So I was getting ready this morning, got dressed, etc. First commute on the new bike, yay!
Decided to check the tire pressure, unscrew the cap and loosened the presta valve. This is my first time filling up a presta, luckily my pump have a double "mouth". So I plugged it in the presta opening, lock the lever, saw the pressure is 80, then I pump away until it's around 110.
I then unlock the lever, checked twice, I'm 100% sure it's unlocked. Tried to pull it out, it didn't budge a bit. I checked again, making sure that the lever is all the way out to the unlocked position. Still stuck like it is glued.
And I decided to put some elbow grease into it, pull it out with a little force. Then WTF? A loud PSSSSSHHHHH and the valve went limp. I knew than I was royally ****ed because my spare tube is still on it's way from performance. I tried to pump but it wouldn't hold any air, took off the tire and saw the valve was ripped clean off the tube.
So I took the bus this morning.
Anyone know what I did wrong? Did I miss a step? Recap:
Loosen the small thingie on top of the valve
Pushed the pump head all the way in
Or do I have a defective pump?
