Am I the undisputed king of BF....

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Am I the undisputed king of BF....

...when it comes to getting flats in my basement? Man am I ripping through tubes like they are going out of style. In the last week I have had 4 flats in my basement and I will add another one to that that happened 2 miles from home but was caused in my basement. WHat is happening you might ask?

I am ripping the valve stems off with my pump.

I made a post about this after the first time it happened and I thought I got it fixed but now it is happenign even more. I have lubed the chuck on my Silica Pista pump. I now know that I can loosen it's grip on the valve (Right after I got it I thought you just stuck it on and pulled it off, that accounts for 2 valve stems but not the recent flurry). I am sure to pull the chuck off straight so as not to put undue side forces on the valve. I just don't get it...flat after flat and they are all in my basement.

Sorry just had to vent.

No no not on the trainer. I mean I pump my tires before a ride and 4 times in the last week and another 2 times this year when I remove the chuck of the pump I tear the valve stem joint to the tube thus giving me a flat with no way to repair it.

Is there any use for a perfectly good tube with no valve? I have several.

yeh that sucks. had that happen couple times. Maybe you should buy those tubes where the valve stems arent threaded. That should solve it right there.

Save the tubes. You can cut shims out of them for bar mounted accessories, water bottle cages, etc. You can cut a section out of the tube, to make a sleeve for tire levers, mini tools, allen wrenches and other loose items in your seat bag.

Chopper I did it a few times on my fully threaded preta valves... Get one of those busted tubes and try to insert and remove it a bunch of times... This will loosen the little silica washer inside... The partially threaded ones worked for me too...

When trying to remove the pump head, hold the valve and a couple of twists on the side should work...

Maybe that's what I'm doing wrong. My front tire, man if I look at it wrong it drops 20 psi. Back tire - fine.

I bought a Silica Pista pump a couple of years ago and gave up on it. I didn't rip valves off, but it was a complete pain in the arse to use. Maybe if I had been patient it would have eventually broken in. Maybe I'll try it again some day when I'm feeling adventurous.

You have several options, one is buy a new pump or you could buy a presta valve adapter for a buck at the lbs and use a regular pump.
