T1 expanded its line when Spanish BMX rider Ruben Alcantara joined the team. In 2004 T1 produced a new frame for Alcantara, lighter than the Barcode and with a different shape and a press-fit bottom-bracket. For 2005 T1 introduced a new double-diamond frame for Garrett Byrnes and incorporated an integrated headset for all their frames. In 2007 it made the 5-a-day, a lightweight street frame used by Danny Hickerson and Joel Moody. T1 also made a refined Garrett Byrnes frame in 2007, the S.F.A.
