    which EBB - Bushnell or Carver?

    I am looking for a clamshell-style EBB for my SIR9. The "awesome" 2-piece Niner EBB just does NOT do it for me - it creaks so loudly I can't concentrate, even with the plumber tape trick, etc. Yes the sides of the shell have been sanded, blah blah blah.

    I am looking at 2 EBB types - Carver Bikes and Bushnell. Carver is cheaper, but I don't know anyone who has used one. I have a friend who uses a Bushnell and loves it.

    Any experiences, good or bad, with either of these?

    Oh by the way, anyone wanna buy a Niner EBB, used, CHEAP?

    Thanks,
    Eric

    I put a Bushnell in my One9 because of the same problem you had. That biocentric creaked like an old rocking chair (garbage!). The Bushnell seems to be doing the trick. Some tiny creaks now and then, but it's reasonable. Installation is a greasy mess and I anticipate taking it out to clean and re-lube will be messy, but I'd say it's worth it.

    I also am willing to sell a Niner EBB, used, CHEAP...

    Never heard this problem with Niner before.

    Have you tried rubbing the EBB with a lucky lucky chicken bone?

    I have a Bushnell - no problems, no slipping, no creaking!

    Never "heard" it before? You must ride with loud headphones. Otherwise, you'd think there was an old rocking chair right behind you if I was riding near you.

    Intrestingly enough, I got my Biocentric when they first came out. The install instructions at that time were pretty simple, basically face the bottom bracket shell, install, and torque the bolt down to 120 lbs. Since then they've revised the intstructions to include every trick in the book, including plumbers tape, bevelling various surfaces, and now you crank it down to 190 lbs!!

    I'm still happy with my Bushnell, but maybe next time I take it apart for cleaning I'll try the Biocentric again with the new instructions AND the lucky chicken bone. Thanks!

    I'll cast a vote for the Carver as the lesser of EBB evils. I've tried two Bushnells and they slipped, creaked, and bound the bottom bracket bearings significantly. The Carver can be set so it doesn't slip and doesn't bind the bearings. It will ultimately start to creak, but it takes longer to get there than the Bushnells did. And since the Carver is cheaper...
