I got these for my track bike, but once fitted they were to big for me.
These are the one piece aluminum stem, base, aerobar setup here. Size large.

I have all the original included items, pads have been installed, but there is literally 1 mile of use on them.
I paid $120, would like to get $80 shipped.
