I am trying to get an online reference to the exact specs of my second hand bike. What are a) Some good techniques/things to look for? b) Some resources to help the dating process.
E.g I see that https://bikepedia.com/QuickBike/BikeSpecs.aspx?item=24141 visually exactly matches my bike, however the later models are closer in terms of exact specs, but none are an exact match.
I want to find out for examples which models of tiagra RD were 9 speed (which mine is) but I dont know of any good place to find such information. (This hobby seems to be all about latest/greatest :( )
Alternately I want to find out where to find/locate the model numbers of the various components. Other clues I have is a Truvativ crankset 53/39. FD RD and shifters all tiagra.
