The Roark Solution - Mach 2
Aero down tube and seat tube with rear wheel cutout

Wow… It is by far the stealthiest looking titanium frame on the planet!!! The Roark Mach 2 frame uses the same aero down tube as showcased on the Roark Mach 1. The next pièce de résistance is the aero seat tube. We have a rear wheel cutout that has been referred to as “a fabricated piece of art”. Instead of welding a flat plate on the back of the seat tube, we have utilized a slice of tubing which provides a concave shape for the wheel to tuck into. This design allows the seat tube to closely shroud the tire, creating a maximum aero advantage without the need for troublesome horizontal dropouts.

The next item that will catch your eye is the seat tube clamp. We are often asked “how did you do that?” The answer – we use a billet seat tube cap. The seat tube is comprised of two pieces – a billet cap that is pressed and welded into the seat tube. This cap starts out as a 2-1/2” diameter chunk of billet titanium that is machined into shape on our CNC milling equipment. During this process not only do we shape it to match the seat tube profile, we also machine the seat post clamp into the billet.

Since Roark’s are 100% custom, this means that anyone can have an aero frame and be comfortable. Most aero bike offerings consist of a ‘slammed’ triathlon geometry that won’t be comfortable to most riders. We design and build bikes for anyone - young, old, small, large, triathletes, roadies, and male/female. With a Roark, now everyone can benefit from an aero frame.
