    Tandems at NAHBS 2011

    The North American Handbuilt Bike Show opened today in Austin, Texas.



    NAHBS is the cycling industry's premier showcase for tandems. Tandems are oddities at Interbike, but at NAHBS are front and center. Last year tandems won three of the 16 awards.

    Photographs are trickling in at sites such as Flickr, Picassa, Twitter, etc., as well as the NAHBS site. I've collected many of these at Flickr Gallery here, where they can be enlarged.

    If anybody has any NAHBS tandem photographs, please post or link them here!

    Calfee Tetra. Note the Di2 (which is one reason it is a double). Where's the Di2 battery? Calfee has devised a Di2 battery mount hidden in the seatpost. Note that the disc rotor appears to exceed 203 mm.

    Nice collection....

    I'll most likely feature it in one of this week's blog entries with due credit where it's deserved.

    There is a photo in your collection from the Bilenky display that's very applicable to tandems -- the Phil Wood Rohloff hubs shells -- that was not shown on a tandem. Instead, it was on Bilenky's single show bike: http://farm6.static.flickr.com/5297/...6abba62e_o.jpg. More on the Phil Rohloff shell here.

    An AMAZING bike that seems to have all kinds of very cool retro parts, polished Phil components and hundreds of hours of paint work.

    Kent Eriksen won Best Tandem, for the Eriksen Ti Tandem.

    Quote Originally Posted by NAHBS

    Eriksen’s Ti Tandem is a fully customized 29er race machine with immaculate welds and a sturdy build.

    It sports a massive 2” downtube and boomtube, a size rarely used in other bikes.

    According to Eriksen, their size and form help minimize the flex symptomatic of some tandems. Their form also allows for perfect joints with other tubes.

    Flex is further mitigated by the rear cross tubing design, which also affords greater clearance for the generally smaller rear rider (in this case, Kent Eriksen’s wife Katie).

    Other highlights include a 2” head-tube which tapers to an adapter-aided 11/4”, again to maximize stiffness, a maverick DUC 32 DH double-crown DH fork with a 20 mm thru axel to provide front suspension, and a weight-saving integrated stem and seatpost for the rear cockpit, which was designed in-house.

    One-inch chainstays are meticulously formed to accommodate proven breezer dropouts, a huge disc rotor, and ample chainring clearance.

    Through intimate knowledge of his chosen material, Eriksen has managed to build a sub-35 lb race tandem 29er, designed with great attention to detail from head-tube to rear dropouts.

    Well deserved!!!

    I talked to Katie and Kent about both a 700c as well as a 29er tandem over the past two years, but at the end of the day our pockets just weren't deep enough for either bike. But, for those who have the resources and are looking for the ultimate road or off-road tandem, a Kent Eriksen should definitely be on the short list.

    I'll have my photos up in the next day or two. I took about 380 photos and I'm sure my wife got that many.

    I'll separate the tandems so that they are easy to find. Ironically, I only took two of mine at the show...

    45 in total. Some are trash, some are in need of editing and some are good as is. 45 in total, all are uploading now.

    Ironically, until looking over these photos I didn't realize our timing belt was out of sync a bit..

    You really liked that Bilenky, didn't you, Brad? :-)

    A drool-worthy photostream if I ever saw one.

    That was my wife's favorite. Though, 3 days at the show, we grabbed all the tandems several times. Multiple settings on most setups. Tandems usually don't get enough coverage. I wanted to make sure we had some decent stuff. My favorite was the Ti-cycles; though hardly as interesting as the Bilenky.

    It was quite frustrating to get the bikes. I think next time I'll come up with a press-pass.

    I will be there. I want to get a press pass as well, pretend to be a reporter, and file reports. The BF tandem contingent will definitely have to get together.

    The Paketa people pledge they will exhibit their bikes next year.

    Santana tandems are handbuilt in the US, and Santana too should be at NAHBS. Maybe Santana will be a trendsetter, and in the future we'll see edgy NAHBS bikes with 160 OLD and WinZip 10" discs.

Every Santana is the culmination of expert design, engineering, welding, painting and assembly.

    Nice to see some tandem coverage at CyclingNews

    Quote Originally Posted by Cycling News

Calfee built the frame with Shimano's Dura-Ace Di2 electronic drivetrain and modified it with his own extra-long wiring harness, quick-connect plugs, and an internal battery setup of his own design housed inside a seatpost. The rear derailleur has also been modified with a longer pulley cage to increase the gear capacity.

    Other high-end parts include Lightning two-piece carbon cranks (the design on which Specialized bases its own FACT cranks), a Gates Carbon Drive timing belt, Zipp carbon-aluminum clinchers, and a Enve Composites cockpit components. Claimed weight for the entire build as pictured is just 12.7kg (28lb).



    Calfee's Tetra tandem is not only impressively light but also relatively easy to travel with thanks to S&S couplers and a disconnectable Shimano Dura-Ace Di2 wiring harness.



    Lightning carbon fiber cranks fill out the shells on the Calfee tandem.

    I certainly do like the weight weenie theme, Enve fork and components, eebrake caliper, deep carbon rims, Profile Design Cobra stoker bar, and Lightning cranks.

    I love the folding Bilenky with the Brooks saddles and the "flask" in lieu of a water bottle!

    Bikerumor has a write-up on Cyfac at NAHBS, and Brad's tandem leads the story!

    I must say, the most irritating thing about having a Gates drive is that all any non-tandem person will notice about your tandem. Brad's tandem has all sorts of interesting features, but Bikerumor can't get past the Gates drive, as if this was something new. Co-Motion had a Gates drive tandem at Interbike in 2008. But Bikesrumor is is just gaga over a belt drive on a tandem!

    NAHBS for the third year was Cyfac, a relatively little known French bicycle maker, but one with an illustrious history.

    Standing for Cycles Fabrications Artisanales des Cadres (Artisan-made Bicycle Frames), the company, which is based in the Loire valley, south of Paris, has been around since 1982, and does all its design, production and finishing under one roof. Originally, it made high-end custom frames, handmade to individual professional’s measurements and badged up by other bicycle brands to be ridden by the pro peloton. At the high point, about a third of the division one riders were on Cyfacs – although you wouldn’t have known it, since they were painted in the colours of MBK, Peugeot and others...

    Also on the stand was a stunning carbon tandem, made for a husband-and-wife team, with a custom supporting tube configuration (from the front seatpost back), that suits both the riders’ aesthetic desires and the company’s desire to keep the bike as stiff and responsive as possible.

    An interesting feature was a belt drive on between pilot and stoker (which Bilenky had also done, on a steel tandem on display at his stand). Cyfac plans to experiment with a fully belt-drive tandem, using a Rohloff hub – if the customers want, that is…

    Cyfac tandem getting a nice pic at CyclingNews.


    Not surprisingly, Cyfac's full-carbon road tandem was remarkably light, especially with this high-zoot build kit.

    This almost makes me want to go ride it. Two more weeks and this silly marathon thing will be behind me... Then back to cycling.
