And you'll have to put another whopping kilo on the left side to keep your ccb (CoolCarbonBike) from
tipping over ;-)
WELL, perhaps a "Ti" Chain might be a tad lighter for you. http://www.vikinginternational.com/
However they don't have them for a 9 speed setup, as of yet. EZ Biker Pompano Beach, Fl. (GRR
Ti, Tailwind and SOON, Bacchetta Aero Pilot)

Well they would certainly lighten my wallet at 225 usd a chain. I'm not that far gone yet,
luckily. ;-)
If I really get the urge to lighten the chain I will buy the new hollow-pin SRAM chains. 200 g
saving at best, but at least the price was a bit more reasonable.

Mikael Sure makes a good case for a FWD system. Anxiously awaiting my Polish Lowracer also!
Brings to mind the notched belt drive, but I have no idea how well it would work on a long chain
run. I keep thinking that on a recumbent the chain should run INSIDE the frame tubes but I suspect
that idler problems would prevent this.

Look at BentRider Online's Interbike 2002 coverage (still on the STP section, I think). Theres'a
delta trike that uses a kevlar belt for part of the drivetrain. The problem is, you can't use
derailleurs on a flat belt.

Have a look at this one: http://legslarry.crosswinds.net/misc/Pix5.htm - Clemens Bucher's bike on
the left. Main frame member is carbon-fibre, with the chain running inside it. Mid-drive is a 3x7
located inside the frame under the seat. Final drive runs down the left side of the bike, inside the
single-sided hollow aluminium swing-arm. It's a bit heavy, but as a commuter has few peers. Just add
a front fairing to keep the toes warm and a Novosport tailbox...
