This for the early 2003 to 05 year model. I believe the part number is TGT0490. I know there are other handles that will fit but would really like to find the original style.
Torium 14 handles from the same period are still available to buy new. The difference between a torium handle is the knob is riveted in situ while trini handles can be disassembled to service two miniature ball bearings.
Aesthetically you cannot tell the difference until the Shimano cap is removed. ;)
