I am trying to source an outlet for bottom brackets made by censored Germany. I am looking at putting it in a Raleigh Twenty apparently it works and they do that sort of thing to older bikes in Holland my web searching has got me zilch!
Much appreciated Gary Knight

My Carlton is the only thing keeping me going.
The Raleigh Twenty will be okay. At least it will be a fixed folder.

I probably should have just ordered a Swift folder.

I need a folder twice a week. didn't want a Brompton.
The bottom bracket threading on Raleigh Twentys is Raleigh's proprietary 26 tpi size. The shells are also rather wider than standard, approximately 76 mm. If you wish to upgrade a Raleigh Twenty for modern cotterless cranks, you have 3 options:
* Have the bottom bracket shell re-threaded to take an ISO standard 24 tpi bottom bracket. This works, but the threads are not terribly strong, because the diameter is the same, so there will be some missing threads. (The shells are not thick enough to tap out to the larger Italian size.)
* Re-use the original 26 tpi cups with a long cotterless axle. "7" series bottom bracket axles are made to work with 73 mm "oversized" shells, and some of them can be made to work in the Raleigh cups.
* Use a cartridge bottom bracket with Phil Wood 26 tpi retaining rings. I'm told that it is possible to use Shimano UN72 bottom-bracket cartridges with the Phil Wood rings, if a Phil Wood bottom bracket is beyond your budget.
If you order a Phil bottom bracket for a Twenty, you should be careful to order a long-barrel bracket (made for a 71-75 mm BB shell), or tightening down the mounting rings may not be possible.

DESCRIPTION Brakes
it's so easy to accumulate isn't it? i have the bob jackson (god i love it), the fuji and the condor acciao. i can't bring myself to get rid of the fuji, i'm even preparing to 'lend' it to a friend so i can clear space but get it back afterwards.
i take it you've seen sheldon's 20:
someone on londonfgss.com did a fixed shopper conversion. there's always one bike polo.

I've got a couple of original Claud Butler frames, a bilaminate from the 40's and a lugless from very early 50's. An Ephgrave and a Wearwell track frame. A No.1 Condor track frame which needs new ends from the 50's and i think a PT Stallard. And an unknown 50's bike equipped with very old Campy Gran Sport 5 speed derailleur and Gran Sport Pedals.
I was thinking of getting a Dawes Kingpin but I don't think they are as strong as the Twenty?
So might stick with the Twenty.
I want them all and then see others that I appreciate and have to stop myself. Might sell off the vintage stuff. I have fixed hubs from the early 50's still in the packaging.
I am reluctant though and started out by coverting just one spare bike. Watch out Peejay you might get bitten.
the photo needs to be on a website, either flickr or some other.
then click the Img tag, then paste the URL, then click Img again. it should work.
for example, this is a URL: http://farm2.static.flickr.com/1140/131 ... a81477.jpg
you can get the URL by right clicking on the image and clicking "copy image location".
URL with Img tag either side:
