What to look for when replacing a Fork?
I'm interested in replacing a 1" threaded fork with one I saw on ebay. I haven't taken my bike apart to get specific measurements but it seems like the ebay fork is slightly longer than the one I have right now. My question is do I have to get exact matching measurements?
or is there a range that I can play with?
If I need to get it cut down to size, what does your LBS charge?
What other measurements, geometry or parts do I have to consider?
other info: I have a quill stem. The reason for replacement is only for appearance, the green fork on my red bike looks like I'm celebrating Christmas year round, though probably deter some thieves...
