A few things: (1) I didn't realize Super Record 11 front shifter ran with a triple crankset.
It doesn't, officially. In fact, I had been planning to switch the SR11 with the Record 10 from my BMC. However, to the surprise of both Madcow and myself, the 11 cassette fits on the DT 240S, and the RD shifts just fine. Not so, however, for the FD, which is a 2006 pre-Quick Shift Record, which doesn't like the QS shifter. I'll have to figure out what to do with that, the default being to use 2009 Campy Comp Triple FD, which is a shame as it is hardly even Centaur level.
(2) The frame seems a bit heavy for a Dragonfly. The Ruegamer is listed 2.0 to 2.5 kg.Ruegamer is down
, so isn't an option right now.
But Calfee says
"with a fame weight of less than 6 pounds, the Dragonfly Tandem weighs in as the world's lightest tandem!" (6 lbm = 2721 g).
The Ruegamer Uberlights were light but we don't know at what stiffness penalty. The more apt comparison is the standard Ruegamers. Probably the ultimate (as in the last
) Ruegamer Tandem was Whereswaldo's standard received in April. It weighed 2.68 kg (5.91 lbs)
Making this tandem light would be a lot easier with a 5.91 lb frame. It would project to 21.67 lbs. Edge 45 2.0 tubulars would save 290 grams, and get it down to 21 lbs even. Now, if this were a djconnel sized frame, it would be bordering on sub 20 lbs. But alas, Reugamer is no more, and Calfee has a carbon tandem monopoly. Would Parlee be interested in making a carbon tandem? Nope, I already talked to them. Too expensive to make the molds they say.
The Calfee web page may wax a bit optimistic about their weights. The Dragonfly's weight came in roughly what Calfee had predicted to me prior to its being built. Calfee weighed the frame nude at 2930 gm (6.45 lbs). It was painted, and shipped to Fairwheel, where it weighed 3210 (7.08 lbs), gaining 280 grams. That seems like a lot for the clearcoat, maybe Fairwheel included the 116 gram eccentric in the frame, that'd be nice.
: I'm not able to view the photos anymore. I need my bike porn fix
. I believe the problem is flickr uses temporary URLs.... imageshack.us is better. For flickr, link to the HTML page associated with the image.
Geez, I've had problems with these images. Thanks for the Imageshack tip, it seems to work fine and will now be my default.
