View Full Version : ENO Adjusting

Hey folks - Just wanted to get an idea -- from any ENO hub w/disc riders out there, I have two questions:
(1.) how do you adjust tension in your chain? I haven't found a smooth way to get the tension right. I either rotate it too far or not enough, and it seems like i have a ton of difficulty getting hte wheel to seat properly when I try to adjust. It seems like I would need an extra set of hands to make it work.
(2.)I recently had to replace one of the mounting bolts on my rear disc caliper and I don't know if it shifted the position or what might have happened, but since then I cannot seem to get the tension right without getting a constant rub on the rotor. I checked the rotor and I don't see any bend in it, so I have to believe it's somethign int he way it's mounted or set-up. Anyone else ever have this issue pop up?
Thanks for any help you can give me!

I don't know how much help this will be, but...
I've got the ENO disc on my Gunnar, set up with a mullet (rim brakes in the rear, disc front). With my rim brakes, I couldn't rotate the hub up and back like they say to in the directions because it put the wheel too far back for the rim brakes to make contact with the rim. I have to rotate mine forward, and yes, I often feel like I need about three more arms/hands. Since I don't have a disc rotor on the hub, I use an open-ended wrench on the 'center' part of the hub to rotate it and tighten the chain, then tighten one of the axle bolts. It stays put so I can then tighten the other side. Supposedly though, if you have the disc adapter the wheel should rotate up and back when the bike is on the ground, naturally tightening your chain. I would think you could adjust how much the wheel tightens/pulls the chain by how much you weight the bike down. That's what I did before I realized my brakes were bogus with that setup.
On the second part, it sounds like your axle might not be seated correctly in both sides of the dropouts.

I was looking at it again last night, and I think you're right on on the second part. It doesn't help that I have a little kink in the rotor itself (it's been that way for a long time, but whatever happened with the axle seems to have exasperated the problem. Might have to get a new rotor no matter what I do.)
I would actually prefer to turn it into a "mullet" (that's just an awesome term, by the way), but I can't do it: my bike is an '06 OCLV and it only has disc mounts. It's a shame, because it sounds like your method of adjusting would just work better. As it is, if I tighten one side, because of the way the disc has to sit, I have to have the whole fit dialed already because I can't budge the other side (so I might as well have tightened both at the same time.)
Thanks for the ideas, though. Oh well -- I still think I'm better off than my buddy, though -- he has an older 9.9 that he converted to SS but uses a Singulator. That thing has caused him no end of trouble.

is it safe to assume that you are using the eccentric eno with the eccentric adaptor for your caliper?
i didnt see any mention of you rotating the caliper after rotating the hub...thats all.
i will also assume that you are running vertical drops (such the need for the rotation) in that case i dont understand how you could be having trouble seating the wheel properly. can you explain this further?
when i tension an eccentric hub i completely ignore the brakes, deal with one issue at a time. backwards/forwards, up/down, its a matter of personal pref and perhaps other factors with your set up. my personal choice is to let gravity do the work. i leave the bike on the floor, loosen the bolts and let it go from there. tension tends to happen ok, if it needs help i hold one of the axle ends in place while i snug up one of the bolts.
with tension achieved i then concern myself with rotating the caliper...
and finally then i deal with the side to side and pad adjustments. changing pads, rotors and yes even bolts all seem to have minute impacts on the setup. i adjust the caliper regularly. if disc brakes worked prior to going eccentric on the hub they should work after...if the rub continues you may have rotated the disc into contact with the upper inside of the caliper body...i've done that...

I put the chain on and drop the hub in the dropouts. From there, I put my hand between the seat tube and the tire and just push backwards a bit while I tighten the hub down. Tightening down the drive side first seems to make things go better.
(2.)I recently had to replace one of the mounting bolts on my rear disc caliper and I don't know if it shifted the position or what might have happened, but since then I cannot seem to get the tension right without getting a constant rub on the rotor.

I had a problem with this when I was using a longer chain length. The disc mounting bolts would just rub the lower end of the eccentric mount for the disc caliper. Very annoying. The dremel tool fixed it.
What I'd like to know is how do you get this hub to stay put. I can start out with perfect tension but after a two hour ride the hub has rotated forwards slightly making the chain quite loose. I'm strong enough to easily break my tools and I'm afraid that I'm going to strip out the mounting bolts if I go any tighter. Thoughts?
