It takes a special someone to get excited about a new fork for gravel adventures, and yet, here we both are!
All new here at Sour is what we’ve been calling the Business Fork. Seeing as we already have the Party fork, it seemed fitting that we added a Business fork because, at the end of the day, it’s all about balance.

The Ying to the Purple Haze’s Yang
A fully featured fork for all the fun. We built the Business fork to have all the features, routing, and mounts, without feeling bloated or looking too busy… I mean, it has to look a little busy, it is the business fork after all!
It was important to add all the safety margins we could while putting all sorts of holes in this fork, we’ve seen how you ride your gravel bikes! In fact, getting the holy grail EFBE Tri-Test certification was number one on the list of goals with this fork. And wouldn’t you know it, we go it. Not only did we receive EFBE certification, we were apparently the first fork of this kind to pass the Tri-Test and we couldn’t be prouder!
160mm Flat Mount Brakes
The front brake is flat mount, direct mount 160mm. If that didn’t make any sense, no worries, allow me to explain. With our fork, you can install a flat-mount caliper without an adapter. That adapter that generally comes pre-installed with your new brakes? Take it off, give it to a friend, you won’t be needing it on our Business fork. For those of you thinking it, no, it won’t fit 180mm.
Fenders? Dynamo? Rack? Yes.
Living in kind-of Northern Europe, it gets dark pretty early in the winter. We love dynamo hubs for this reason, so having clean and trustworthy dynamo cable routing was also paramount. We went the standard cable through the fork leg route for cabling, but we got creative at the fork crown. By moving the holes around and adding a 3D printed guide up there, we keep your front light cable tidy and safe as well as your rear light cable, should you choose to be so safe!
The last design note before the specifications below is the weight capacity. By clearing the EFBE test, we can say that mounting a rack is no problem! As long as you keep the total load under 15kg, you’re good to go. Same goes for cargo cages, keep it under 7.5kg per fork leg and you’re scot-free!
For racks, you are required to use the lower eyelet. This eyelet uses both fork leg walls and is super strong.
