I had the same problem with an Octane One hub with a 9t driver. I don't know what the front chainring is on the Evil Faction, but trails company Inspired makes a 22T chainring that makes the ratio a little easier on the knees. Ultimately, I ended up building a new rear wheel with a Hope Pro4 DH/trials hub. Not the cheapest, but at least I can work with different gear ratios now for the track.
