Do bike shops have specs guides or manuals to know which (eg: integrated headset bearings) parts to use on which bikes? And where do they source said parts (other than from the bike mfr)?
And most importantly: where can the average Joe like myself get this info and buy parts?
The bike I'm currently working on is a 2011 Scott SUB 30, but I can't seem to find any information about specific componentry online. If I were to take it into my LBS I'm sure they'd have no trouble figuring out where to buy, eg, the correct drailleur hanger or headset bearings.
How can I do the same? Important note: I live in Canada, so would prefer not to pay large import taxes from international sources if possible
