I think the poster's probably referring to the crazy old school Cinelli teardrop bars (and the lookalikes)...for those you just gotta patrol the **** out of eBay, hit up the vintage bike shops, pick through the trash and hope to god a pair of them turn up for less than 200 beans.

...orrr go for the B123's. Businesscycles.com has them down to 36cm. Realistically, anything skinnier than that on the street is unfunctional anyway.
