Tandems at NAHBS, including new Ritchey Beakaway tandem
Photos are starting to appear from the 2012 North American Handmade Bicycle Show. Almost all the bikes on display are fascinating to look at, with interesting custom details and impressive workmanship - far more interesting than all of the stock builds at Eurobike and Interbike IMO.
For tandem enthusiasts, probably the most interesting thing is that Ritchey are going to start producing a tandem version of their Breakaway frame. They have been making multiple versions of single-bikes (mountain, road, and cross) for several years using a system that allows the frame to split into two that is far lighter and more sleek than S&S couplers, see their website here (although that suggests that they are now only offering the cyclocross version). At NAHBS, they were showing a tandem that uses a similar system, as shown here on the massive Bikeradar gallery of NAHBS photos (plus the two subsequent photos show it in more detail).
Paketa were also showing off a couple of tandems, see the photos starting here. These include a race model equipped with a Gates timing belt and Ultegra Di2 transmission that weighs about 10.5 kg, plus a time trial tandem with rare Sweet Wings tandem cranks.
