Only $500 Per Gear

There's a very nice 1946 Olmo on eBay right now ... equipped with the rare Cambio Corsa rod-shifter. 

Bidding is at $2,000 as of this blog post, which works out to $500 for each of the four speeds you'll have access to.

If you've ever wanted a Cambio Corsa-eqiupped bicycle, this one is worth a look.
