I work near there and went in a while ago to try to find some vintage hubs. They didn't have what I wanted but rummaged around for ages looking and seemed to have plenty of stuff. Very helpful
Used the velibs in Nantes in France recently. Worked well, jumping on and off for short journeys. And credit card statement has just come up with 83p for the day. Bargain!
I built a bike based on an old Saracen frame and within days my girlfriend had adopted it and still uses it. Maybe Saracens have this effect?
