To tighten the chain, you rotate the hub around the axle and the dropout; because the axle is in an eccentric, this makes the frame rise or drop on the axle. While holding the wheel in place (and thus, keeping the chain taut) you tighten the allen nuts.
IME (I used the ENO on 2 frames) 2 teeth difference is the max that the ENO can handle; and depending on the chain and the ring and the cog, sometimes it can't even accommodate 2 teeth. It couldn't for the early '90s Diamond Back mtb frame I used it with Overall, for things you can count on, I would count on the ENO to take up slack for a single cog; but I would not count on it being able to accommodate a second cog , at least one that is 2 teeth larger or smaller than the first. Also, moving the wheel/rim may put the rim out of place for rear brake pads; I fixed this by removing the rear brake (I used fixed cogs). Also, moving the wheel means to move it up or down relative to the ground; this may mean, depending on clearances, that your tire rubs against the fender or even the seatstay bridge. When I installed fenders on the 1995 Riv Road custom, I had to be careful to rotate the wheel downward, against gravity, instead of letting it naturally rotate upward as the weight of the frame/bike would cause it to do. If it rotated upward, it would rub against the fender.2 co You may be able to get away with a 2 ring/ 2 cog arrangement, if the respective combinations add up to the same teeth. But note that tightening the chain with an ENO is slightly more complex an operation than when tightening it by means of an axle sliding on a long dropout. With 85 lb, I daresay it might be cumbersome. Personally, while I think that the ENO is a wonderful devise, I would hesitate to recommend it for anything more complex than taking up slack for a single cog and ring.
