    Is anyone happy with their Bio-centric ebb?

    I have seen plenty of negative stuff; but negative is always easy to find.
    I am thinking of getting a One Nine. I already have an Air Nine and a RIP so I am quite happy with Niner bikes. I also have a XXIX and love singlespeeding. So I'm only asking for feedback on the ebb

    Thanks
    Richard

    Have been riding a One 9 for 2 months now, logged over 400 miles on it. Not one time has it slipped or creaked. So far it has been my favorite SS set up.

    I have been using the Niner EBB for 2 years now, first on a SIR9 and now on a One9 and although it is not a perfect system, what is? On my SIR the EBB was flawless, on the One9 I had to mess with it a bit to get it right but it was really not a big deal. I am sure there is a small number of people who have legitimate issues but for the most part, the people who are posting here on MTBR about problems they can't resolve are probably the same people who bring their bike in to the shop to get a flat repaired. In the unlikely event you have issues, if you have any mechanical inclination at all, you will be fine. You hit the nail on the head, it is easy to find people bashing it but the majority of users are happy and too busy enjoying their bike to post up on the internet.

    Another happy owner.

    It does have to be set up properly but once that is done it works fine. Had a few initial problems adjusting it with an external BB but once I realized it was NDS bearing pre-load causing binding the EBB itself has been fine.

    I am not dissatisfied. It's finicky, that's true. Every few months mine will start to creak so I remove, clean, reinstall according to instructions and I am good to go. I use one million foot pounds of torque and that pretty much solves any problems. Except stretching out the M8 bolt. But bolts are cheap.

    MIne continues to creak and I've tried all the fixes. I'm thinking of lubing the BB shell, in the hopes that that will quiet it. Drives me crazy, but live my SIR9.

    I had some creaking a couple times. I loosened the EBB, drizzled some dry lube into the gap, and tightened it back up. No more creaking.

    Maybe I am a lucky one. My SIR9 does not creak at all from day 1. Earlier this year I bought the frame on eBay (as used), and BikeBling assembled it. I don't think they did anything. Neither did I.

    I'll have to give that a try. I'm going to attack it this week, this is prime riding time here in the NE.

    My SIR was a big hassle till I figured out the right combination of voodoo to get it working right. I bought a One9 a few weeks ago, prepped and wrapped the EBB like I did with the SIR and it's been rock solid. Not sure I'm crazy about the Biocentric but I love both frames enough that I'd buy another one again in a heartbeat.

    Did you wrap it with teflon tape? My sir 9 is two years old. The creaking drove me nuts, so i went with the carver. It worked for a while and then the creak came back. I wrapped my old 1fg with teflon and it worked great, but i was told not to with the niner ebb. I have tried every method under the moon and its still creaking....to the point i wanna huck the thing off a cliff if im riding without the ipod. I'm gonna order the new EBB and give it a shot, since my riding buddy put one on and cured his problem.

    I love the ride, but the noise is unbearable.

    The Niner installation pdf tells you to wrap Teflon tape around the shell.

    Yup. With my two frames teflon tape has been the only way to keep things from slipping or creaking. After cleaning and scuffing the EBB I do two wraps of tape. On my SIR it's a tight fit so I do my best to push it straight in. It helps to mark on the frame where the EBB needs to be positioned so you're not doing a ton of adjusting afterward and possibly messing up the tape. I torque to 18 ft/lbs or so. Occasionally I'll get a bit of creaking but it's not loud and never lasts long, and zero slipping.

    Because of the tight fit it's a real pain to adjust without loosening the cranks so I don't change gears on the SIR.

    First couple rides after building up the SIR were nice and quiet. Then came the first ride w/ mud/sand/rain (mountainbike conditions) and the creaking has begun. There have been no issues with slipping but the creaking is there even after througoughly cleaning disassembling and reassembling per factory recommendations.

    I'm at 1 year with mine, and I'd say 6-8 adjustments due to cog changes or tension adjustments soon after those cog changes. I've yet to have a problem, slipping or noise. I am completely satisfied with it.

    I'm about three months in on mine and while sweet when new, it's a noisy mother now! Typically need to teardown once a week in order to shut it up. Becoming more frequent. That said, I dig the clean concept, just wish I could figure out what the problem is with mine...

    Mine creaked for 3 months and i ripped it apart about 20 times and was ready to sell it, then Eric at niner sent me an email telling me about carbo-grip, my ISIS BB has been silent ever since. I move it regular to change cogs and its still quiet, i am 100% happy with the BB now.

    I've been curious about the carbo-grip. Where'd you pick it up at? I take my ebb out and "re-Teflon" it every other month or so. I change cogs pretty frequently. Though it seems like a pain in the ass, I still love my SIR. Hell, it only takes maybe ten minutes to do. Can't say I've had any problems with the biocentric slipping. I prefer the ebb over horizontals all day long.

    Mine never slipped, just creaked with every pedal stroke.... it was driving me mental.

    My LBS got me the Carbo-Grip, was slient from that day. I have even got and ISIS BB, Niner said ISIS would be doubtful even with carbogrip.... im still happy 9 months on.

    I initially set up my SIR9 as a 1x9. I installed the EBB per Niner's instructions with the teflon tape. As a 1x9 I could set and torque down the EBB before installing the BB and crank. It worked great -- no noises.

    Then I converted the bike to singlespeed, and thought the Niner eccentric bottom bracket was a bit of a pain. I couldn't get it to rotate more than a few degrees, so I had to remove the cranks, bottom bracket, and EBB, and start over. The original teflon tape was pretty mangled. (As a side note, I was surprised how much rust was in the bottom bracket. I had treated the inside of the frame with frame saver and hadn't ridden the bike that much.) I put some anti-sieze on it this time instead of the teflon tape -- hopefully that will help keep it working and noise-free, and also help prevent rust. I thought of using carbo-grip, but I was afraid that it would keep the EBB from rotating freely to tension the chain. The torquing of the EBB was a lot tougher with the cranks installed. I'm using X0 cranks, and their width partially blocked the EBB bolt access.

    Hopefully I won't have to mess with it again for awhile.

    Exactly. I use carbogrip for both my SS rigs, SIR9 & A9C without any issues, except for the chain stretching on occasion, is there a fix for this

    I'm Going to try some out next go 'round. I run square taper cranks (ENO's).

    I love my EBB. Oh you mean the Niner one? Not sure as I have only used a Bushnell on two Niners - with no creak or slip what so ever.

    Yeah definately do

    I absolutely love my One9 and with carbogrip keeping it quiet i really like the easy adjustment of the BB. After the big reveal of the new One9 it looks like i'll be keeping my scandium One9 for a while yet, IMO getting the new one would be downgrading.

    My issue isnt creaking but slippage, have to re-tighten the chain about every 10 km's. Did the teflon tape thing also. Got so pissed off, now installed with carbo grip, teflon tape and some locktite, god forbid I break a chain on the trail....

    Are you torquing to the rec'd 190in/lbs ?

    Mines torqued to 300in/lbs then a small tweak for luck so over 300in/lbs :

I LOVE my Niners. Rode my EMD to a 1st place finish yesterday. But the SIR9 had to go. It rode like a dream the few times it was quiet.

    I dont have a torque wrench so no idea but I have really reefed on it. Was thinking of just making so the thing doesn't move and buy a white industries hub....

    I'm wondering...How does the number of people whining about the Bio-Centric EBB compare to the number of people that whined about the old set screw EBB. I had absolutely no problems with the old set screw EBB. I'd love to replace my old Sir9 with a Air9C, but I have to admit, the Bio-Centric is what is holding me back. I really do not like to fiddle with stuff at all, and this seems a little to fiddly for me.
    I only ride bikes to fill the time when I'm not skiing.

    Those of you who are getting ham-fisted with your EBB bolt- remember, those threads that the bolt goes into are aluminum. Over-torquing is a bad idea.

    Yep, but losing $300-400 on a frame you just bought because of a squealing BB is worth the slience. I'll take my chance after 1 year of tightening it to that ham-fist tightness, worst that can happen is a new $70 Bio-EBB.
