Bike Accessories

These work just fine. I dont know why some people have trouble with them. Thread on, put in air with my compressor, remove and stick in my pocket. Seems easy to me.

There is absolutely nothing more irritating about being out on a bike than discovering that you need to pump up one of the tires, and only then discovering that this bike's tubes have the wrong kind of connection for the air hose at the gas station. That's where these come in. Yes, the *process* remains annoying; you have to remove this adapter, unscrew the little nut to free up the valve core, pop it a bit to make sure it's not stuck, reinstall the adapter, air up the tire, remove the adapter, retighten the *&^% nut, and then put the adapter back on so that you've still got it next time. Life would have been so much easier if the bike's manufacturer had just used wheels that accepted Schrader valves? Right? But they didn't. So you need these. And with half a dozen, if somebody makes off with one of yours because *they* forgot to bring one, you won't be out of luck yourself.

Bought those to use an air compressor at a gas station to fit my road tubeless tire. Attach it on the French valve and hold it by hand while sending air, installation done in 5 secs!! Much cheaper than buying expensive inflator pump or CO2.

Pumped up my bike tire with this attachment.

I have Trek bicycle and it has always had these stupid skinny air valve that nothin will fill. These handy dandy little things work to convert them to standard bicycle pump tire valve size.Thank God because whos bright idea was it to re-invent the bicycle tire valve?These solve the problem and do it well.VERY HAPPY
