In case you haven't seen the current issue of the French mag Velo there's an article in it showing Shimano's new pneumatic derailleur. Shimano has adopted their Airlines downhill system for road use. The bike is a Gitane time trial bike belonging to Bradley McGee of La Francaise de Jeux.

The system is powered by an airtank built into the aerodynamic downtube of the bike. It's hard to imagine the benefits of this system. Possibly some weight savings (plastic hoses being lighter than steel cable and housing) and the elimination of cable stretch. Still it seems needlessly complex.

Yeah, I'm going to feel way in adequate next time I show for a ride with the boys and they're all sporting pneumatic derailuers and I've just got a crappy cable system. ;-)

Have you checked out the price on the Airlines system for DH bikes - something like $1,600! Just 'cause something can be done, doesn't mean it should be done. Now, if I could only get my dog to stop embarassing me in public when he licks himself....

I totally agree. It seems like the andwer to the question nobody asked! Still it is interesting to see what they'll roll out.
