Aluminum fork with steel frame
I have an old Raleigh that is built up as a single speed. It has a 1" threaded fork and I had to replace the headset. There is only enough steerer length to allow for 31mm of stack height which is too short for most modern headsets (I know...Chris King is short but they are pretty expensive too). I found an aluminum fork that is NOS and plan on using that. It has the right length steertube to allow for about 41mm of stack. Here the questions:
This fork is bare aluminum. I could polish it but it would eventually oxidize again. I was thinking about a couple of coats of black laquer followed by a couple of coats of clear...then buff out. Other suggestions?
Any concerns with an aluminum fork in general? I know that aluminum doesn't have infinite fatigue life. When should I start being concerned? Should I just ride it and inspect periodically for cracks? Or not worry at all?
Thanks in advance,
