Trek seems to have a nice interchange system. Does anyone use this system or one like it? Reviews? Can I use it on a carbon seatpost and a carbon frame? Where do I find the rack online?

Thanks!

If you have the braze-ons on your frame for a rack, you can use those.
That doesn't address your "remove it for a speedy 20-miler" issue, but I've seen folks ride plenty speedy with a(n empty) rack on the back of their bike. Looks Fred to those who care, but....well...there it is.

Generally, clamp-on racks (such as this) should NOT be used on carbon seatposts.

If you have no way to attach a standard rack to your frame and have a carbon seatpost, generally, you're SOL for carrying that trunk rack. Sorry.
