The project to convert the 1976 Raleigh Grand Prix already hit a little speed bump. First, after inflating the tires and taking it for a little spin around the neighborhood, I discovered that the fork is bent, which causes the bike to pull to the left when you take your hands off the bars, much like a car that is out of alignment. No two-arms-up victory salutes on this bike for me (come to think of it, there probably won't be any on my modern carbon fiber road bike either). Nevertheless, I proceeded to strip the parts off and begin the transformation from 70s 10-speed to Twenty First Century retro fixie:
After going through the painstaking process of removing the cottered cranks, I got on the interweb to find out the best way to mount modern cranks on this bike. It turns out that Raleighs of this vintage use their own proprietary 26 TPI thread pattern that makes it very difficult to find replacement bottom brackets, unless I want to shell out about $150 for a Phil Wood BB and specially made Raleigh retaining rings (which I don't). Fortunately, however, the Sheldon Brown website I linked to in the previous post is a virtual cornucopia of information on these old bikes, and I discovered that I can use the old BB with a modern, square tapered spindle. Now the only challenge is to locate the spindle I need.
