Fits oversized (31.8mm) bars
This one: http://www.extralite.com/Products/roadstem%20OC.htm
1. it is missing one of the stem clamp bolts as the allen key holes had been chewed up by previous owner (which he failed to tell me about!), so bolt had to be ditched. However, the good news is a standard stem bolt fits, so you don't need any special Extralite bolt.
2. It has a small surface scratch (about 3mm long) on one side - as shown in photos. Purely cosmetic damage.
I know it's not retro, but it is a beautiful piece of CNC-kit and I'd rather sell it here
