Stationary trainers,can they cause frame fatigue/damage?kentuckyjoe

Just ordered a clcleops fluid 2 and was thinking that it looks as if this type of trainer attached to the rear wheel only, would put alot of stress on the rear part of the frame.I ride a aluminum GT frame, weigh about 235 and that makes me even a bit more i being paranoid or is this a real risk? thanks all,Joe

It's a risk, especially if you stand and hammer. That's why I use a $10 yard sale beater for my trainer bike.

Where in Kentucky?

while riding one. Don't know how he was using the trainer (ie properly, improperly, spinning, hammering). Don't know how common this is though.

I've heard from a reputable framebuilder that it indeed can hurt your frame. Bike frames aren't designed for that kind of stress.

Use a beater or stick to rollers.
Yep. This is the definitve answerAndante

Waterford Bicycle even makes thier frames with reinforced chainstays if you are going to use it one a trainer. This is from thier website:

Should I use my Waterford on my Windtrainer?

Only if you're careful. When you ride on the road, your bike sways and leans as you shift your weight from side to side. Clamp it into a wind trainer, all that force is absorbed by the dropout, dramatically accelerating frame fatigue. What can you do?

Avoid wind trainers which clamp at the bottom bracket. These can be particularly damaging to your bike. Trainers which clamp at the rear dropouts put less stress on the frame.
Supplement your wind trainer with a set of rollers which, since they have no such clamping, take less of a toll on the frame. Rollers help you develop important handling skills which you can't get from a regular wind trainer.
Use your "beater" frame on your wind trainer. This can mean many more seasons for your Waterford frameset.
Tell us if you plan to buy a Waterford for use with a wind trainer. We can substitute extra-strong chainstays and seatstays which compensate for the extra stress and strain.
What else should I know about indoor training?

Besides the extra wear and tear from wind trainers, don't forget about other considerations associated with indoor training.

Among such considerations, protecting your frame from sweat is most important. When on the road, wind dramatically reduces the amount of sweat which drips onto the frame during riding. When riding indoors, less evaporation takes place and some training areas are quite warm. This means a lot more sweat hitting the frame. Be sure to clean off your frame after every workout! An occasional waxing provides additional protection.

Lube it up: Just because you train indoors doesn't mean you can ignore normal mechanical maintenance. In particular, make sure the drive train and head set are properly lubricated before every ride. Not only does this extend your bike's life, it makes your spring ramp up easier.

Keep it warm or keep it cold: Keep your bike indoors if it is your trainer and outdoors if it's your commuter bike. Great changes in temperature inevitably create condensation on both inside and outside surfaces - expecially when you bring your bike in from the cold.

It's just like how an ice-cold glass sweats on a hot summer day. If you plan on riding all winter, store your outdoor bike in the cold. Not only does this eliminate condensation from forming, it also keeps your bike in closer adjustment since your cables don't contract and expand with the temperature changes.
