INTERBIKE 2009 – Litespeed has long since been known for their use of titanium frames. The possibilities of carbon however, are undeniable. It has taken Litespeed two years to perfect their re-entry into the carbon market. The Archon C-Series, new for 2010, features three bikes: the CÃ‚Â¹, CÃ‚Â² and CÃ‚Â³.While not designed as Aero or TT bikes, they incorporate several aerodynamic ideas. Some of which were carried over from the Quintana Roo CD 0.1 design, another product from the American Bicycle Group.
The CÃ‚Â¹, only available as aÃ‚Â frameset, is their flagship carbon frame and uses unidirectional carbon, nanotube construction and internally run cables. Built as seen above, with Dura Ace shifters, derailleurs, and brakes/ Zipp SL 145 stem, SLC 2 bar, VumaQuad cranks, and 808 wheelsets/ Ã‚Â and ProLogo C.One Nack saddle: the CÃ‚Â¹ weighed in at 14 lbs 13 oz. Frameset MSRP: $3,000.

Above is the tapered steerer fork that tapers from 1.125″ to 1.5″. Although the carbon layups differ, the frame geometry are from the CÃ‚Â¹ to the CÃ‚Â³ are identical.Ã‚Â Litespeed’s engineers have varied the tubing proportions, cross sections, carbon lay-up and profiles to ensure the optimized ride quality and performance throughout the full range of sizes.

The “AeroLogic” incorporated into the C-Series includes a integrated seat mast, interrupted seat tube and aero shrouded water bottle mount.
Here’s a better angle on the aero shroud water bottle mount. The bowed fork design was borrowed from theÃ‚Â Quintana Roo CD 0.1. The idea is to get the fork and rear triangle out and away from the wheel sets in order to maximize their aerodynamic efficiency.
Like the fork, the rear triangle is bowed out to not interfere with the areo benefits of various wheel designs. Also, theÃ‚Â asymmetricalÃ‚Â morphed seat stays were designed to increase aero performance, stiffness and ride comfort.
The C-Series uses a BB30 bottom bracket. Internally run cables are only available on the CÃ‚Â¹ frameset.
CÃ‚Â² and CÃ‚Â³ are both sold as complete bikes. The CÃ‚Â² has silver and red paint on top of black carbon.
