Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer?

I wouldn't even consider starting to thread a fork from new. I'm also thinking that anybody who would quote a price of $20.00 has probably never done it.
1.hmm good idea. i would imagine a shop probably owns a micrometer to check that first. and i doubt bikeisland is going to have an internally butted steer tube for the price. but i've been wrong before.

2. i thought the shop had to cut off all the threaded portion when resizing my threaded fork, but maybe there were some threads left. i walked out paying 20 bucks, but maybe he hooked me up since i go there a lot. he's the only shop in davis with fork threading stuff so while the procedure isn't common, he dose it enough

The fork dies at most shops are intended only for chasing threads or extending the threaded section on a fork that already has threads. To cut fresh threads on a steer tube you need a piloted die, or better yet a lathe. Take your fork to a machine shop and have them cut the threads (1" x 24tpi) using a lathe.

Threaded forks are thicker than threadless forks so that when metal is removed to make the threads, the fork is still adequately strong.
No, they're not -- assuming a steel steer tube, at least.

Lol.
How is a stem "slower?"
