ConsNot the highest quality EBB on the market.
ProsCheap - fits my bike
Perfect fit for replacing the eccentric BB in my Charge Grater 3 2014. In fact, seems to be identical to original part. Good price compared to alternatives i'd looked at. My original one had ceased (possibly due to lack of grease) and was a pig to remove, but now i understand how these work, will be able to maintain and hopefully not have the same issue in future.

Great product, easy to fit and slotted into my Charge Mixer 11 perfectly. I like the way it secures itself by pushing outwards and does not rely on the crude mechanism my old eccentric BB holder used whereby two self-tapping screws held in the frame penetrated the BB by drilling a small hole in it. I used grease when installing it and so far it's silent and squeak free.

It is slightly smaller in diameter than the "Eccentric Bottom Bracket Insert Taiwanese" also sold on this site which was a fraction too wide for my bike.

Howe much offset does this provide?

My rear BB is all the way forward, while the front one is at 6 o'clock, does a quarter turn provide enough length to take out over segment from the rest chain?

I have Fsa with BSA thread, ang the BB shell is 53.95, does it fit perfectly?
Hello, I'm afraid we cannot confirm this.

I understand it works for the cannondale BB30?
03 Apr 2020
I cannot see how, the BB wouldn't fit in a BB30 frame, and a BB30 bb would not fit this.

What's the inside diameter ?
26 Mar 2020
I'm looking for a 54mm / 68mm EBB with an inside diameter around 35mm (to fit a mid-drive motor) would that one fit ?

What's the minimum clearance between the inside diameter and the outside diameter ?

The diameter of a BSA bracket is between 33.6 and 33.9 mm

Is it ok for my 2016 CANNONDALE BAD BOY 1 ?
28 Feb 2020
This has a 54mm OD, so if your BB shell matches that, it should work.

Thanks - 02/03/20
What type of bottom bracket can I use with this?
23 Feb 2020
This is BSA thread, - For use with bottom brackets with a 68mm shell

Is this compatible with the Charge Grater 3 (2015)?
03 Sep 2019
We simply would not know, we have never sold or dealt with Charge. Contacting CSG would be the best option.

Can this be used with Raven Sports tour
14 Aug 2019
The exentric BB insert in my 12 years old Thorn Raven Sports tour has lots of indentation from the grub screws, is this product a suitable replacement? If not which is the correct Thorn eccentric BB insert and cartridge bearing.
No, if the indents are now causing trouble, you have a Raven Mk2 Sport Tour so you need to order Thorn Eccentric Bottom Bracket Insert - Fits Raven Mk2 Sport Tour / Catalyst / Enduro / Sterling / Twin Tandem (SJS Cycles part number : 9053)
Will this work with a 2000ish cannondale 1fg?

We do not have the original specification of the bicycle and could not confirm this without seeing it.

Use on a Cannondale T2 Tandem 2013

Is this the same bottom bracket eccentric unit that was used on my 2013 Cannondale T2 Tandem?

Cannondale eccentric bottom bracket 68mm shell
25 Sep 2017
Is this the eccentric bottom bracket used on a Cannondale trail SS 29er? I need a replacement screw as I've round mine off! Jason

You should be able to use this without an issue.

Can I use this with a Viking Serengeti?
15 Sep 2017
Can I use this with a Viking Serengeti? It has a large tube size. What measurements do I need to take to check?

Unfortunately as we have never sold your bike we have no way of knowing if this will fit it or not I'm afraid. This eccentric is 68mm long and 53.8mm in diameter.
