Fat bikes and gravel grinders may be the hot new categories at this year's North American Handmade Bicycle Show, but in terms of numbers, the show floor is still dominated by traditional road bikes. Check out the first round of some of the ones that caught our eye in the image gallery at right, plus details on a few select models below.
Alchemy put its Helios model on a major diet to create the Helios SL. While it uses the same mold as the standard model, changes to the underlying materials and lay-up have brought the claimed weight down to just over 700g for a 54cm frame – a decrease of more than 25 percent from the original Helios.
Even more exciting, though, is the all-new Aiolos titanium road frame, which was designed for Alchemy by Ben Serotta. Alchemy builds the Aiolos with an oversized main frame for a responsive feel and tapered stays for a comfortable ride. Other features include a 44mm-diameter head tube, a PF86 or PF30 bottom bracket shell, custom titanium dropouts.

Calfee's latest Manta Pro carbon road frame is easily the company's highest-performance model – and perhaps its most radical. While the main tubes' huge cross-sections and ovalized shapes scream stiffness, they're coupled with a suspended rear end that provides comfort and traction.
Calfee's manta pro uses enormous tube profiles for what we would expect to be an unyielding stiff chassis - except that it cleverly integrates a rear suspension design to take the edge off of the road: - James Huang/Future Publishing
The system is similar to Moots' long-running YBB system with a small spring tucked inside a telescoping, tubular seatstay wishbone assembly. Down below, titanium struts are used beneath the chainstays to provide additional strength. Calfee offers five different spring rates to adjust for rider weight and ride preference, and the company can also build the Manta Pro with a fully rigid rear end for those that want a more traditional feel.

Rim brake and disc brake configurations are available, too, along with thru-axle dropouts and optional braze-ons for racks and fenders.
Craig Calfee also displayed his custom chops with a wild modular carbon fiber road tandem. A clever arrangement of bolt-on stays and S&S couplers allow the bike to quickly and easily convert to a single as needed. As for the price… don't ask.

Remember Delta 7's wild IsoTruss carbon fiber 'tubes'? The technology is back, only now the patents have been purchased by Utah-based Razik Bicycles. Razik says it has refined and greatly improved Delta 7's original concept to produce a new road frame called the Vortex that's far more reliable than before – not to mention much better looking with far better cable routing and finish work. Rear ends are molded in-house, too.

Ritchey unveiled at this year's NAHBS a new carbon fiber version of its popular Break-Away travel road bike. The new carbon chassis is, as expected, lighter and stiffer than the current titanium and steel versions. However, Ritchey has also opted for slightly smaller-diameter tubing and thicker tube walls so that the bike can still be easily packed – and survive the journey.
Ritchey will soon make available a new carbon fiber break-away travel bike frame. retail price will be us$3,199 for the frameset when it goes on sale in august: - James Huang/Future Publishing
