Cheers, Muirenn.

I actually have a pressure gauge on my pump. I got the same one that my LBS uses (Bontrager Recharger Track Pump). They recommended it. When I connect the pump, the current pressure doesn't show. The gauge says zero. It's only when I pump that the needle moves up. This is why I'm confused.

Also, noob question here: what are valve caps on the stem and washer nuts?! I'm seriously technically deficient when it comes to biking. I'm trying to learn though. I've learned so much in the past few months since I first decided to buy a bike.

I thought the stem was the bit the handlebars attach onto because when I got my bike my LBS said that they switched around the stem to give me a more comfortable reach. I'm 5' 3" but prefer the unisex model of the bike I got versus the WSD. With the WSD, my arms felt wrong - like they were too bent. With the unisex model, I felt like my reach was too far until the LBS switched around the stem. Then it felt fine.

On my wheel, I only have a black cap which I take off the Presta valve. There's no other cap. I had to unscrew the silver round thingy to loosen it. I pushed in the silver round thingy in slightly to make some air come out and then fixed on the floor pump to the narrower hole (my pump can do Schrader valves too so it has a wider hole as well) and locked it in place. Then I pumped.
