It is a nice tool set, include all the allen wrenches you needed to adjust bike handle, brake and brake handle, speed rover, seat position.
It also include the chain tool for remove a section of the chain. In addition, it has two size spoke wrench for ajusting the wheel.

When you ride your bicycle, your tires may rub against the brakes. This is easy to fix wheel problem - spokes need adjusting. What you need to do is wheel truing.

Place bicycle upside down. Spin the wheel while holding a pice of chalk close enough to the wheel. After spun around a few times, stop the wheel and take a look those chalk marks. Do this process on the other side of the wheel. Tighten the spokes on the other side of the chalk mark and loosen the spoken facing the chalk mark. Adjust each spoke one turn.
Wipe out that chalk mark. Once all the chalk marks are gone, you can spin the wheels and using chalk to find the next spot to tighten and loose the spoke. At the end, you have a perfect round wheels :-)

The included spoke wrench has two sizes. It works fine for all our bikes.

I used this tool assembled a complete tandom bike in two hours. The tool felt little loose at the end of the assembly. But nothing really worn out. 5 stars

every bike should have one of these in its saddle bag. i have the original alien and have always found what i needed to do any work on my bike. both on the road and at home. it is very well thought out. 5 stars

Pretty much every tool you will need in a compact case. Tool seams solidly built except for maybe the plastic parts, but you have to shave weight somewhere. It is not the same as having all the tools seperate. Don't plan on using it for routine maintenance, just for emergency repairs/adjustments. Ergonimacally it can be a little awkward to use, but it gets the job done. I used cable ties to mount mine to the seat post, as low as it will go. If it gets lost or stolen, I will replace it with the same model. It is worth the $$ just for the peace of mind knowing that you have pretty much whatever tool you may need. 4 stars

Excellent is all i was expecting...very well made good material very strong... I have had to use it once but it had every thing i need... the chain tool is excellent 5 stars

I got this for the chain tool. It works as well as a non-portable tool. For me, the other tools are just a bonus.

I would agree it has everything a "swiss-army" bike tool should have, including tire levers, spoke wrenches, a knife blade, and bottle opener. The halves separate and lock together easily.

Several of the tools lock open, and the knife also locks closes to absolutely prevent accidents. An interesting feature of the case - it has a spring loaded belt clip for easy attachment to a pack or your waist. It also apparently has available accessory mating clips for quick release attachment to seat post or handle bar stem.

I would like to have compared the blackburn tools,Blackburn Toolmanator Multi-Function Bike Tool & Blackburn Toolmanator II Multi-Function Bike Tool but the bike mechanic I spoke with agreed this would do fine. 4 stars
