Since Black Sheep’s bikes are pretty much all one-off custom creations to suit the customers’ needs, they often defy categorization. Or, at least, span too many to be easily defined.
One of the latest is their Adventure Fat Bike, which has a new rear end that, as they put it, has 25mm of “catastrophic” travel in case the tire bottoms out. So, yes, if that balloon on the back hits something so hard that you’re landing on rim, there’s a bit of give in the frame to help prevent damage.
Take a look at the rest of the bike, a matching “catastrophe” fork and some of the best head badges ever…
The bent stays and forward mounting position allow a little flex. Not suspension so much as insurance.
They make some pretty swell titanium handlebars, too. On the right is their standard truss fork, which have fore/aft flex to simply mute vibrations.
But on this fat bike, they build something new…
This Blade Runner / Deathsplosion fork got its working name because it’s so new they’re discouraging anyone to actually buy it yet (it needs more testing). It maxes out at 40mm of travel that’s really designed to just soak up the big hits that would otherwise destroy a tire. It’s built to have very stiff travel, not really be a suspension fork.
The bolt at the top of the seatstay yoke separates the rear end (along with the sliding chainstay design they use on a lot of their bikes) so you can more easily pack it for travel.
