So, I bought me a single speed for $100 today. It's a raleigh super grand prix. The guy simply threaded a bmx freewheel onto the rear wheel so my chainline is a good bit off. I'm pretty happy with it though. Steel lugged, 700c rims, english threaded bb and somewhat horizontal dropouts. A bit more than I wanted to spend but it's got what I want and I have it now so I don't have to look anymore so I'm happy. I'm pretty stoked because it had bar-end shifters too, so there aren't any braze-on's on the downtube.
Now for the questions...
It's made in England and says TI-Raleigh 20-30 hi-tensile on the seat tube. Now from what I know hi-tensile is crappier than chromoly. Is this correct or is there something I'm missing?
What's a good gearing? I was told a ratio between 2.2 and 2.8 is good. Currently it's a 42/16, which makes it about a 2.6. Does all this sound about right?
Also, what's a good thick tire. I don't really care about weight or anything really besides flat resistance and long life? This bike is going to be pretty much, strictly a commuter. I heard maxxis fuse, or re-fuses are good?
Should I go with a regular SS, or make it a coaster brake single speed with no brakes, or just go fixed? I was leaning towards the coaster brake option. I read on hear that bendix (I think that was it) hubs were good for that. Or is one of the other options just that much better that I should really go with it?
how do you measure the chainline?
other than that, I'm totally open to any tips or tricks you guys would like to offer.
I think that's it for now. Also, I did some light searching but couldn't find too much in the way of these questions so I apologize if they've been asked a million times already. I couldn't find the answer.
Thanks for the info.
