How do I identify an SR SunTour fork exact model? I recently located this SR SunTour service manual, containing schematics of a load of forks. Trouble is, my fork only has "XCR" on a sticker, and production date stamped.

At some forum this is discussed and links are provided to SunTour's XCM, XCR and XCR product lines. Strangely, my XCR does not match visually any of the presented (mine has no V-brake option).

Am I supposed to find a model number stamped somewhere on the fork, as with most other bicycle components, or should I deduce which fork it is from the features e.g. wheel size, brake options, outlook, locking and adjustment mechanisms.

I would be quite surprised if the model is not stamped. How do bicycle mechanics deduce the model - do they know them all from experience?
The fork should have a serial number. Not obvious and a little small and faint, something like tb0111xxxx. Mine was located on the lower assembly.

Go to https://www.srsuntour-cycling.com/service/ enter the number and it should come back with model type and year of manufacture. From that you should be able to find the exploded view pdf.
