Sour Bicycles Business Carbon Fork - Tapered | Flat Mount | 12x100mm
The Ying to the Purple Haze’s Yang This fork is the business! Made for the Sour Purple Haze, it’s ready for long adventures, short adventures, adventures to the local café, as well as adventurous long walks on the beach at sunset with your favorite person… …as long as it’s adventurous! Sour made the Sour Business Fork specifically for their Purple Haze Gravel frame, but this fork will fit any bike that shares a similar axle-to-crown length as the Purple Haze. With it’s cargo cage mounts, internal dynamo routing, rear light routing, front rack mount… Okay, there are just too many features to note here. Oh! And it is the the first fork of this kind that has passed the EFBE Tri-Test. Humble brag. The front brake is Flat Mount, direct mount 160mm. If that didn’t make any sense, no worries, allow Sour to explain. With their 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 the Sour Business fork. For those of you thinking it, no, it won’t fit 180mm. Living in kind-of Northern Europe, it gets dark pretty early in the winter. Sour love dynamo hubs for this reason, so having clean and trustworthy dynamo cable routing was also paramount. Sour went the standard cable through the fork leg route for cabling, but they got creative at the fork crown. By moving the holes around and adding a 3D printed guide up there, it 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, 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.
