Is anyone familiar with this product? It's a mounted cable splitter that allows dual shifting from either the STI or aero bars. It has to be mounted on the downtube boss where the downtub shifters would be.

I was thinking of playing with this on my TCR, but tha bike doesn't come with a downtube boss. I know Team ONCE ran a downtube shifter for the front derailler on the hill climb stages of the TDF (Lance did the same on his Trek), so I assume that there must be some sort of a clamp-on downtube boss available for the newer bikes that don't have these.

Has anyone tried the Profile STI adapter? Anyone know where/if a clamp-on downtube boss could be found? Here's what it is http://www.profile-design.com/...ters_stiadapter.html
