Rotating BB on Niner SS

[tunariaan]

Hi gents

I don't run a chain tension er and if i can i would like to go without one.

Currently i have the original niner bb but it seems to be slipping with the right torque setting and event putting special putty in there doesn't work

It was obviously designed for normal gear riding and not to put that massive torque through it.

I get about 300km out before i have to re tension.

I had my bike serviced and sorted and after 3 days of the Tankwa trek my chain was too slack.

How can i sort this problem out?

Thanks for your help

What niner is it?

What niner is it?

Yeah would love to know as I am converting mine to a SS.

If it is any with an EBB you should have no movement on that if torqued correctly, you could always get a new EBB from them, their new verison which may be better.

The original Niner EBB slipped. No matter what I did it slipped. I now run gears

 

Apparently the new EBB 2 (biocentric 2) fixed the problem - it has two tensioning bolts instead of one.

I had the same issue, and it drove me MAD!!!!!!!

 

Tried the plumbers tape, copper slip, carbon assembly paste et al, and NO LUCK.

Eventually stumbled onto this, the buschnell ebb.

Fitted mine, with the required sleeve for the Niner ebb diameter, and all sorted.

Here my post from a previous thread;

My comment more about the Niner EBB;

 

I have a NINER Air 9Carbon, and ABSOLUTELY in love with my bike.

The Niner EBB gave me grey hair, in the sense that it creaked and slipped.

The maintenance on this killed me, as I needed to re tighten after every ride.

With the Niner EBB I tried all 9 different methods of fitting, the carbo-grip option, the carbon assembly paste option, the plumbers tape option (this one, I got an even thicker plumbers-tape, and that was the closest I got to a slip and creak free EBB)

 

Now, I got tired of the hassle, and after some hours of research, I made contact with some guys in the US.

 

Bought my new Bushnell EBB about a year ago, fitted with a shim (for the niner's shell diameter) and a endless care free, creak free, adjustment free riding.

 

They have 2 models. I opted for the "retro" older one, as then the expanding force pushes out along the full shell vs the full EBB circumference, vs just the "shoulders" of the skeletonised "featherweight" EBB option.

 

Loving it, and now I have a TRULY "maintenance free" bike in my SS.

 

I hear the EBB II is also ok, but cannot speak from experience.

 

My ebb currently lakes me 20min 2xer year to remove, clean, service and re-fit.

 

LOVE the low maintenance and simplicity of my SS

 

Happy hoopin

I have the Niner Biocentric II EBB and love it.

 

One piece of advice though - tighten each of the two allen key bolts a few times. I found out during a race that if you tighten one then the other that the first one needs a retorque. Alternate between the two a few times to ensure a tight and maintenance free fit. The Biocentric II also has a dead end hex hole to tension the chain while you tighten the first allen lock bolt - great idea.
