We have good taste, what can i say ?
The Roubaix has a timbuk2 which i recommend. The bag on the cross check is peformance brand TransIt that i wouldn't recommend if it were free. It is ugly, bulky and so poorly designed that it had to be mounted Upside down in order to prevent it from sagging and swinging all over the place. the only thing i like about the transit is that it has a spot to clip on a blinky where my Timbuk2 does not.
Rei has the timbuk2 bag for $20 on main site and $10 on outlet. its not the greatest but i like it and its cheap.
