All the tools you need on this planet.

Topeak's Alien tools have long been favored (and copied) for their ingenious and ergonomic pull-apart design and well thought-out tool assortments. The Alien II has 26 total tools, making it the most comprehensive multi-tool in the Alien line. Like all Aliens, the II splits in two for ease of use. If you're comparing it to the very similar 25-tool Alien III, the differences we notice are that the II includes a miniature 15mm pedal wrench, whereas the III does not, as well as 2 tire levers that are integrated into the tool body, whereas the III has just one tire lever. and it doesn't have spoke wrenches for Mavic and Shimano wheelsets, while the III does 

So if you don't ride a Mavic or Shimano wheelset with brand-specific spokes, the Alien II should have everything you'll need for trail or roadside repairs. A pressed stainless steel frame with engineering-grade plastic provides the strength needed in a lightweight design. The tool bits are made from chromoly steel for a precise and durable tool. The Alien II is also equipped with a chain tool that's compatible with all singlespeeds, and most multi-speed chains — including 10-speed chains. The Alien II also comes with a chain hook to assist with chain repairs. 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. 

The Topeak Alien II Multi Tool comes with a compartment for two chain pins and a nylon bag to protect the Alien in a pack.

Must Have

  • Familiarity: I've used it several times

All in 1 go to muti tool for the days out on the bike. Would recommend all the tinkerers have one on there person if trail side maintenance is your guilty pleasure.

The Alien is the original all-in-one

  • Familiarity: I've put it through the wringer

I've had one of these for years now. I wish I could justify buying more but the first one is just perfect! Has you covered for just about anything you can encounter on a ride. Sometimes not even bike related.

Big Things Come in Small Packages

  • Familiarity: I've used it once or twice and have initial impressions

This is a perfect tool for handling just about any minor repair on the go. Comes with a nice little velcro carrying pouch, and is easy to attach on the outside of your commuter pack for quick access. Sturdy as hell and must have for any commute to work.

Sturdy tool for just about everything

  • Familiarity: I've used it once or twice and have initial impressions

The Alien 2 is a great tool that covers just about everything you'd need for a quick tune. The tool splits into two halves and reveals a detachable mini-wrench and the mechanism that allows you to release the knife-lock.

Everything is of high quality and is very sturdy. I have confidence that I'll be able to make most of the repairs and tweaks that arise using this.

I purchased a full-sized pedal wrench from here for extra leverage on the 15 mm components. It also comes with a Velcro-closure carrying pouch that isn't pictured, but it's a good way to store or carry the tool around and will do a great job.
