Help - Tire Pressure / Floor Pump Issue

[Dubz]

@Oakleaf - Thanks for your advice.

Everyone else: I managed to resolve this issue after going to my LBS and getting them to check my pump and training tire.

Here's a video from Terry Bicycles which is really useful.

And my very own step-by-step guide for anyone who's new to using floor pumps with Presta Valves!

- Move your wheel so that the Presta Valve is at 6 O'Clock (some people prefer 12 O'Clock, but for the Bontrager Recharger Track Pump 6 O'Clock is easier).
- Remove the black cap. If you lose the black cap, don't worry. It's only for aesthetics.
- Don't worry about the silver cylinder thing threaded on the valve. Apparently it's not majorly important.
- Unscrew the little knob at the top of the valve as far as it can go (it isn't removable).
- Press the top of the knob inwards to make sure it's not stuck. If there's air in the tire, it'll release a bit of air.
- Place the head of the pump with the bigger hole on top of the knob (on the Bontrager Recharger Track Pump this is the grey head).
- On the Bontrager Recharger Track Pump, the black head with the smaller hole is for Schrader Valves.
- Press down so that the head of the pump is fitted on.
- Lock the lever in place (on the Bontrager Recharger Track Pump the black lever will be pointing upwards).
- If the head of the pump or the lock is not on properly, or the valve is bent, air will leak or not go into the tire.
- The pressure gauge on the Bontrager Recharger Track Pump will read 0 PSI, even if there's air in the pump.
- Pump using just 1 foot on the floor pump (this works best on the Bontrager Recharger Track Pump).
- Give about 2 or 3 pumps and the needle will move to show what the current pressure is in the tire e.g 20 PSI.
- I found that at about 80 PSI it seemed like the pump wouldn't work any more and that the tire was full, even though I needed to pump up to 110 PSI.
- In this case, keep pumping to where you need to be. It's just that the resistance is harder as the tire becomes fuller.
- Then pump about 2 or 3 times more. This is to replace the air you will lose when closing the valve.
- Unlock the lever. Quickly pull off the head of the pump and screw the knob back as far as it can be screwed to minimise air loss.
- Don't push the knob in this time or you will lose air.
- Replace the black cap and you're good to go.
