I've actually put too much storage on my bike
So now I have two under seat bags (one per side), an old man mountain rack with two bike bins, and space between the bins for more things... I feel a little too over prepared for most situations and am thinking of leaving things off now.
I still haven't found the best way to carry my guitar around. I have a soft bag and basically I bungie it across the top of the bike bins and that is fine but it doesn't feel like the ultimate way to carry it yet.
If I had to do it again, I would go the hardware store and simply modify a cheap rack from canadian tire but... this old man mountain one should last forever.
