I need a longer stem, I am interested in one from nashbar that is for 1 inch threaded forks. How do I know if I have a 1" threaded fork? It is also for a 26.0 bar clamp. Is that the measurement of the diameter of my bars where they attach to the stem? Here is a pic of the stem area of my bike
The bike is an early to mid 90's Miyata 714.
