Next weekend is a 60 kilometre long trail ride. We normally only ride 15 kilometre loops twice before stopping to re-fuel, rest, drink and eat.
We normally only carry water, first aid products and an air pump. But this trail ride we need to take food, tools, spare tube and a two way radio.
Thus we need some way to carry the extra 5 kilos of weight.
I came up with an idea and drew it on my cad system. I printed out the design and glued it to a sheet of 1.6mm or 1/16th" ali.
Then the usual took place cut and shape.
