that would increase the propensity of frame/fork damage, would be uneven floor surfaces, bent or damaged trainers, improper setup of bike to trainer, heavier riders, previously bent or damaged frames, and unforseen trainer accidents in which the rider would fall to either side while on the bike...
