Hubs Tested, Fatback approved! Part 1

Here at Fatback, we strive to be the best we can be. Since 2007, we’ve burned the midnight oil working on solutions to the problems faced when riding in cold, and severe cold conditions. One of these issues is rolling resistance of our fat bike hubs. From the beginning, we have worked with our manufacturers to reduce friction. After more than a decade of tweaking and perfecting our hubs that we use on our carbon fat bike wheels, we finally decided it would be a great idea to put the hubs to true scientific test. The University of Alaska Engineering Department developed a setup using a constant speed lathe that could operate at a constant load at any given temperature and a load cell was used to measure drag (one of these was broken by a poor performing hub). This setup was used to test the rolling resistance of many competitors and aftermarket hubs and of course ours, in extreme cold temperatures. The test was to be performed at room temperature, 15F, and -20F. At a fixed RPM, they would test both rolling resistance, and coasting resistance, which would measure the drag of the free hub body.

Hubs tested:

We tested our older production imported hub, as well as the newer version, the Fatback AK Edition-SL, along with the hubs Hadley makes under our brand name, which have been the gold standard of quality and performance for over a decade now, and some competitors.

Check out the results at 15°:

After the first round of testing at 15° we were a little surprised that our Alaska Edition hubs performed almost as well as the Hadley made hubs. We knew we had made some great improvement, but didn’t think we would be that close.

The University is a little backed up at the moment, so the -20° test results won’t be available for a couple weeks. Stay tuned!
