Designed and built in January 2024 for the Philly Bike Expo, this frame was used to test several design ideas, fabrication, and finishing processes. The frame’s main tubes are filament-wound using 3D printed mandrels and molds, and are joined using a combination of pre-cast junctions and tube-to-tube construction. All tubes are tapered and/or shaped. The elliptical top tube tapers to a height of 15mm and transitions to seatstays molded to complement the contour of the iconic eeBrake. Other details include a molded chainstay yoke, tapered IS41/47 head tube, integrated seatpost, custom seat mast, and handmade carbon saddle. Finished in gloss clear with a gradient panel on the downtube, the carbon layup is visible throughout. The frame is designed to be stiff, light and responsive.

Build highlights include: Appleman 2XR cranks with a prototype Appleman 1x chainring, Cane Creek eeBrakes, and a pair of gloss Princeton CarbonWorks Alta3532 wheels.
