This heavy duty tool roll comes in two sizes.
For race day repairs, the Large holds wrenches and large tools in two main pockets and one large mesh pocket. It's real tool roll with the essentials for a mechanic stranded on a desert island.
The Small version has two pockets for levers, tube, and cartridge for emergency bike repairs -- mounts like a saddle bag, but you won't have to dump the contents on the ground to see everything at once.
Strap it shut and carry it away. These rolls don't sacrifice durability for convenience.
