Trickstuff Exzentriker Eccentric Bottom Bracket install for singlespeed MTB

[@treimar]

I could get horizontal dropouts for my bike but I think I will go this route instead. I don't like to faff with horizontal dropouts, fenders, brakes. I think It's much simpler when the rear end is just normal.

They should have made some sort of tool retainer as done when unscrewing an SS freewheel from rear hub by fixing it in place with a hub bolt. A hole in the tool with another pinless buddy on another side, bolted together through the bottom bracket, would make a great job.

Yes I know..... I’ll hold the phone round the other way next time. And yes, too close so going to try bigger cogs at same ratio.

Did you get an answer regarding the position of the screw/locknut? I can't get my head around the instruction and my exzentriker seems to slip...

[@familyhistory1983]

Did you ever work out your slippage problems? Any insights/hints? I have just received one of these and would welcome any advice before I embark on fitting.

@@familyhistory1983 I figured out it was actually my bb shell turning loose. So just watch out you install it so that if there is a pull on the exzentricker it tightens the shell.

Just received one of these so grateful to see your video - thanks. Also been pondering the instructions and wonder if you agree that the 'quadrant' section may be implying that depending on which quadrant you end up in, you may have to swap the external eccentric part from one side to the other in order to end up with the screw/locknut fixture being correctly orientated as pers the instructions such that forward motion of the crank/chain/belt further tightens on the eccentric? Did you ever get a response from the company? Is this what they said? Although I can understand the rationale and its importance it would seem to add another potential faff in that although you might strike it lucky first time, you may equally have to set things up, find you have got the 'wrong' eccentrics on each side and so have to swap them over. Would be interested to know it others agree or have any insights (or better German ?!)

[@jamiemyates]

They did come back, and agreed that the instructions needed rewriting. But they didn’t really explain when they did respond. That said, my chain stains only allow me to use he 3-6 or 6-9 o’clock positions. I’ve now used it in anger, and it’s fab. Occasionally need to adjust it to take up the chain stretch. A quick knock on the pins with a dot pouch frees them up.

How is this EBB holding up? Are you happy with it? Is it worth the extra cash over a tensioner? Thanks!

[@jamiemyates]

All good, definitely.

[@jamiemyates]

Holding up well. Adjust every now and then with chain stretch.
