tail rack bag
I'm sure this has been discussed but I'm too lazy to search ... I have popped through a couple of tail rack bags that I use when riding my GSA off road. The last one was the Coretech sport bag. After some desert woops yesterday, one of the bungee cord attachments ripped right through the bag and off came the bag. Biggest problem was it was still partially attached to the rack but now wrapping itself into the rear wheel.
I typically carry my tool roll, a small compressor, puncture repair kit. few cam straps, flash light and maybe spare gloves or goggles. What seems to be the best bag for the job and will last a while ... most importantly stay secrured to the bike?
