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.

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.

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

Uso la bicicletta sia per svago sia per recarmi al lavoro. Per farlo percorro 12 km ogni giorno e la foratura o qualche altro imprevisto a volte capitano. Ho acquistato questo oggetto per evitare di avere troppi utensili sparsi nello zainetto e devo dire che è davvero ben fatto. C'è tutto: a partire dalla chiave combinata per smontare le ruote fino alle leve per staccare il copertone passando per l'attrezzo apricatena e i tendi raggi... Top!!!

Ich besitze ausserdem noch das Alien III und das Alien X Für das Alien II spricht: - Maulschlüssel und besserer Schraubenzieher. Dies ist v.a. dann wichtig, wenn das Rad viele Anbauteile, wie Schutzbleche, Gepäckträger etc hat, da diese oft immer noch Sechskant-Muttern oder Schlitzschrauben verwenden. - deutlich weniger rostanfällig als das Alien III Dagegen: - ziemlich schwer, selbst im Vergleich zu den anderen Aliens Bei einem 'nackten' neueren Fahrrad würde ich das Alien X empfehlen, für alle anderen, die nicht groß nachdenken wollen und einfach ein Sorglos-Notfalltool für unterwegs brauchen, ist m.E. das Alien II erste Wahl.
