Topeak 60102353 Alien II 31-Function Bicycle Tool

This thing is incredible. I know there are lots of similar items available, so I can't say this particular brand or configuration is indispensable. However, I can say that this one has served me well for about 25,000 miles now! Allen keys in all the required sizes, a few wrench heads, a nifty little detachable wrench that can also be used to brace nuts on the backside while screwing the bolt in from the front, a pedal wrench attachment that saves you from having to carry a whole separate unit, a chainlink breaker (hope you never have to use that one!), and a knife for just in case. Carry this, a patch kit, and an kevlar emergency spoke and you are just about ready for a world tour! One note: be sure to dry it off if you've been riding in the rain. I messed up and left mine in its sheath inside my saddle bag, which got totally drenched. I must have left it in for a few weeks after that. Now there's some staining and corrosion. I'm sure if I had taken care of it promptly it would have kept its sheen. In any case, it still works great and I wouldn't buy anything else!

Kinda like a Leatherman multitool, but specifically made for bikes, this high quality tool is a great asset to any bike kit. I went through my bike to determine what tools I'd need on the road/trail and this tool set more than meets those requirements. There are more tools than most of us will ever use, and it's heavier that some weight conscious riders will accept, but for those of us who ride without vehicular backup, this tool set provides peace of mind. The tools are made well with enough metal to provide the strength necessary to prevent damage to the tool or the nuts and bolts it is used on. The chain tool is impressive, too. The design is well thought out, such as placing the allen for the chain tool on one half and the chain tool on the other so there is enough leverage to make it work. Some chain tools provide a small holding tab that is quite insufficient for the torque required to remove or install a chain pin. Even the adjustment nuts for the tool are different sizes so that the opposite side has a hex wrench to tighten or loosen the deployment of the tools. The pedal wrench will easily snug down a loose pedal, but as expected, it certainly shouldn't be used to try to break one loose. I like the added quality of etched labels on the tools, too. All in all, a great, well engineered and built portable tool set.

This is a great bike tool. However, it made its way from my bike into my tool chest when I moved since I began using it for all kinds of assembly around the house (due mostly to IKEA loving hex bolts). Pros: -detachable in the middle makes it easier to handle -more tools than I knew what to do with meant I could always find something to fit my immediately need -compact design and carrying case fit easily into my under the seat bag on my bike -great quality materials Cons: -Goldilocks problem: --a bit heavy if you're just going to use it for necessary road repairs --probably not comfortably enough if you're going to rely on it to do full on bike repairs -The two halves would come apart pretty frequently...I think I didn't lock it in place well enough -It could sometimes get frustrating to get some of the other tools out because they were all packed in pretty tightly Overall, a great purchase and one I'm happy I made. It is definitely overkill for just something you're going to keep on your bike for roadside fixes, but I guess it's better to always be prepared.

This tool is really nice for most things. It can manage many minor modifications and repairs to my bike. The built-in tire levers, knife, and various hex wrenches are nice. However, if you need to remove a pedal that requires a hex wrench, you will need another tool. Examples of such a pedal include the Shimano M520 or M540. This multitool, although it has 6mm, 8mm, and 10mm hex wrenches, cannot generate enough torque to remove a pedal with a hex fitting. I really, really tried removing one of my pedals with this, and almost hurt myself in the process. It did not budge. This was because the size of the 8mm hex wrench on this tool is about 2 inches. The next day, I picked up Pedro's 8mm Hex Pedal Wrench, and the pedal popped right off. I was actually surprised at how trivial it was with a proper wrench. Pedro's wrench is much larger, with an 8 inch handle and an ergonomic grip. It allowed me to get a lot of leverage. Buy a dedicated pedal wrench in addition to this tool and you won't be disappointed.

The perfect balance between compact and useful. It's not a whole bike shop in a pouch, but it's remarkable just how many tools they jam into such a tiny space. And they are the tools to do the jobs you actually need to do when you're out on the road and the nearest real bike shop is forty miles away. I want to add one more plus to the general praise that this tool deservedly gets (good value, tools work, compact) and that's customer service. One of the tools in my Alien had a defect. Nobody's fault. These things happen in mass manufacturing. Topeak sent me a replacement for the defective tool, and I had it in less than a week. What you need in today's world of online shopping, since there isn't a shop owner you can go complain to if something isn't right, is a vendor / manufacturer who stands by their goods. Topeak does. Good stuff, fair price, and they make it right, fast, if something is wrong.

I've recently gotten into road biking again and wanted a small universal tool to be able to take with me on rides in the event of mechanical problems. This tool has more functions than I will probably ever use, hopefully. I say hopefully in that if I am using some of the tools, I've had a mechanical breakdown and who wants that. :) The storage pouch that it comes with is perfectly sized to hold the tool tight in place. Added with that the belt clip type setup allowed me to clip it to the underside of my seat bag and not take up space within the bag. I checked to make sure the device stayed in place several times of some rough terrain and it held fine. There is also an option mounting device that will allow you to clip it to the bike as noted in the instruction manual. The tool is well made and versatile. It's compact design and storage case make it an excellent add-on for any cyclist.

I bought this tool in May 2012 and have already had the opportunity to use it several times. It has all the standard tools to fit my Bianchi Boardwalk and my wife's Cannondale f9 and then some. This tool is a must have item for the cycling enthusiast looking for piece of mind while on long trips. The chain break is stronger than the Park Tools multitool (that broke on me after one use on the bike I leave in FL.) I use it frequently on trips where I need to fine tune derailluers, brakes, etc. and proves itself to be invaluable in emegency repairs of all kinds while on the road, both for myself and other riders in our group. All of the Topeak products I have purchsed have proven to be well thought out, reliable and sturdy. If you're looking for a multitool for your bike, look no further, you just found it. Buy with confidence.

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.

Serves for most cases, fits for riding alone and for small adjustments at home. quality of tool is not excellent but enough for couple of years of using. heavy because of many functions

MULTIHERRAMIENTA PARA LA BICICLETA DE MUY BUENA CALIDAD, NO SALGO SIN ELLA, TIENE UNA NAVAJA A DIFERENCIA DE OTROS SEMEJANTES, UN POCO PESADO PARA LLEVARLO EN LA CINTURA, TRAE TODO LO NECESARIO PARA LA BICICLETA.

Ben fatto

La verdad es que ocupa poco y parece de calidad. Todavía no lo he probado (por suerte), así que va en su bolsita. El único posible 'pero' es el sistema de enganche de ambas partes. Parece un sistema endeble, de plástico y seguramente la parte más debil de todo el conjunto. Aún así totalmente recomendable

To date there is only one concern I have. The connecting mechanism (that keeps the two halves together) was far more stable when this tool was new. I am concerned that it may become too loose with ongoing use and eventually no longer work effectively. I am glad the storage holster is provided as it ensures this tool will not fall apart from any jostling the tool receives on the trails.
