[Closed] Touring on a road bike... Luggage?

Hi all,

I'm planning on doing some touring but only have a lightweight road bike to use. Planning on getting a fairly large handlebar bag but am going to need some more luggage.

What options do other people go for? Thinking of opting for a rack that attaches to the seatpost and fitting another bag to that but a little concerned my carbon frame and seatpost aren't really designed for carrying that kind of load?

Cheers
Ben
