In the past ten years I’ve probably bought over 20 different cycling-specific multi-tools. I have five bikes and carry a multi-tool in the seat bag of each one. It seems like every time I find a multi-tool with a new feature I have to buy it (I am an impulse buyer). There is one feature on the Topeak Mini 18+ Multi-tool that made me want it instantly, i.e., the pad spreader for disc brakes. If you have a mountain bike (or even a road bike) with hydraulic disc brakes you probably already know that if you accidentally squeeze the brake lever while changing a tire the brake pads will close and are nearly impossible to open again without a special tool. One time I made this mistake and had to use a knife to trim down a credit card to pry the pads open (then I had to order a replacement card once I got home).
Here is a breakdown of the hardened steel tools in the Topeak Mini 18+ Multi-tool: Allen Wrenches (2, 2-L, 2.5, 3, 4, 5, 6, 8, and 10mm), two spoke wrenches (15 and 14g), chain tool, T25 Torx bit, chain pin breaker, bottle opener, pad spreader for disc brakes, and both a Philips and flat head screwdriver. This multi-tool also has an anodized aluminum tire lever—please note that this particular lever is designed for emergency use only. And, like most of the other Topeak multi-tools, it comes with a Neoprene storage bag. This product weights 6.5 ounces (185 g).
A couple of notes about two of the tools: The chain tool in the Mini 18+ works well, but I would rather use a full size chain tool when possible—but certainly would never carry the big one with me due to the weight. The T25 Torx bit will easily adjust mechanical disc brakes—if you have disc brakes on your bike you really need to carry a T25 Torx bit with you.
The Topeak Mini 18+ Multi-tool retails for around $33 and is available at any well-stocked bike shop. This product comes with a 2-year warranty (see Topeak’s Website for complete details). You can find this tool at a lower price on Amazon.com, but do yourself a favor and support your local bike shop.
If the Topeak Mini 18+ Multi-tool does not suit your needs, Topeak has many other tools to choose from. Here are a few links to some of their other multi-tools I’ve reviewed: The Topeak Mini 9 Pro Multi-tool has all the Allen wrenches you will need for most modern road bikes (2, 2.5, 3, 4, 5, 6 mm), along with two tire levers. The Topeak Hexus II Multi-tool has 16 well designed hardened steel tools and it fits into an easy-to-hold composite body. The Topeak Alien II is the “mother of all multi-tools” and includes 26 tools, including eight Allen wrenches (2/2.5/3/4/5/6/8/10mm), box wrenches (two each of 8/9/10mm), a T25 Torx wrench, Phillips and flat-head screwdrivers, two spoke wrenches, two tire levers, mini pedal wrench, stainless steel knife, bottle opener, a cast Cromoly steel chain tool and a steel wire chain hook.
