Holds all of my gear, except my bike rack!
I was a little worried when I ordered this, since both my helmet and MTB shoes are larger than most. I have T.H.E. 's F14 helmet which is like a 1/2 helmet and the Adidas Plush shoes, which are like high-tops. The helmet fits in the center section of the bag. The shoes fit where the helmet is pictured in the ad. I have just about EVERYTHING in this monster; spare tubes, spare tire, tools, pumps, etc.... Granted, its quite heavy now that its fully loaded, but I know where all of my "stuff" is. No more "oh mang I forgot that at home somewhere!"
