Details
With the Excentriker we have another nice innovation part for your bike. An eccentric bottom bracket for standard frames! Fix to standard frames and brings the possibility to adjust the chain tension (for gear hubs and single speed). So you don’t need a chain tensioner, adjustable drop outs or tandem bottom bracket any more. The Excentriker is easy to install and brings you a smooth optic on your bike! Fit with single speed cranks with 24mm axle (like Shimano HollowTech II).
Runs on two 6805 bearings. 37mm OD - 25mm ID - 7mm Width

How easy is it to replace the bearings ?
By Roger Dunn
20 Nov 2020
Do they need to be installed with a hydraulic press or can they be tapped in with a rubber mallet. Thanks
SJS Customer Service:
You would need a bearing press to do this accurately.

Frame and BB compatibility
By Ramil
29 Jun 2020
Hi, I have a Trek Cruiserliner bicycle with 3 speed hub.
The frame's BB is threaded and 68 mm in length. I have square tapered BB.
Could you please clarify certain points:
1. Is Exzentriker compatible with the frame?
2. Will I have to replace square tapered BB and cranks?
3. How much adjustment will it give? I plan to move the wheel as close as possible to BB and then adjust with the Exzentriker. I suppose I can add a half-link for single speed chain, if it exists.
4. Is special tool absolutely necessary to install it?

SJS Customer Service:
Yes, this fits 68mm BSA threaded shells.
You will need to be using a 24mm axle chainset, such as a Shimano with Hollowtech2.
We do not have exact adjustment measurements.
Its possible to fit /adjust without, but it makes life harder.

Hi, can I use this on an old Giant Defy frame (English threaded BB) ?

I was using a Shimano Tiagra RS500 english threaded BB on my Defy that I now want to convert to a single speed commuter for Winter.
SJS Customer Service:
Yes RT
Hi, can these be used on early Moulton APB? Thanks

SJS Customer Service:
No, I don't think so, the bolts that secure the rear suspension behind the b/b look to be wider that the bottom bracket shell and too near to it (so this will foul it. RT 27/04/2020

Can I use this with a BSA 68mm cromoly 39mm shell.
By Age MacKenzie
12 Nov 2019
I am wanting to use this with a 597 cromoly shell 39mm BSA. I am slightly worried because your dimensions mention 37mm. Will it work. Also fitting a Shimano Alfine FC-S501 crankset. Is this compatible?
SJS Customer Service:
Hi there,
unfortunately, as we have not tested this we cannot say for certain I'm afraid.
Thanks.

Are the bearings replaceable
By Shane
25 Sep 2019
I'm also guessing with my disc trucker this means I can completely get rid of my chain tensioner?
SJS Customer Service:
Yes, two 6805 bearings. 37mm OD - 25mm ID - 7mm Width.
Yes, this removes the need for a tensioner.
Thanks - 30/09/19

How much adjustment available?
By Ian Ezzi
18 Jan 2019
Hi, just considering using this to adjust BB drop on a frame, how much adjustment appears to be available? I'm guessing you can rotate the bearings so they sit at the bottom of the BB shell, plus the thickness of the threaded portion of the cup?
Thanks
Thanks
SJS Customer Service:
Based on manufacturer website:
"Deviation: +/- 3 mm; plus halflink. Halflink fits 7spd, 8spd and 9spd chains. Halflink width w/o bolt 6.6mm"
This portion with a thread on it is 15mm.
Hope that helps.

This is not the intended design, but I cannot see why it would not work!

Will it work on Marin San Rafael?
By David Callow
30 Dec 2017
Rohloff fitted and currently using Rohloff tensioner. Standard square taper bottom bracket with 46 tooth chainwheel. Bottom bracket shell too small for usual EBB. Before Rohloff fitted it had an SR Suntour triple crankset. The single chainwheel was a straight swap.
SJS Customer Service:
Hi there,
This should work but we have not tested it ourselves so there may be some unforeseen compatibility issues.

Inside BB Protection
By Rod Butler
07 Oct 2017
Is there a plastic open ended cup that fits both inside rims of the EBB to prevent moisture build up in side the BB housing?
I think Shimano has some thing like it.
If not are they available as a spare part in a similar size BB?

Hi,
Unfortunately it does not come with a centre tube like the Shimano bottom brackets. We don't know of any that would be compatible with this BB either I'm afraid.

Question Re Rohloff Chainline
By John Arnott
27 Mar 2017
Hi there - I am very keen to explore the purchase of an exentriker for a Rohloff hub that i am using. I have a question about achieving a 57mm chain-line - Could you suggest what crankset i might be able to couple to achieve a 57mm chainline?
SJS Customer Service:
Hi,
We don't have exact chainline measurements for most cranksets but we do know that if you wanted to fit a Shimano MTB style crankset that with the ring in the outer position then this would give a suitable chainline.
Thanks.

Type Of Crankset?
By Mark B
10 Mar 2015
What would you recommend as a single chainwheel (say 46 tooth) crankset to go with this, probably to run with an SA S3X rear hub (120mm) on a frame with standard British Standard BB shell?. Do you need to buy the bearings as an extra item?
SJS Customer Service:
Hi,
Any crankset with a 24mm diameter spindle will be suitable for use with this, so any Shimano set and any Shimano compatible cranksets that are designed for use with external bearings. The bearings are already included in this product so there is no need to purchase them separately.
Thanks.

Shell Size
By Andrew

I am thinking of fitting this to a Genesis Croix de Fer 2015 frame which has a standard 68mm BB shell with a view to fitting a Rohloff hub. Do you think this will fit a standard 68mm British thread BB shell? Also the Rohloff needs a dropout spacing of 145mm?
Thanks,
Andrew
Thanks,
Andrew
SJS Customer Service:
Hi
Yes the Excentriker will fit a bottom bracket shell of 68mm however all Rohloff hubs are spaced to 135mm only, we wouldn't be able to advise as to whether you would be able to have the frame adapted that would have to be something that you would need to speak to a frame builder about.
Regards, Jamie
