For years, I'd tried every tool I had to stop the chainring nuts from slipping when tightening, but nothing worked. This tool does the job and is cheap. If you don't have one, pick one up before you need it.
This is a solid tool with most everything needed. Manufacturer says the tool weighs 136 gram (this site says .3lb which is the same). Actual tool weighs 179 grams which is a big miss on published weight. Big deal? Maybe not, but I bought this for bikepacking racing where little stuff like this adds up. A little disappointed in the misleading specs.
Park Tool has been making quality tools for a long time. I need this bottom bracket tool in my collection because I'm changing my cranksets several times a year. I have a front double, single and triple I switch in and out for mountain biking, cyclocrossgravel and road style riding. If you like to work on your own bike instead of taking it to your LBS, then this bottom bracket tool pays for itself in probably one use. You can count on the quality of Park Tools.
i am trying to start up a bike detailing business and i thought this would be a big help. it is more than a big help!!! it is a bit on the heavy side but who doesn't need a little upper body work! i like the way it folds down quite compact for transporting and easily stores in a corner of my bike room. the pcs-10 upgraded clamp is by far worth the upgrade in price. the stand holds any bike with ease and with confidence that it will not hop off. the build of the stand is the usual park tool high quality. i looked high and low for a better price but westernbikeworks.com always comes through with the best price, quality customer service and secure rapid shipping.
