Surly Troll 26" 11/8 Nonsuspension Threadless Fork, Black

The Troll fork is just like the one that comes with the Troll frame. Three-pack cage mounts, fender eyelets and unlike other forks, it’s designed to accept a front rack while using a disc brake, via through-blade threaded mounts in two places on each fork blade.
