You probably think party balloons would stay inflated longer if you tied them off with a double-knot instead of a single. Because if you do, you should bail out now because there’s no point in me trying to explain pneumatic seals or valves or the permeability of butyl rubber. More Important Thingsīefore we go any further, I want to double-check to make sure that none of you readers harbor the idea that the Presta valve cap contributes to preventing air from escaping the inner tube. Less distracted, you probably wouldn’t have bent the bloody valve core in the first place. Before you open up the valve core and hook up the pump, you must first remove an ornamental decoration. On the bike, the only thing Presta valve caps accomplish is slowing down the process of getting air into your tires. If her bike doesn’t have valve caps, that didn’t happen by accident. Her bike was a rolling monument to that man’s obsession with details. Katie F***ing Compton (TM) doesn’t use them! Her mechanic is her husband. Try to find pix of Sven Nijs or Katie Compton racing even the muddiest cyclocross with valve caps. Before you road riders out there say that you need valve caps because you ride in the rain, stop before you embarrass yourself any further. Unlike a Schrader valve (that “fatter” valve-type more commonly found on automobiles and bicycles), a Presta valve doesn’t present an open orifice into which dirt can collect and affect operation. Wait, you say you need to fit the Presta cap to protect the valve? No, you don’t. There, mystery solved! At the time, I withheld that insight to protect one’s self-esteem. Your Presta valves got bent because you carelessly forced the pump on the valve just as you were late for a ride. When you bring your bike to my shop and tell me that your Presta valve cores got bent and you don’t know how they got that way, I know how they got that way. That’s when the cap is off to give the pump or inflator access to the valve. All bent Presta valve cores are due to user error. Sure, the actual Presta valve core mechanism can easily bend, but I’m going to reveal an uncomfortable truth. Once the tube is installed and inflated inside a clincher tire, it can get poked by many things.
It also prevents the valve from damaging the tube casing while folded up before being installed. This plastic cap serves precisely two purposes: it protects the valve mechanism from being damaged. Valve caps are a self-inflicted hindrance.Ī Presta inner tube includes a threaded plastic cap over the valve. I don’t want to trivialize behavioral disorders, but I would appreciate it if you’d check your irrational need for Presta valve caps on your wheels at the door. He is teetering on the edge from dealing with difficult customers as the year comes to a close. note Here’s a Rant: Presta Valve Caps are Stupid from Mark V. I’m truly sorry I let my Comcast and NBCUniversal colleagues down, they are the most talented people in the business and the opportunity to work with them the last 19 years has been a privilege.Ed. “I had an inappropriate relationship with a woman in the company, which I deeply regret. Shell himself acknowledged his situation in a farewell note. He was fired for an “inappropriate relationship” with a female employee, according to a statement from parent company Comcast. Shell was investigated by an outside firm over a sexual misconduct complaint in the workplace. “It does do weird things to your head and you have got to kind of remind yourself that, you know, you put your pants on the same way as everyone else.” It’s very heady being in an industry and being a quote-unquote ‘celebrity,’ whatever that means,” she said. But I think you have to be smart and disciplined and know that unless you tell your supervisor, and unless you’re not a direct report, that having a relationship with a colleague isn’t cool.”Ĭouric allowed that the power of being a C-level executive can sometimes could judgment.
