Storage Box for my Gravel Bike (=> G-BOX).

In the box there is enough room for multi-tool, tube, tubeless sealant, brake-pads, tubeless-valves. The thing is designed around a 56 Focus Mares frame and fits like a glove. Due to the foam rubber on the bottom other bike frames with "classic geometry" (round tubing, 74° seat angle) also worked (f.e. Specialized Crux).

• Contact to Frame is protected by 3mm thick strips of foam rubber.
• Box is mounted using Velcro-Fasteners, I use Lupine. Long version for bottom tube, short version for seat tube. https://www.lupine-shop.com/en/accessoires-and-parts/velcro/1067/velcro-battery-extra-long https://www.lupine-shop.com/en/accessoires-and-parts/velcro/1068/velcro-battery-short
• Top cover is fixed using elastic shoe lace. https://www.aliexpress.com/item/32966937440.html?spm=a2g0s.9042311.0.0.27424c4dugZjZg
• Sealant or chain-lube needs to be refilled into a smaller container. I use 30ml bottles: https://www.flakado.de/flaschen/kunststoffflaschen/rundflasche/4800/30-ml-rundflasche-liquid-natur-din-18-gewinde
