    Bottom Line:I have used this tool for years with no problems - folds up nicely and fits into small spaces - has all the common needs -I left it in the car once and had to borrow a no-name tool to adjust my seatpost and it snapped right off. If i ever lost this I would buy another that same day

    Favorite Trail:Any that will prolly cause me to face plant hard
    Duration Product Used:More than 3 years
    Price Paid: $40.00
    Purchased At:BikeUSA
    Strengths:Has almost everything you need for the trail, including a pair of tire levers! Sturdy nylon pouch with fixer-thingy-attachy-point. Splits into two pieces for easier handling or using two tools simultaneously.
    Weaknesses:Bulky, square turd fits awkwardly in my seat wedge. The fixer-thingy-attachy-point adds additional bulk to pouch. If you wanted to mount the pouch on the bike directly (which I wouldn't do because its just one thing to fly off in mad crash) you have buy the bracket (2 styles-stem or bar/post) separately. Doesn't include pliers.
    Similar Products Used:None
    Bike Setup:Custom '08 S-Works Stumpy, Crank Bros Cobalt XC rims.
    Bottom Line:I've had this now for 8 years and its been both my trail-side tool that has gotten me out of all the jams I've been in, as well as a general purpose garage tool supplementing my auto tools when performing bike maintenance and repairs.

    Besides the bulkiness, the only lament I have is that it doesn't come with a plier tool and I was contemplating carrying a compact Leatherman for that purpose (more weight and bulk). But I guess Topeak has listened to customers and their new Alien DX Multi-Tool comes with a plier for pulling on cables during trailside repairs!

    The Alien II can be had online now for roughly $25. The new Alien DX for $39.

    Overall, if price and not having a plier along is more better for you, I would definitely recommend the Alien/II.

    Otherwise, my choice would be the new Alien DX (which I will review when I finally receive it and put it to use).

    At $25, the best value for what it does! Dropped a hot poop for missing a handy all-purpose plier tool.

    the kit is modular, you can split ti in to 2 pices for more clerance and easy handelling.
    Weaknesses:abit havy (but i dont mind it)
    Bottom Line:when i go for aride i like to be prepared for anything, this tool give me confidence cose it's got all the tools inside.
    saved me more then one time (helped me convert to a singlespeed when my rear druiler got yanked out taking with him 3 spokes from the rear wheel. 50 miles from no where...)
    if you ride xc you can sattrl for a smaller toolkit but if you go on long rides in hard terrains you need to be prpeard for enything...dont think twice...it's alife saver!

    Purchased At:gift
    Strengths:Solidly built. Tons of tools
    Weaknesses:bulky and heavy
    Similar Products Used:various cheap multi-tools
    Bike Setup:trek fuel 98
    trek XO 1
    Specialized Stumpjumper (SS converted)
    trek 1000
    Bottom Line:I think I have had this tool for close to 10 years. I got it as a gift shortly after they first came out with them. I may have gotten it x-mas of 1998. It has gotten tons of use of the years and still performs better than any other multi tool i've used. A small piece broke off the body of mine that makes the two tools no longer clip together, but everything else has been wonderful.

    I don't there is a tool on it that I haven't used many times. Sometimes for rides or races I take it out of its case and put 1 tool in my right jersey pocket and the other in my left. Just to keep the bulkiness a little less.

    Duration Product Used:More than 3 years
    Price Paid: $30.00
    Purchased At:Niphuis
    Strengths:The thing has the exact amount of tools. I am a recumbent biker and it's equally fair with recumbents as well. There are not too many tools in the Alien, but all the possible nuts and screws have been considered before it was issued.
    I don't fail on any; perhaps a canopener like the Swiss Wenger or Victorinox could do.
    At this moment of writing the review I am considering to buy the DX. Strong would be a good wire cutter, but I read a review that that particular tool is not functioning properly.
    Weaknesses:you can loose it.
    Perhaps the plastic parts might have been given a bit more stiffness. For my tight 20"tyres, they bend a bit to much.
    Perhaps the people of Topeak thought about the cranktool it to be used with some aditional help. I am not going to be negative on it but it may be a weak thing to use in practice: my cranks are just too tight with my pedals that I can open the thing.
    Similar Products Used:I tried to get a tool with equal consideration for the needs of the bike but did not find any.
    Bike Setup:Challenge Hurricane; Rohloff Speedhub; Son; Shimano XTR Discbrakes; some Rockshock damper.
    Bottom Line:The tools I have with me during travelling include a Leatherman Crunch, a Buck Whittaker and this Topeak Alien.
    I still try to find some good and most lightweight combination of tools but this Topeak Alien is most efficient. Perhaps an improvement on a reliable cable cutter would make sense?

    Purchased At:Halfords
    Strengths:Compact, great range of functions, sturdy and heavy enough to notice when you've not got it with you.
    Weaknesses:It's heavy, no Torx heads, some tools don't "lock" so get a bit wobbly under load.
    Similar Products Used:Plenty of no-name multi-tools and various individual items
    Bike Setup:Trek Fuel EX8, Giant XTC850, Giant TCR Team
    Bottom Line:I've had this for nearly 5 yeas now and never leave home (on the bike) without it. Small enough to fit in a saddle pack on a road bike and comes with all the tools you're likely to need on the road/trail. A tough nylon pouch keeps sharp edges and loose tools in place, but an elastic band does the same job and it's lighter. Not the cheapest, but I've not found anything else that comes close.

    Bottom Line:This is the best tool I've ever used! While it's a little heavy, it works better than every other cheap multi-tool i've ever seen. This includes other Topeak products. I would recommend this to anyone. The only thing that would be better is if it were lighter, but then that would compromise quality.

You can practicaly put together a bike with this thing. I got it for $11 but the regular price was about $30. A little pricy but well worth it. It's probably one of the better tools Topeak has made.

    Strengths:compact, multi-functional, strong, light weight for its size and tool selection.
    Weaknesses:none found
    Similar Products Used:assorted tools, too many to carry on a trail.
    Bike Setup:04' Specialized RockHopper Comp.
    Bottom Line:An excellent tool in design, and build. Compact, lightweight, multi-functional, a "swiss army knife" of tools. I carry my Topeak Alien II whenever I ride. Agreed, it can not replace a good selection of "shop" quality tools,(for bike repair and regular maintenance) but for its intended purpose and functionality, it can't be beat. To date not only have I made minor adjustments on my bike on the trail, but I have also made emergency repairs on others bikes when their tools were un-able to do the job or left behind. It is a little pricey, but for what one gets and the peace of mind it gives, (knowing it is in my seat bag), it is definitely worth every penny spent.

    Date Reviewed: June 2, 2004
    Duration Product Used:1 Year
    Strengths:Compact, Well Made,
    Weaknesses:Built in Tyre levers may break easily. Torx bit and Pedal wrench keep falling off. Steel may be of an average grade.
    Similar Products Used:None
    Bottom Line:While This tool will not replace quality workshop tools it is exceptional for its intended purpose. Having said that I HAVE used it to totally strip down my bike on a few occasions and all tools have held up exceptionally well. The pedal wrench is awkward to use but many pedals I know of have hex key recesses accessable from the inside of the crank arm anyway.
    The steel used for the Hex Keys and wrenches seems a fraction soft. Make sure hex keys are fitted properley and the philips head screwdriver fits the screw head properley to avoid rounding the tools.
    The torx bit can be annoying the way it drops out when the pedal wrench is removed but all in all the positives outweigh the negatives. I keep mine in my pocket while riding and forget its even there so weight is not a real problem.
    Bottom Line...If you are looking for a good Multi tool that will last years with a little care and will get you out of a jam, then the Alien is that tool.
    In hindsight I would buy this product again.

Just get yourself a multi-tool with the hex wrenches and screw driver, and a seperate Park Tool chain tool. Topeak does though make nice high grade steal multi-tools and you can usually find them at TJ Maxx for very cheap.
