Blackburn Grid 13 Multi-Tool

by Brian Mullin on July 7, 2016


The versatile Blackburn Grid 13 Multi-Tool provides most of the commonly required tools for mountain biking and can easily be carried in a pocket or a pack. The all metal Grid 13 is well-made and tough, and it fits nicely in your hand and features a baker’s dozen of innovative and functional tools. The Grid 13 has a sweet looking satin finish, weighs 142 grams and retails for $19.99.



The Grid 13 is decently compact tool and weighs in at a respectable 142 grams or 5 ounces. It has 13 tools, ranging from 1.5mm to 8mm hex keys, T25 and T30 Torx wrenches, a flathead screwdriver and a multi- function tool. The Allen wrenches include straight armed 1.5mm, 3mm, 5mm, 6mm and a stubby hollow 8mm along with “L” shaped 2mm, 2.5mm, and 4mm keys. There are a single flathead screwdriver and two Torx wrenches, a T25 and T30. The single multi-function tool combines a disc brake pad spreader, a Presta core remover, and a bottle opener in an all-in-one unit. All of the tools are sandwiched between two forged satin finished plates, and everything is held in place with an axle and a bolt, both of which use 2.5mm hex heads so everything can be easily tightened when required.



It had all the necessary hex and Torx sizes needed for most anything on a mountain bike, and the only thing it’s missing is a chain breaker tool, and although it’s quite useful, it adds weight, size, and complexity to a multi-tool. I liked the “L” shaped hex keys as they were useful when working in tight and cumbersome spaces, and the 4mm size was especially functional when tightening and loosening saddle clamps. The angled hex keys might not work in all situations such as when a normal straight shape would be more practical. The multi-functional tool was innovative, offering a useful brake pad spreader and Presta core remover and bottle opener. The pad spreader and core remover are excellent items, and I found them extremely helpful out on the trail when unforeseen issues happen. I don’t drink much, so the bottle opening tool wasn’t the most useful for myself, but almost all of my biking buddies would find it a necessity!


Bottom Line

The Blackburn Grid 13 Multi-Tool is rugged and compact and versatile and offers 13 tools, including 1.5mm to 8mm hex keys, T25, and T30 Torx wrenches, a flathead screwdriver and a multi- function tool. All of the typical tools were functional for most mountain biking adjustments, and the real highlight was the multi-functional tool which offers a brake pad spreader and Presta core remover and bottle opener. The “L” shaped hex keys were also useful and allowed working on bolts in tight locations.
