Options for Bag on a Road Bike - 300K Brevet - Rando
I did my first 200K last year and plan another on my bike next month. In April I plan to tackle a 300K and am now concerned about being able to carry more while on the bike.
My bike is a Specialized Roubaix SL3 Pro (yes I know it may not be a good rando or touring bike because it is a road bike). I do centuries all the time but an unsupported 300K has me a bit concerned that I'm not carrying enough.
I currently have a small seat bag that carries two CO2, a tube and a small toolkit. When I ride I also carry an extra tube, tire levels, my wallet, phone and snacks in my cycling jersey pockets.
I've done a little research and have seen some handlebar bags. Another alternative are some lightweight racks that you can put a seperate bag on. The rack attaches to the seat/seat posts. For example: Arkel brand
For my 300K I'd like to be able to carry a little more stuff like a couple more CO2, maybe another tube, my jacket (which can be rolled up very small) and some extra snacks.
So will one of those rack/bag combos on the seat be too heavy for my bike? To me, that looks like a good option as long as I don't pile a bunch of heavy stuff in it. The handlbar bags look a bit bulky to me...don't know.
Or should I just get a larger seat bag?
Ideas are welcome, but don't rag on me for doing a 300K rando on a road bike ;) One of these days my N+1 will be more of a touring bike but for now this is working.
Pictures would be good if you have a setup to suggest.
