L, it's TSL.

No. I acquired mine as a frameset only. It's original owner had parted it out on Fleabay before selling the frameset locally. Which is fine by me since I'm a Shimano guy and it was all Campy.

EDIT: I checked teh Googles real quick for ti stem +quill and found several references that seem current, if a non-original yet still Ti quill stem will work for you.

Then you'd better get rid of those wheels and levers too! I know. Just send them to me.
