Help me understand this 50's Raleigh bike...and help me find a part..
Hi
I bought this bike late last year and the seller described it as a "1957 Gentlemens Roadster". I thought it looked cool and I wanted a project to restore so I bought it.
It has balloon tyres and balloon mudguards (tyres are 26 x 2 x 1 3/8)
It has drum brakes front and rear that were cable operated and a Sturney "AB" hub.
The gear roller is steel but not brazed on.
It has the Bottom Bracket oil cap on the drive side (right hand side)
The serial number on the seat tube is CN 44620 which doesn't match any of the conventions I can find online. The front hub is dated "3 52" and the rear is "52 9" so I'm fairly confident that it is a 1952.
Is this a DL-1 Export? (I am in New Zealand) It has really fat rear chain stays and straight dropouts at the rear with a tensioner (not the angled type I have seen on some Raleighs)
It has the holes predrilled for the "rockers" (fulcrums? - I'm not sure what they are called) for rod brakes so I have ordered the parts to convert her back to rod brakes. Someone had blocked these holes with self tapping screws.

So far I've stripped and repainted all the steel parts and I have parts at the chromeplaters now (rims, cranks, seatpost) - I'll post some "after" photos shortly.
The only part I am missing for the rod brake conversion is this part in the pics below. I'm not sure what it's called. Anyone know where I can get one? It's the part that is fixed to one side of the fork and and pivots when you operate the front brake

With 26" wheels, it's not a DL-1, but something more like a Dawn Tourist, but that had conventional EA3 wheels, and you have something else (and I'm not sure what). As you suggest, what was imported to NZ may differ from other markets.

If it originally had rod brakes (which I don't doubt) and it now has drum brake hubs, then those hubs are not original; so that throws your 1952 date out the window (sorry!). So there is also no need to consider the rims original; it could well have been a Dawn Tourist with EA3 wheels.

I also wonder if those are the 26 x 1 3/4 " rims found on delivery and trade bikes, irrespective of the markings. (571 mm bead) It might be hard to source new tires.

I find this bike intriguing. But more so after reading clubman's 26 X 1 3/4 rim hypothesis. At second glance, those balloon tires do appear to be much larger than the typical 26 X 1-3/8 tire and there is still a substantial space left between the fender. This would also explain the need for drum brakes as the normal rod brake would not reach the rim. Regarding new tires, a Schwinn S7 balloon tire also has a 571mm bead and might fit. I believe Kenda still makes this tire.
I am looking forward to the after photos and any more information you uncover about this bike.

Thanks for the replies so far.
Here are some more pictures before diassembly (apologies that some of them are of the bike upside down which I took mainly for reference of where fastenings and cables were located for when I put it back together).
You can see how wide the chainstay is compared to most Raleigh roadsters. It looks about twice the normal width.




The tires are 54-571
I plan to use rod actuation onto the exisiting hubs

I agree. Usually when we hear the words "rod brakes" we assume the kind of brake where the rod activates a stirrup that pushes the pads onto the inner edge of the rim, rather than the sides of the rim like a caliper brake. On your bike the rods activated the drum brakes. If that's the case, your hubs (and your whole wheels) are probably original.

Thanks for confirming the mystery wheel size. I seem to recall some 1930s English roadsters being fitted with 26 X 1 1/2 (650B) wheels - SirMike's Hercules roadster comes to mind - but this is the first Raleigh roadster I have seen with 26 X 1 3/4 (650C) wheels. It should give a nice, smooth ride.

The rims are at the chrome-platers now but I will measure the width when they come back. Is the 1 3/4 simply the width from edge to edge (44mm)?
I was able to pick up some CST tires locally in 54-571 size. They are not ideal aesthetically because they have a kind of hard "shoulder" to them rather than being round and balloon like. They will however allow me to get it back together and find the ideal tires later.
The bearings and crank went it in last night together with the headset cups and the bolt-in seat stay. A new B66 black saddle arrived in the post yesterday. I'm really just waiting for the chromed parts and the rod brake parts before any real further progress can be made.
I noticed last night that on the top of the front fender where it is recessed to fit between the fork legs there is a stamped "B". I assume this indicated "balloon" but I'm not sure.
The luggage rack has "Midlands England" stamped on it
Does anyone know what that finned thing at the front hub in the photo above is? It was held onto the spokes at 4 points with very small nuts and bolts. My first thought was something to do with electrics but the dynamo is on the back wheel. My second thought was that maybe it's something to do with disipating heat from the front hub? Any guesses?

^^ The dynamo is on the front wheel- isn't it? There is a generator mounted on the rear as well.
The square thing looks like a heatsink and part of the mechanism for the front brake.
I doubt the "B" is for 'Balloon' unless the Brits had a completely different idea of what balloon tires were all about. Balloon tires were usually wider, but I am an American so balloon tires may have a special meaning here.

Several points to consider here. Sosogo, the 26 X 1 3/4 is simply the old English method of describing the ISO 571 rim/tire size. The Sheldon Brown website has a wealth of information on tire sizing. Unlike today, the outside diameter was always nominally 26 inch (or 650 for the French) and as the tires progressed from narrow to wider/taller, the rim diameter became smaller to compensate. As Clubman has noted, I have only seen this wheel size mentioned in Raleigh catalogs for the rear wheel of a Raleigh delivery bike. Most every Raleigh Sports sold in the USA had 26 X 1 3/8 wheels/tires (EA3 or 37-590). Salubrious, while I agree that it is doubtful the "B" stands for "balloon," the OP's bike indeed has the same size tires as most Schwinn middleweights, which is why I find it unusual and interesting.

I think the "heatsink" was an old school mileage counter that had a toothed mech. I'm sure I've seen that one before.

I'm sure that's correct. There was a gear that meshed into that ring, which spun a cable which ran to the speedometer/odometer mounted to the handlebar.

Cool, and cool bike; I was trying to sort out how how I could build something like this- didn't know they had actually made it...

I still would like to know which model these bikes are. Yes, they are DL-1 variants but I'm sure they were designated their own name and model number. Now there are three on BF and the latest one has drum brakes!

Every time this beautiful bike is posted, I feel the need to put up a picture of mine as well...

It makes sense that the machines were built for a market that was marginal in the road department. These machines look like they might not be too bad on single track as long as it did not require a lot of steering.

This is a cool bike. I know there's a distributor in Canada (babac) that sells 571mm tires too but I would imagine they are the same CST tires you found. A friend has an old CCM that has the same tires and they were the only ones I could find in that size that are anything close to balloon tires.

You can see it in the pic, the white cable has the little gear on it.

Also some pics of the bike as it currently is while I wait for the chromed bits

Ummm, I really should have noticed this before, but are you ordering a rod-brake handlebar with the hardware already attached? I don't think that the normal levers that came with your bike will work with rod brakes.
The handlebar rods on mine (a '39 model Raleigh built for Sears Roebuck) don't appear to be removable and easily replaceable - it looks like once they come off, they will be very difficult to get back on, but, I admit to being too chicken to try on a hard to replace handlebar.
