Ride enough, and sooner or later, your derailleur hanger will become misaligned. And when it does, shifting suffers. You could take your bike to the shop and pay a mechanic $35+ to realign it, or you can pick up this tool and do it yourself in a matter of minutes. It's simple to use, and Park Tool has a great You Tube video that shows you how to do it right. Two realignments and the tool has paid for itself. Like all Park Tools, this alignment gauge is well made and will last. It's a solid investment for anyone who enjoys working on their own bikes
There's not much to say about this item. As can be seen in the pic, it's a solid piece of metal with six tools along the edges. Does an effective job at basic roadside repairs, although you won't have every size allen bolt you need, particularly if you're on the road with your kids and their bikes along with your own. Also the length of the item can get in the way of screwing or unscrewing a bolt - meaning you might only be able to turn the bolt 20 degrees at a time. That being said it's a quality, reliable, simple tool and I expect it will last a lifetime.
After years of struggling with bike maintenance, this stand makes it so much easier and even a little enjoyable. It is easy to put together, use and is heavy duty, worthy of the Park Tool name. The 10.2 is solid and effortlessly supports my 35 lb all mountain bike with a surprisingly intuitive clamp and adjuster. If you are looking for a lightweight or portable stand, look elsewhere! While is folds, it is bulky, heavy, and really only meant for temporary storage. This stand is best suited for daily use and benefits from being assembled and left intact.
