I have been commuting to work a few times a week and my back gets super sweaty with a backpack.
I decided to purchase a Topeak DynaPack DX Seat Bag. It's really cool because it just hooks onto the seat post. It's just big enough for me to carry my clothes, lunch, and tubes/pump.
I was about to install it when I was reading the directions and it says IMPORTANT NOTES:
DynaPack is not suitable or intended to be used with carbon fiber seatposts.
I wish that they would have stated this on their web page which listed the product details. I have a carbon seat post.
I ride Profile aero bars mounted on to carbon handlebars and I have no issues.
Carbon fiber is really strong, do you think mounting this bag (2 lbs) plus clothes and lunch (3 lbs) will cause damage to the carbon seat post? I could purchase an aluminium seat post, but wanted to see what ya all think.
