Product Description

The Topeak Alien II multi-tool is pretty incredible. It's an entire tool box that fits comfortably into your hydration pack or jersey pocket. There are 26 tools in all, and short of a cracked frame or complete fork overhaul, you should be able to fix just about anything with the Alien II. The Topeak Alien II combines pressed stainless steel with engineering-grade plastic for lightweight durability. It also splits apart for ease of use. The Alien II comes with a chain tool and a chain hook to assist with chain repairs. It also comes with a 15mm pedal wrench and two tire levers. As for Allen bits, this Alien has them covered from 2 to 10mm, with a T25 Torx also included. 8, 9, and 10mm box-end wrenches, along with 14, and 15-gauge spoke wrenches, and #2 Phillips/flat-head screwdrivers, round out the Alien II's features.

Indestructible!!
I have been using this tool for two years now. Today I felt an urge to tell how strong this tool is. I have use most of the items in the tool without any complaint. But the major test happened today: I had to take a couple of Candy 3 Crank Brothers pedals from one bike and put them in another one. These pedals were totally stuck with no grease at all used when installed. I needed to use the 8mm allen wrench to get them out. My bare hand force was clearly not enough to release the pedals, so I decided to use a 2 foot steel tube to help as a enormous lever (see pictures!) with the Topeak inside the tube. I had to produce so much force (extreme force!) even with this huge lever that I thought that this tool would very likely break into pieces. But I really needed the pedals in a different bike so decided to run the risk of breaking the tool. To my surprise I managed to take out the two pedals and both the Allen wrench and the case did not show even the slightest sign of bending, wear, whatsoever. In fact after installation in the new bike (now with grease), everything went back in place without any effort, and the two halfs of the tool attached as when new. Congratulations Topeak for a fantastic and indestructible multi-tool!!

There have been a few times I wished I had a wrench in my tool bag rather than trying to get by with pliers. This tool has a great selection of wrench sizes. I also like that the tool splits in half so I can use an Allen key on one end and a wrench on the other end when a bolt works loose. It took me a few minutes to figure out how to press down on the safety catch to release the knife blade or release a tool that had been extended. Now that I know where to press, I like the safety catch. Heavier than the tool it is replacing because this does more.

When I read the description for this multitool, I initially thought it had too many unnecessary parts. It turns out my roommate has this exact same multitool, so I've been using it a bit.

I've found that the location of each little tool is actually very well thought out. The two halves come apart not only for simple convenience, but also for you to use the tools from one half to give you extra leverage turning a tool on the other half. Examples: When using the chain pin tool on a stuck pin, the 5-mm Allen wrench is on the other half so you can use it to give you extra leverage. When using the mini pedal wrench (which is quite short, about 75% the length of the whole multitool), you can give yourself extra leverage on the pedals by inserting the 8-mm Allen key from the heavy half into the smallest hole on the pedal wrench. This gives you more than double the original wrench length, a much stronger lever.

Note on the mini pedal wrench: The material seems to be the same as the 8-10mm wrenches, but different from the Allen wrenches. I would have felt better with a steel pedal wrench, but that might have just been too heavy and this one seemed to work just fine for tightening my pedals a bit before I could make it over to my bike shop.

So after all this, I ordered one for myself and it came today. I noticed my roommate's tools would fold out without resistance (except the knife--that one uses a locking mechanism so it never accidentally deploys). My new one was much tighter. I found out that on the sides of each half, there are different sized hex holes so you can use an Allen wrench from the opposite half to tighten or loosen the folding resistance to your liking. The 4-mm on the smaller half adjusts resistance on the heavy half, and the 2.5-mm on the heavy half adjusts the resistance on the smaller half.

The knife is indeed VERY sharp and seems highly durable, and requires considerable manual effort to unfold. (Or maybe that's just my weak girl hands.) This is a good thing. I am zero percent worried that it will ever accidentally open. Folding likewise requires manual effort, but just be careful not to fold it onto your fingers because that blade is quick.

Overall, I feel much better having one for myself. If you want to pack light and aren't wandering far from civilization, you can probably just take the smaller half alone. If you're going on a camping trip, absolutely take the whole thing.

Another note that I think a lot of people will miss about these tools is that each half's black plastic base is actually a plastic tire lever. They're identical. The plastic is hard and rigid, and won't scratch the rims or wheel. I didn't see this at first when I was using the tools, I thought the plastic shapes were just aesthetic and for fitting the halves together. They don't really show this off in any pictures or diagrams but it's a really nice touch!

Thanks for reading and if you have any questions please feel free to comment.

Several years ago, I became serious about mountain biking again after not riding a bike since acquiring my driver's license. I had an older version of this tool back then and with the upgrades they made to it, including a chain tool, I decided I had to have the newer version.

I have used this tool to fix all kinds of trail-side problems with my (and by buddies') bike. All of the tools are useful and well thought-out. I keep this tool in its nylon pouch on the waist strap of my Camelbak with several quick links in the small flap on the Velcro closure of the pouch.

I ran into one problem with it though, which would have brought the tool down to 3 stars, but the way Topeak handled the issue put it back to 5. I had to use the pedal wrench to fix an issue trailside. In the literature about this tool it says that the pedal wrench is for emergencies only, not general use, and man were they right. The tool did its job, but after using it (and having to crank on it pretty hard) the pedal wrench flexed to the point that the wrench would no longer fit properly on a pedal spindle.

I called Topeak and the customer service guy asked what the broken part was, asked for my name and address, and told me he was shipping a new wrench part to me immediately! He didn't ask for receipts, where, or when I bought it, how I was using it when it broke, or anything. No kidding, I received the replacement part, in factory packaging, three days later! That, my friends, is the way companies should stand behind their products! Well done Topeak!

If you want a tool that allows you to fix just about any trailside problem, from a company which stands behind its product, you need a Topeak Alien II multi-tool!
