I like your mods, Jaume. I really like your "casual tool box" and I like where you put it, simple, elegant, practical, and low center of gravity. I wonder though if it would be better that you position the tube on top of the engine guard bar instead of under it as shown on your pic. Why? I reckon it would minimize the possibility of getting hit on some tough off-road ground, and let the bashplate take the hit first. Have you tested how waterproof it is? I mean literally sink the whole tube under water, similar to when you ride cross a knee-deep high river. I recall seeing some similar tube structure sold at outdoor/camping stores that is waterproof. Of course, I would double bag it in an Ortlieb or something similar. It looks like your tube could possibly hold a couple cans of chain cleaners/lubs in addition to tools too. That would be bonus. Still, great stuff, Jaume. ALso, the thermometer and the compass are exactly what I have been looking for. Perfect.
