I've noted that the "bike people" seem to more or less obsessed with the names and niceities that go along with pedal power.
Maybe I'm "a bit" biased, but I have same feeling. Sure there's whole bunch of high prices due "right name" in skiing or any other sport, but I have feeling that either marketing and PR is super good in cycling or users are just a little bit easier to fool. You can literally sell shit for price of gold as long as you start new trend that with this shit you get extra 0.01W
But then again, maybe alpine skiing is a bit specific, as in my mind it's the only sport where you actually perform worse with top end gear that you are not capable of use, then with lower end gear that fits your capabilities. With cycling for example, you can ride as good with real pro tour bike as you would with ($5000 cheaper) bike fitting your abilities. You won't gain those few % out of that real race bike, but you won't be any worse becase of it. With skiing, you will actually ski worse with FIS DH skis, then you would with recreational skis, if you are not able to ski on race level.
Anyway a bit more on topic... I'm sick of my presta adapter that I need to put/screw on presta valve to use air compressor (with shreder head) to fill my mtb tires. It's great tool to have with me in case I get flat and co2 bomb is not enough and gas station with air compressor is somewhere near, but for home, I would want some decent head that would fit straight to presta valve without any adapters. Any suggestions for that, and regardless on this thread, not something for 30, 40 or even $180... yeah I have seen super cool (beats me what is so super cool to be worth so much) presta heads for $180.
