Presta valves

ok, this may sound like a dumd question but, when you inflate a presta tube, do you screw the little thing that realeses the air up orleave it where it is. also, should you expect to make any quick progress with a mini pump.

1. unscrew
2. inflate
3. screw

Mini pumps do take some tume. Crank Brothers makes a nice compact model with two modes; 1) high volume and 2) high pressure. You use the former first and then the latter to obtain max pressure. Floor pumps are the only real option unless you're stuck on the side of the road.

thanks a lot. i have that pump so i will be sure to use that technique.

yep, screw it back up after use.

take a look at the Cyclaire pump - its sort of half way between a track pump and a carry pump. Its just won some awards here in the UK and seems to do a good job.
