After one year and change these levers still get the job done. They have rescued many a stubborn tire from damage and make replacing tires easy. Leave the blue, black and coated metal levers on the rack at your LBS and get these. One exception would be those of forged aluminum from the company that starts with an L. The price is right and they do not gouge my seat bags. Good design at a reasonable price.
More than a year later this pump is working fine, The dual pressure mode makes it a snap. For those that find it tedious to hold a pump on a presta stem and inflate a tire look for a pump with a hose connecter - myself included these days.The rubber seal on the pump head sheds a slight bit on the valve threads but should last a couple more years before replacement is needed. A very good light pump for your seat bag.
Used this tool for over a year gave it chance to prove itself. Operating the chain tool with wrench on the separate tire tool was not a good experience. Not well thought out in my opinion Crank Bros does it better and so does Blackburn. The plastic portion of the tire tool eventually broke and my tires are not that tight on the rim. An 8-10 mm wrench instead of a tire tool would be good. One should use separate tire tools anyway. The pop-on 8mm Allen wrench is ridiculous. Expected a mature product from Park this one is a failing sophomore effort.
Small version which takes a little more time to operate fits into a 1 liter seat bag suitable for rides (shrader valves) with the grand kids. The medium version is frame mounted for commuting and adult rides. Both do their job very well. Holding and operating a pump on a presta stem has its drawbacks. The connection hose has answered the need for these old hands. Works great every time and the pressure relief for presta valves is an added bonus. Well designed product for the price and if you can find a sale all the better.
