Bleumels on a Twenty

 

Following up  Sheldon Brown's advise on the subject of fenders  ,  for my latest 1972 Raleigh Twenty rebuilt I installed SKS Shiny Black SKS 20" Bleumels.
I like to share the result with you.

At the front fork I used 17 mm clips to secure the fender stays


For the rear fender I used hollow spacers and drill a 5 mm hole in the top of the fender

A clearance with the tires of 17 mm makes a good fit around the wheels


I'm very pleased with the result and hope this is helpful for you

What about a drum brake hub or a drum/dyno hub?

EDIT:

Sorry about the premature  post.  Here is the message I had in mind:

 

Steel rims on a Raleigh Twenty is of particular interest to me.  I've acquired a couple of 20’s here in the UK and the frame is a very good size for my daughter, who would be using the bike in London traffic.

But, my concern has been braking, particularly in wet conditions.  I presume that even with the improved brake blocks, braking in the wet is still a major drawback?

 

I’d already identified the Tektro Long Arm brake as an upgrade but felt for safety I would need to install alloy rims.

 

Any observations?


Brake performance upgrade

 

Not happy with the brake performance with the classic brake pads on the steel 451 steel rims I have upgraded the brake pads with Kool Stop City Brake pads (KS-CTB).
The better options for correct toe-in adjustments did the trick and now I found the brake performance is very satisfactory.


On the left the old mount and on the right the new brake pad is shown. It's a reasonable economic and easy to perform upgrade for better brake performance.

Re: Does anone know what this part is?

 

It's the Sturmey Archer Indicator Guard HSL 711.

It is very low priced and generally available. I get them for  € 1,71.
Besides protecting the chain it looks nice and keeps your trousers clean ..

Oh, I didn't know that. Now I do! 

Ooo I may see if I can find it on Facebook :)

Thanks for your help,

There you go! 

I am US based so the bikes over here are a bit different.

The hinges are the height of simplicity. They are basically a couple of relatively flat plates welded on the end of the tubes with a threaded pivot bolt and a lock bolt. A touch of grease on the bolt threads and they work well. All of the Twentys that were sold in the North American market appear to have been folders aka Shoppers, we also have the smaller 406 diameter wheels versus the 451 diameter that is standard in the UK market. There are a few other notable differences. 

There is a UK based Facebook group for Twentys that is very active, they plan rides, meet-ups and have parts swaps. I am part of that group too.

Also.. FYI 

From now knowing that the proper name for the gear chain is the 'toggle chain', I have now discovered what this plastic part is called. (I told you I don't know much about bikes but am willing to learn!)

'Indicator cover/ guard'

Very cheap so I have purchased one!

Hi Aaron!

Thanks for the reply :)

Ah okay, its good to know it's not crucial. My frantic googling can now stop! haha! 

I am from the UK.

I will have a look at the different lighting options you mentioned and see what I can find. 

Also, nice folding Twenty, curious to know if its still easy to 'fold' it or due to age its pretty stiff?

Re: Does anone know what this part is?

Hi Charlotte,
Welcome to the group! The plastic part that broke is not critical to the bike, it mainly serves to protect the end of the toggle chain if the bike happens to fall over on that side. I have roughly 20 bikes with 3-speed hubs and only one of them has that part on it. I have no clue what it is called.

What country are you located in? It will help in locating sources of items for you.

There are several options for lighting, you can get a vintage dyno set from eBay, or purchase a more modern version. The easiest would be a wheel driven set, something similar to this one. However, I would not purchase that one. I would look for a vintage Union, Soubitez, or Basta. If you want a dyno hub the Sturmey Archer GH6 would be an option, however, it would entail building up a new wheel. 

On my main Twenty, I have a Sturmey-Archer AG (3-speed dyno) combination hub in the rear. It powers modern Busch and Muller LED lights.

Does anone know what this part is?

Hello! 

I have never posted in such a forum before its quite a foreign concept for me. I am also very unknowledgeable about bikes. I'm only 21 but have long had a fascination about 'old' things. My Dad is big into restoring old Triumph cars and I was always on hand to help. So my Raliegh 20 is my new project. I have always loved Raleigh's vintage bike and also have an old Chopper! 

Anyway... To my question. 

I was wondering if anyone knows what this little plastic part is that covers the chain for the Sturmey-Archer gear hub is called and also if it is crucial? The one on my bike has deteriorated and when regreasing the front handlebar bearings it just fell apart. and I know that  Sturmey-Archer gear hubs are tricky to fix if they go wrong so would like to avoid this! 

I am also quite keen to get Dynamo lighting for my bike, preferably NOS or maybe used,  so any tips or advice on this would be great! 

Thanks so much! :)
Charlotte 


Thanks for the Add!

Evening folks

Thanks for the add

Looking forward to have a browse of things here and get some ideas for my own 20s. 

Here is one of my own custom projects I’m currently working on. 

The scheme is based on the Raleigh Dyna-Tech Team livery. 

Thanks!

Aaron, 'very impressed with your SA experience. There seem not to be many other SA enthusiasts, or if not enthusiasts at least users, online. Do you know of any other groups/websites where SA- user types cluster?

Re: Sturmey Archer AW Hub Service Intervals #poll

I can't find the reference article at the moment, however from what I gather when SunRace moved all the hub manufacturing machinery from S-A to Taiwan after the sale they found out it was completely worn out and they could not produce any working hubs. This led to pretty much complete re-engineering of the entire S-A hub line up. I know there were some issues with the early production 5-speed hubs from the new factory, but those have since been corrected. I have a 5 speed with the 90mm drum brake laced up in a wheel, but it has yet to go on a bike.

I have several NOS AW and AWC hubs from the late 70s, none have ever been laced up. Out of the 15 + AW/TCW/AG/AWC/S3C equipped bikes I have only one has been a problem child. I only have two AW equipped bikes that have seen any real mileage, the 1970 Sports Standard with over 50k miles on it, a 1972 Raleigh Superbe with ~8,000 miles of riding. I have a 1971 Raleigh Twenty but the original AW hub was swapped out for a late 60's AG which has been trouble-free for over 3,000 miles. When I acquired that hub it was full of crud and dried oil. I filled it with kerosene and rode it for a bit, then flushed it again with kerosene. Pulled the insides out checked for issues, rinsed it in lacquer thinner to clean out anything the kerosene had missed. Greased the bearings with cheap brown grease and use non-detergent motor oil in it.

All of the newer hubs supposedly don't require lubrication between servicing and I have no clue what the service intervals are supposed to be, however according to Shimano they should be done every 3,000 miles or once a year if used for daily commuting. I would suspect that the new SA hubs are similar.

 Hi Aaron and thanks for sharing your experience..

The "poll" template is rather restricting and doesn't allow for comments and so I'm glad that you took the time to describe, in a few sentences, your AW experience. I found your reference to a Q/C problem notable in that I am aware of others, admittedly only a very, very few, using late U.K. production to have similar experiences . I wonder if the shift of production to Taiwan has lessened or eliminated the problem.

Re: Sturmey Archer AW Hub Service Intervals #poll

In my case, I guess it depends on the hub. I have one that is from the early 70s (un-dated shell) with somewhere north of 50,000 miles on it. I would check and grease the bearings a couple of times a year when it was being ridden regularly and add a few drops of oil once a month. I finally opened it up back in early 2000 just because. I did end up replacing the pawl springs because they seemed weak. I have another hub that is dated 1972 that has been a problem child from the first time I ever rode it. It has less than 5,000 miles on it and has been apart several times. I think the issue has been corrected, finally. There were a couple of parts in it that appeared to not have been made to tolerance and caused issues. 

I am of the opinion that if it ain't broke don't mess with it. As long as the hub is working and will more or less hold oil I will ride it.

Sturmey Archer AW Hub Service Intervals #poll

I've been quite curious about the service-life of the venerable AW. And so, this poll has been created in the seeking of a sharing of members' experience. I am posing the question:  How many miles traveled before the hub needs to be removed from the shell for servicing operations which would include the replacement of pawls, pawls and pawl springs, dog clutch and spring, bearings and cones, and chipped or worn gears and pinions?  

Thank you for voting. Results will be available when the poll is closed.
