Most of the saddle bags on the market these days are shit. Thats why we have companies like Chrome making gear that actually works. I've been using the Chrome Tool Roll Small for over seven months now and it's been getting the job done. It's big enough to carry a tube, C02 cartridge, multi tool and a tire lever with a little room to spare.
For $25 you can't really go wrong.
Am I looking for something better? Sure. I always am.
The Chrome Tool Roll has served me well and I definitely recommend it to someone looking for an alternative to the shit most LBS's stock.
