How to find the Shimano Groupset series for Giant branded bikes
When browsing new and old versions of Giant bikes on their website, they'll show a rear derailleur as Shimano 105 without also specifying if it is from the 5700, 5800 or R7000 series. Is there a way to find out what the exact part number is for a particular bike?

Whatever the current Shimano series is during that year should work most the time.
Number of speeds/model should also help since earlier versions will have fewer "speeds".

Be aware that manufacturers commonly make running changes during a model year, due to cost or availability issues, which is one reason they do not publish specific part numbers. This is often mentioned in the literature as a footnote.

Until you're interested in a specific individual bike does it matter? At that point look at the bike.

The year of manufacture and number of rear cogs will determine which version of 105 derailleur was used on a particular model. The part number will be engraved on the part itself. As long as the derailleur is compatible with the shifter, it will work. As an example, my son bought a new bike last year. It has a 105 5800 rear derailleur, a 105 7000 front derailleur and Ultegra hydraulic brake levers/shifters. Everything works perfectly together as it should. The reason for the Ultegra shifters was that at the time the bike was built, there were no 105 hydraulic brake levers available. The exact components that will work on a particular bike are not set in stone

You have to do the work. There are tons of info out there, just start to compile intro dates, first look reviews, Shimano docs, etc. and build yourself a small data base of the groups you want and the years produced. If you are going back 10/15 years it can't be that tough.
And since a picture is worth a thousand words, get familiar with how the different groups look so you can look at a bike and know it has this or that series.
There is nothing specific to Giant. Manufacturers used stock on hand or ordered; other than for those transition years when one 105 or Ultegra groupset was used and also a possible a later series in the same year.

Okay thank you. I was concerned about compatibility. I was contemplating upgrading parts on different bikes, and having them ready to go and understood before I bought the bike.
