A dog doesn't have a chin, you know?
Is electronic shifting chindogu? What about Biopace?
Electronic shifting is for sure. Then again, it solves the problem of cable breakage in brifters, which IMO are themselves chindogu. (ducking and running..
)
Biopace - I think so. I'm also going to vote for aerobars, unless you are a competitive triathlete or time trialer.
