Was all original, tyres had all but perished so I installed fresh ones and swapped the front wheel for a spare alloy one I had and added Kool Stops so it will stop.

Bike does not seem to have any miles on it at all.

What tires do you recommend for the Twenty? I'm still riding the originals on mine. Did you swap out the front rim, or the whole wheel?

Schwalbe Marathons come in a 20 inch size although you cannot run them at their max pressure on the stock rims... at 65-70 psi they ride pretty nicely and this is within their operational range.

Am using some BMX tyres that I had at hand which are for urban riding so they have a nice roll out and ride quality and again, am running them at a slightly lower psi to balance the ride quality with speed.

Swapped out the front wheel as I had a spare that is spaced at 95mm to fit a Raleigh fork... if one does nothing else to a Raleigh Twenty, changing the front wheel to alloy and adding better brake pads is the best thing you can do to improve stopping.

Will eventually lace new rims on to the hubs... CR18 rims are a good choice for this as they have a nice vintage look and are very well made.

It has been a bit difficult to find a 3 speed on CL at a reasonable price in the local area (The Bay area seems to have an inflated market). My local second-hand bike shop has a very sharp Dunelt I'm considering (an SA 4 speed hub, too), and I may buy it if the DL-1 doesn't pan out. A nicer DL-1 came up on the 'bay last week, and it was only 2 hours away; I waited for bidding to start, but the seller became impatient and put a "Buy it Now" price of $250 on it and it was scooped up before I could make an offer. I'm patient, though. The internet has made it easier to find one, and I've got time.

Surprised there isn't a tutorial out there on fixing a Dynohub...

The Dunelt sounds pretty cool. A 4 speed, eh? That would be nice, though I know you're in a similar environment as I am--straight and flat for the most part. Single speed country! I hope that DL-1 comes through for you. Like I said, I've been a big fan of those Tourists and would love to find one myself at some point. That would be a fun resto project and that ride is so classy. Good luck and hope to see you posting pics of your new bike soon. How sweet it would be to ride that DL-1 along the bike trails in Old Sac!

Aaron, would you have a quick explanation as to why my dyno hub rotates when I turn the light on?

Zumkopf 09-06-11 04:36 PM

I had a 28" Bobby's bicycle. My wife insisted I sell it so we could rent a smaller moving van. Should have sold the wife instead.

Jedge,

From your description it sounds like you may be missing a lock washer and or the cones are too loose. My Superbe (looks a lot like yours) is buried about 5 bikes down at the moment. When I get a chance I will pull the wheel and check the order and number of the pieces. IIRC you need to run the right hand cone down tight, then adjust from the left hand side. Here is a blog post (not mine) where someone has taken one completely down and has a nice picture.
And here is another source for information on dyno hub rebuilding.

Aaron :)

From this brief description I'd assume you have a battery backup for the dyno hub generator. Is that correct? Also, does the hub incorporate permanent magnets, or does it use rotor and stator windings?

If so, it is most likely due to the fact that electrical generators are motors run "in reverse". That is, if the shaft is mechanically driven, they will generate electrical power on their electrical terminals. Alternatively, if they are electrically driven on their terminals, they generate mechanical motion on their shaft.

A diode in the line could prevent your battery from discharging through the generator when the hub is not spinning.

Of course, I could be completely wrong on all of this. :)

I didn't see any sign of a battery backup on his bike...

Battery inside the headlight case?

Perpetual motion machine? :)

That's a real big help. I'll check and adjust those cones, maybe after I take a look at the blog post you sent me. I really appreciate the extra info as well as your own opinion.

Nope, no battery. That I know of at least. :)

Mike Mills 09-06-11 08:39 PM

Oh well, I tried. :)

LESS talk, MORE pictures. All this talk is ruining the beauty that this thread has been for me in the past.

Anyway, finally got a cool one that fits well. :)

Check it out!

That is really a nice one Banjo. Can you tell it's "Made in England"? ;)

Such a funky stem, huh?

Sixty Fiver 09-08-11 12:53 PM

A few more miles on the Twenty today... figured that on what is going to be a very hot day one will not want to be racing but rather, pootling along and enjoying the sunshine.

Am pondering taking my Sports out on Sunday for the 5th annual Tour de Perogy which is a 140 km pootle...

My new find and project. A Raleigh Tourist. 1981 1 on the hub. It will give me something to do this winter. Also some pick of two others.http://bikeforums.net/attachment.php...hmentid=218025http://bikeforums.net/attachment.php...hmentid=218026http://bikeforums.net/attachment.php...hmentid=218027http://bikeforums.net/attachment.php...hmentid=218028http://bikeforums.net/attachment.php...hmentid=218029

I purchased a Raleigh Prestube rack off eBay. It did not come with the connection hardware. It is not a show stopper. I can fabricate something but I would like to get the original type. If anyone has an extra they would like to sell or trade, or knows where I might find the connection hardware I would be grateful.

I just used P-clamps on my daughter's Sports:

That Tourist is very nice...great pick up! Doesn't the full chaincase indicate that it wasn't originally imported to the US?

olddurace82 09-09-11 10:23 AM

That could be. I asked the story behind the bike. The young lady I purchased it from said an older English gentleman had brought it to the states with him. She found it in the garage of an old house she purchased from him.

Interesting solution, but I am going to go the more traditional route. I plan to use two bars, say 3/4" by say 1/8" and drill holes for the bolt. I will sandwich the rack between them and I will cut up some old tubes to prevent any degradation to the paint. So rack-bar-rubber-seat stay-rubber-bar-washer-nut.

Rolled in to the co-op today to see a beautiful 1964 Raleigh Sports, ladies model in the yard... everything looks to be there and what is most notable is that it is finished in the rather uncommon silver with white panels.

Do not think this one will last long and I may have to give her some love this morning.

olddurace82 09-10-11 06:53 PM

Any pics?

Rats. I had thought about coming in but my weekend's gone sideways - badly.

I missed out on a Sports for my girlfriend a couple of weeks ago. Maybe I should stop in tomorrow.

The bike did not last 24 hours... a nice young lady (a friend of a friend) came in and snapped the bike up.

Ah it figures. Thanks for letting me know - saves me a trip.
