Level 4 This Level provides a frame that is 100% competition oriented. If going fast is the priority, this is the level you want. We use 6al-4v titanium alloy in the main triangle. This material provides the best combination of stiffness, lightweight, and durability in the cycling world, period. (If carbon fiber was actually better we'd use it, but that's another story). We multi-shape the tubeset to very specifically "dial-in" the performance expectation of the frame. Our House Blend (4) versions use a "compact" set-up that is best suited for competitions like stage racing over varying terrain. Should you have a unique fit need or want a frame built for a specific racing style (such as criterium or time-trial) you will want to choose a Fully Customized design. Base price includes finish options of either a natural brushed titanium or 1-color full paint. Customized paint and graphics options are available for both Houseblend and Fully Customized frame designs.
