"Thun" BB - information needed -

Recommended Posts

Has anyone any information on the below bottom bracket?

I cant dig up anything online and I can't recall ever seeing one be it in a magazine or in real life.

Any information (year etc) would be grateful‰

That's one of those weird-ass Northern Europe bb known as a fauber bottom bracket. They came on Monarks and other Danish/Swedish/Norwegian bikes lower end bikes as well as their version of a BMX bike.

The one in the picture is just a little fancier version I believe.

Sorry about the tiny ass pic, all I could find

Edit. Here's a link with some pics that I believe is the same type BB

Yes Matt, it's the same brand - it came with my Thun opc's - I can't remember Thun doing anything 'entry level / cheap'

Yeah it's a weird one, I thought Thun were manufactured in the States though, or is this a seperate Co?

Don't think the Thun crank and the BB in question are related. The Thun BB is probably from the European (German?) company

The bike in the original pic is lower end for sure and has a chainguard on it right?

 

Here's one of their cottered cranks.

I just grabbed that pic off the Internet as it was the only thing I could dig up - I recently purchased a set of Thun opc (currently en route to me) that have the same BB - i thought I'd try and dig up some info before fitting.....it's proving harder than I thought.

Old German company apparently. They only make BBs now apparently. 

But lots of Thun cranks on Ebay and info out there.

You don't have a pic of the set-up that is heading your way by any chance?

R,

It must just be some weird coincidence - I know they have been together (cranks/BB) from day one, 1982 apparently -

Here are the only pics I have until later in the week:

Interesting.

 

I'll backpedal (!) on the Fauber but will still say that is a European Thun BB.

 

Your original picture is from an old European market Peugeot CPX-103 that some British guy was trying to restore a few years back by the way.

That doesn't surprise me, I just 'borrowed' the pic as I didn't think I saved a copy from the sale.

 

I think you are right especially after viewing your above link - it may have been sourced from an anal bike builder bitd that needed to match his kit up.

 

I'm in two minds whether to use it - I'll know more once it's in my hands.

VERY interesting now.

 

Here's a pic of the right side view of the crank of CPX in the original pic.

You should be a PI Rick - great researching bud!

 

I still feel you are right, maybe it was a long distance relationship that just worked - USA meets Eastern Eropean.

 

Can you recall ever seeing that set up before?

At one point Thun (usa) was part of ABS co (Ashtabula Bow Socket.) Plainly seen in the ad that mattes posted. They made the Thun cranks out of a factory in the south east.

Yep.

Just interesting on the whole design with the sprocket retainer/holder and the "squareish" backside of the crank arm being similar on the US Thun and the unknown (German Thun?) crank on the  Peugeot.

 

As far as seeing the set-up before, you mean the chainguard?  And is this set-up coming from Europe, US or locally?

Rick,

 

The crank and BB I purchased are coming from the UK.

 

So is it still safe to assume the BB in question is still low end/entry level?

 

I presume my crank is the USA made 'Thun' and the BB the cheaper European kit with the same name (but completely different companies with no relationship to each other)

 

Strange how these two ended up together...

 

Thanks for your help Rick, I appreciate it.

 

Ben

Hopefully I am wrong but I would say so.

 

I also don't see an American company stamping "51.5 mm" markings on their product for some reason.

I'm still in two minds if this BB 'guard' should be utilised, it's kind of cool and whack at the same time......
