What’s the difference? I mean, what is one more designed/suitable for then the other?

The numbers suggest the boot zipper is more touring/bike packing focused, the big dog more winch and plummet.

For instance Ha 65 on the big dog 70 on the boot zipper

Bootzipper is rigid only. Big dog a slack hardtail. Different beasts.

Bootzipper is designed around only using a very short, rigid fork but still keeping a slack head angle to allow it to cope descending. Old skool xc, gravel rides, travel that includes bumpy bits up to and including as lumpy as you can cope with on a solid fork and chunky tyres.
Bid Dog is a short travel, long framed hooligan hardtail. Yes, very different.

Though to confuse everyone even more, we’ve just released a Rigid option on the Big Dog.

Rigid would be my choice.

Where can this option be found? Cant see them on the site.

Aah, would this be the Selcof Carbon 27.5+/29er Fork FOSEC27?

Are these available to stick in the basket along with a frame?
