Wow! Something nearly moved in my pants when I saw that Pug
What a cool Bridgestone, a small wheeled road frame with road calipers and even takes a 53 front ring. It's like the planets aligned for your needs.
Your going to love those tires I can imagine them fitted now. I never bothered with the 1.4 version after riding them only once.
With the 1.1's you'll need a smaller tube to suit, the smallest I could find went down to 1.25, they'll work then pump them up hard to seat the bead straight, there tight first fitting them.
This bikes going to look the biz when finished, cant wait.
