Alien II Multi Tool

The Topeak Alien II multi-tool is pretty incredible. It’s an entire tool box that fits comfortably into your hydration pack or jersey pocket. There are 26 tools in all, and short of a cracked frame or complete fork overhaul, you should be able to fix just about anything with the Alien II.

The Topeak Alien II combines pressed stainless steel with engineering-grade plastic for lightweight durability. It also splits apart for ease of use. The Alien II comes with a chain tool and a chain hook to assist with chain repairs. It also comes with a 15mm pedal wrench and two tire levers. 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 Alien is the original all-in-one

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

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

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.
