Full set up
What else do I need when purchasing the topeak RX trunk bag dxp with side panniers? Which beam rack? Do i buy a beam rack that has side frames already installed? Is the above trunk bag the biggest on the market? Will this set-up hang onto a seat post that is carbon fibre or do I need an alloy (or other) seat post?
Thanks for answering all my questions!
You want the Topeak QR Beam Rack RX with V type large frames (ref 5360137927). You attach the v-sides to the rack (and it's straightforward to do). You must use a non-carbon seat post given extra load. Also worth buying the waterproof cover (I don't have reference to hand, but search using same Topeak Rx trunk bag dxp + cover).
