Carbon Fiber Seatpost and Rack ?

I have a rack I would like to mount on my road bike which has a carbon fiber
seatpost. Any reason I shouldn't do this? Could it damage the seatpost in
any way? It's the type of rack which bolts onto the seatpost without any
other support.

TIA....Dave

Personally I wouldn't do it

_ This is a really bad idea. Carbon fiber is very suseptible to
point stress and a single scratch can be the starting point for
catastrophic failure. I've broken lot's of carbon fiber stuff
windsurfing and it almost always starts with a single scratch.

_ Personally, I would never use a carbon fiber seatpost, but
that's probably my own paranoia since I've see so much carbon
fiber components destroyed windsurfing.

_ Get a low budget alloy seatpost to use with your rack, if
you're carrying a rack a few ounces won't matter.

Bad idea, get an extra seatpost if you need to mount that rack.

Well, it's not really about weight. It's about comfort. The carbon fiber
seatpost is supposed to absorb more road vibration.

Whether it works or not, I couldn't positively say, but the bike is
comfortable to ride.

_ Stop reading the marketing. Carbon fiber vibrates just as well
as aluminum.

_ Tires and tire pressure make a much bigger difference in
road comfort than any seatpost short of something like this

_ I've got one and so far ( about 4 months ) I really like it.
Works just fine with the beam rack...
