AWESOME TOOL TO HAVE IN YOUR BIKE TOOL REGIMENT! I got started with bike tools with this one. After getting fed up with what Bike shops charge @ $60/hr and only installing what they sell, "overpriced bike parts that pricepoint sells tens of dollars cheaper," I decided to buy this tool to replace my rear cassette that work out years ago. I got it along with a chain whip tool that the Pricepoint rep advised me to buy and when I realized how much I could save buying the parts from Pricepoint and installing them myself with the right tools over the bike shops labor fees, I was sold on owning my own bike shop mechanic's tools! The money you'll save in the long run is worth it. Not to mention, you become a bike mechanic eventually. Which does have a down side. All your buddies will be coming to you to install their pricepoint parts for free. But you can swindle some free beers out of it so it works out pretty good! ;) Seriously, nothing takes the place of having good bike shop tools! I started off on a cheap walmart bike 19 years ago and now I ride a pricey DH bike and built a duplicate bike on my own from frame up with all the tools I bought from price point and the knowledge on fixing bikes you can get right here on the internet from other bike mechanics willing to help you out. I now consider myself a bike mechanic. With the right tools and a little knowledge that most biker will be glad to give you, you can save tons of dough by owning your own bike tools. This one got me started. It's durable, and will last you your life time. All you need is a large rachet to turn it. Or a wrench on the squared off end if you don't have one. Combine it with a price point chain whip and you're off to becoming your own bike fixer.
