Twenty Nine Inches has obtained an Origin 8 Black Ops 29″er carbon fork for testing. The fork was especially chosen for the “An Experiment In Front End Geometry” series that is still in progress. This Black Ops fork is also in one of the optional colorways for this fork, that being a white painted crown and drop outs. The other option has black crown and dropouts. Not only that, but you can choose your axle to crown length, as well. More on that in a bit.

As you can see from the photo above, this fork is compatible with cantilever brakes. The interesting thing about that is, the cantilever bosses can be removed for a cleaner look when running disc brakes on the international standard tabs on the left drop out. The bosses for the cantilevers are hinged and use two 3mm bolts to secure the “clam shell” boss onto the fork leg. The bosses clam shell is lined with rubber to keep them from rotating on the carbon legs. Interestingly, one can position the bosses anywhere up and down the length of the fork, leaving one to believe that you could use the fork for 26 inch, 650B, or 29 inch wheels with rim brakes.

Origin 8 offers this fork in two axle to crown lengths, as mentioned. The longer of the two is listed as being 465mm and the shorter version, which we opted for, is listed at 420mm. However; when we measured the fork for ourselves, we found it to be 430mm axle to crown. Also notable is that while the weight of the fork is listed at 770 grams with an uncut steer tube, we found that ours weighed in at 950 grams with the brake bosses installed. Once the bosses were removed, we weighed it again with a result of 860 grams. Still a pretty light fork, but a bit disappointing when you consider this fork has 35mm less material in each leg than a similar fork we tested that weighed 950 grams with a star nut installed.

The Black Ops fork has a listed 43mm offset, so we felt it would be the perfect foil to the Blackbuck fork with its 51mm offset and 440mm axle to crown height that we have tested already. Actually, we were quite pleased to find that the Black Ops measured out with a 430mm axle to crown, which will make the comparison, (and set up!) that much easier.

The look of the Black Ops fork is quite nice. If white works with your current bikes graphics, you will like the pearly white paint on the drop outs and crown. The carbon is finished out in a “3K weave” and has a flat clear coat over it for that “graphite gray” look. The fork instaled with no drama, and we will be testing it out on a trail very soon.
