American Bicycle Group became the parent firm for several well-known brands, most notably Litespeed, but also Quintana Roo and Merlin. Some cross-branding of products occurred, and the TiPhoon is one such example. The TiPhoon is simply a Litespeed Blade with different decals.
The Litespeed Blade (read, Quintana Roo TiPhoon) is Litespeed’s high end titanium time-trial frame, featuring aerodynamic tube shapes and extensive use of 6/4 titanium. The images below show the frame design from 2003.
