Identifying Parts and Manufacturers
IS there an easy way to identify part #'s and manufacturers by the info stamped on them? For example, I just bought a crank arm from my LBS but failed to find out any info about it (it didn't come bagged or anything, and I forgot to ask before I walked out). IS there a series of stamped codes that I could find out about. I just paid $15 for this crank arm but know nothing about it. Yes, I could just ask the LBS next time, or even go back this time, but what about the parts on my current bike that I got used, or the other parts bikes I salvage from the roadside?
