    GT Peace Eccentric Bottom Bracket ... very hard to adjust

    So I guess this is mostly for those of you running Peace EBBs, but I suppose anyone with an eccentric bottom bracket could help out.

    I've had my bike for a few weeks now, and have begun to develop a little bit of chain stretch.

    So, I decided to adjust my EBB before my chain got so droopy it started skipping.

    I unscrewed the two set screws on the bottom of the shell, and tried to move the BB holder. Wouldn't budge. Even with a little 'persuasion', still no go.

    After removing the crankarms on both sides and popping the BB holder out of the shell using my 'persistant persuasion tool' (i.e. the rubber mallet) I applied liberal amounts of grease to the shell, and threw the holder back in there.

    Now, the only way I can spin the BB holder is to apply my BB tool to the driveside BB and turn it clockwise a full revolution until I get it where I want it.

    Is this normal? Are eccentric bottom brackets supposed to be such a pain in the ass to adjust?

    mine was a pain in the rear end also one of the major reason i ended up with a non-ebb frame. i used to use a screw driver or 4mm allen wrench. you put it one of the holes on the bottom bracket shell wrap a towel around the tool and use your crank arm for leverage.

    Grease, grease and more grease... Pull it out and grease it. It get stuck because of all the grit that just sits and drys in it. Pull it out grease it and assemble. You should do this every few months or so. More if you ride in wet environments more often than not.

    When I took it apart last week there was almost no grease in there, which might be why it was so hard to move. It has lots of grease in it now, though.

    They need to make a EBB with seals on it for they wont collect mud. It could be similar to the White industries esentric hub in a way I sopose. Make life a whole lot easier and maintence free or at least not as long or often.

    Yeah. I guess there's a lot of things GT could do to make the Peace better.

    But then it wouldn't be at the price point that it is.

    For example, the frame is a little on the heavy side....
