I asked BF how about adding the head tube boss so I can Xfer my Brompton bags.
they declined . as a result, I'm still not on the BF bandwagon.
the head tube mounted clip with my usually stuffed Brompton Touring bag,
actually adds stability to the handling of my Brompton
and there is no deterioration of the quickness of the steering response ,
as it inevitably is when you add mass to the fork.
O bag is one of their Downtown Bags, + 2 accessory pockets,

and I suppose Integrating the QR clip,
rather than making the bag slide over the standard Brompton Bag frame.
Carradice cotton canvas bags use the Brompton Bag Frame + Carradry is their waterproof offering.
costs 2X as much , about $300. as the downtown bag,
and has no more volume
than 1 front roller pannier, as i read the Specs.
