Yeah, since basket pics are now in the chat, below is a pic of my commute/tour bike with a 139 basket plus Swift Motherloaf bag on the front.
The 139 basket is massive, but I had to get it because a 137 basket and bag are too small for my laptop to fit without being angled and taking up a lot of bag room.
If Wald made a 138 basket, that would be perfect.
Anyways, its just a cheap wire basket that is ziptied to the platform of a JANDD Extreme Front Rack.
I looked for about a year and a half at various racks- porteur, demi-porteur, pizza, etc to put on the front because I wanted to lighten the overall carrying system. A pizza/porteur rack bag from ILE or OuterShell would have been used since they direct mount to the racks. Ultimately though, the bag I got was new and half off, and I already had the front rack so I just sucked it up and bought the basket. Admittedly, it is really versatile to have.
