my idea for a mountian bike seat wedge pack, came from the failure of the stock units faulty zipper, and bad mounting location, you can pick one up at any decent mountian bike shop, i used a blackburn wedge pack made to fit under a bike seat, it will fit right behind the front plate right above the back of the headlight, it has a heavy plastic liner inside so it can be drilled to the plate with a couple of bolts, painted them white to match the plate, it came in black so it will match just about any bike, and its made of heavy nylon mesh and has heavy duty zipper, it fits perfect between the crossbar and the front plate, the only drawback is im not sure that it will work unless you do away with the oddometer, it holds plenty of stuff, and is a good mod that keeps your tools put and out of harms way, hope this helps, if you need more info get back to me,
