Heat Issues with Carbon Fiber Frames(10 posts)

Heat Issues with Carbon Fiber FramesHelduser
Apr 15, 2002 9:49 AM
I have a trek 5200 oclv 120 frame w/ Chorus 10 components, and ksyrium wheels, etc.

Should I be concerned with storing it in the car when temperatures reach 80 to 100 degrees? Are there any issues with temperature extremes and carbon fiber (epoxy joints)? Would you happen to know of the min and max recommended temperatures to keep the bike safe.

Thanks in advance,
Mike

I read somewhere, but I can't remember at all where, that it is not recomended leaving the bike in extreme heat, that includes cars.

Extreme heat? Yeah, sure.

Mike, I live in Texas and ride in 100 degree temps all summer. All my carbon bikes that are kept in the garage. I've never had a problem. That being said, I don't reccommend keeping any bike stored in a car when the temp reaches 100 degrees.

Thanks. I appreciate the response. I finally got off my butt and looked it up in the trek owner's manual. They recommend keeping the bike away from temperatures at or over 180 degrees. So I think I'm safe wife keeping it in the car while I'm at work on a very hot day.

The only problem I've had keeping my bike in the car is the components get too hot to the touch. Make sure you cover your handle bars with a towel

Frame will be fine - you need much higher temps. for anything to happen. Think about it this way - a lot of us that have riden OCLV's in beastly temps would've been in trouble a long time ago. It takes several hundred degrees to affect the epoxy matrix.

I will caution you on one thing - the temperature inside a closed car gets a lot hotter than 100 degrees in the summer with the windows closed - you could see 140. Your biggest concern might be the tires inflated to 120 psi, but remember that when you use the Ideal Gas Law ( PV=nRT) the temp. is absolute (Kelvin for Celcius and Rankin for Farenheit).

What you really need to do is forget about the temp. issue and go ride. ;-)

I would but I have this little issue of having to work to actually make some cash to finish making the payments on my speedster.

So it has to sit in my hot car until lunch and then again until after work.

If the heat generated by some of the rocket like decents I make on my '52 dont melt it nothing will!!! (yea right)
