You are going to break your rear sub frame under your seat if you ride dirt roads and strap your luggage behind you, believe me. It’s not a case of ‘ if ‘ it will happen it is ‘ when’ it will happen. To avoid this we make an aluminium frame brace that bolts on to support the rear section of the frame against breakage. It is all bright and shiny so looks great as well. There are a lot of other frame braces around that do not work or are extremely heavy so beware. Ours have carried 30kg on them for 48,000km with no trouble so are one of the better ones to purchase.
