The front hub is a Normandy so it's not all English but I think it might even be a Canadian-made frame. The bars are new zoom aluminum ones with VO city levers and some cork/rubber grips that I find quite comfy. The brakes are Alhonga dual pivots so the bike actually stops. The rear brake was modified with another barrel adjuster to allow bottom cable entry so it looks kind of unorthodox but it works better than having an S curve in the housing. It's a pretty "sprightly" ride with all the aluminum parts on there.

Nice!

Was this a 3-speed Sprite originally? My guess that not; as they are rare compared to the 5 & 10 speeds.

Very nice old warrior you have there; I have never even had the good fortune to lay eyes on anything like that here in Bicycle Flyover land - ha! Are you going to restore it too?

PalmettoUpstate 05-06-15 11:47 AM

SAME TIRE DIFFERENT NAME? ETRTO is same but tires listed as 650 x 35A and 26 x 1 3/8.
 
I was exploring my options for "bombproof" city tires - especially for the Raleigh Sports type bikes - and I came across something that confused me at the SCHWALBE website.

Cutting to the chase, will the Marathon Plus shown for 650 x 35A fit on standard Raleigh rims or must I use the standard Marathon?

I can't tell from your link. Try shortening it with http://goo.gl to take the special characters out. But if the BSD is listed as 590, then it will fit.

i have a spare AW hub, the only problem with hand brakes is there aren't any braze ons for the cable. plus the stopping power is diminished with the steel rims. hence the 3 speed coaster hub... we'll see i doubt it will fit him very long :)

Hmmm... I don't understand why that didn't work.

Here are individual links:

Marathon Plus, 37-590, Black-Reflex, Wire | Schwalbe North America [Marathon Plus as 650 x 35A]

and...

Another name for 26 x 1 3/8" is 650A. So I interpret the top one you mentioned at 650A & tire will be 35mm wide.

I consider myself schooled!

Thanks for the clarification. [and what is 650B?]

Velocivixen 05-06-15 04:38 PM

650b is a different, slightly smaller size. There's a 650c also, which I believe is having a resurgence among Tri Athletes. You can do internet search & will explain. Look up Sheldon Brown - he provides an excellent description. I'm no expert, but I've built some 26 x 1 3/8" wheels lately so I know that much.

noglider 05-06-15 05:12 PM

Right, both of those tires will work. Velocivixen is right about 650A. Now, I could be wrong, but I believe 650C went out of style. Too bad, because it was good for short women. But this has nothing to do with three-speeds.

I admire your technical expertise and the fact that you don't "have a desk"; can you tell me which tools you have decided upon to do wheel building?

Tools? I scoured CL for about a year. I bought a New in box Park Tool TS 2.2 Professional Truing stand, New Tensionometer from LBS, used but great quality Wag 4 Park Dishing tool.

For the holidays I received a Bicycle Research Nipple Driver & some more sizes of spoke wrenches (Park & other brands). A friend gave me a home made tool of a bent spoke at one end & other end is used to hold nipple to thread it onto spoke when the spoke doesn't quite reach the hole.

I took a 16 hour (over 3 days) wheel building class about 2 weeks ago. I asked for this for my birthday. The owner/instructor of Sugar Wheel Works uses the Schwinn technique for building wheels, where you put all the spokes in at once and go from there. I walked away from the class with 2 fantastic disc brake & dynamo wheels for my husband's birthday gift.

All well and good. But you've yet to ask me about "having a desk"...

Usually 26 x 1-3/8 means 650A. However, Schwinn had a size sometimes called

"26 x 1-3/8"

and sometimes also called

"26 x 1-3/8 x 1-1/4"

These Schwinn tires are actually a slightly different size than 650A and meant for a Schwinn S5 or S6 rim, not a Raleigh Sports/Superbe rim. However, these appear less commonly than the 650A tires. Be warned that you will see that Schwinn size sometimes called 26 x 1-3/8 as well, even though it's a different tire.

Naw, it was a derailleur model, but the little heart-shaped braze-on the downtube was the perfect place to put the fulcrum clip and the braze-ons for the derailleur cable route the shifter cable much cleaner than clamping full-length housing. I built the wheels with 700c rims, the narrow fenders kind of limit the tires to 32mm but it makes for zippy city cruiser. The woman I sold it to is apparently pretty happy with it. I have a grand prix frame I have been building wheels for but I keep passing the wheels along to other projects. Soon I will get my hands on some more 288mm spokes and build it up finally, it'll be a drop-bar three speed. I have a front dynohub built up into a rim already and some old lights that I need to clean up. I scored another dynohub so maybe by the time the autumn rolls around I will find another frame to build up.

I just checked and Terry is still offering a bike with 650C wheels specially for small riders. Actually, it looks like the 650C wheels go on bikes from about 48 cm to about 54 cm. Smaller bikes get 700C rear and some sort of 24" front. Larger get 700C front and rear. Appear to be very nice bikes with Ultegra components. Frames are butted steel made by Waterford in Wisconsin.

I've only seen a couple of the Terry bikes over the years, probably at my first and last RAGBRAI back in 2010. You'll see everything at RAGBRAI including penny-farthings, unicycles, and single speed Schwinns with coaster brakes. Best I can recall, they are nice bikes and go for a market that almost all other makers ignore.

Ooh, I'm sure there's a bunch of people elsewhere on the internet that will school you so much on 650B, you'll practically have a PhD! ;)

As for sorting out "26 inch" tire sizing, of course Sheldon Brown has something to say about it:

26 Inch Bicycle Tires

Yeah I had seen that Sheldon page before but I thought I'd tease out some info on the 650C. In my own wrenching I have only come across the 597's [schwinn], 590's Raleigh etc., and 559's MTB. It's kinda interesting that you have almost 10 CM difference in the diameters of these "26 inch" wheels; that's a lot!

FWIW, 26 inches is 660 MM and assuming an average sidewall height of 30 MM above the rim's edge for lightweight bicycles it would put the Schwinn S6 at almost exactly 26".

So, looking at the Wickedpedia chart, is one to assume that, in order to realize an OD of 26" the sidewalls on the 650C tires, with their 571 ETRTO, are taller than those on the 597, 590 and 584 ETRTO?

Also, since the 590's are a 650B, it appears that the chart Schwalbe has showing the Marathon Plus as a "650" is incorrect as that should indicate a 597 ETRTO if that Wickedpedia chart is correct.

Tire Sizing Systems

Yeah I discovered that rather profound "nuance" early on - LOL. I think it was back when I was a teen and worked like hell to get a 590 on a 597 [schwinn] rim.

Didn't happen and I was pissed. The guy at Western Auto had unknowingly sold me a tire for the British rim size. Or, mighta been my bad by just grabbing the first one I saw that was marked 26 x 1 3/8.

ETRTO? I don't need no stinkin' ETRTO!

Yep. The confusion regarding 571/650C is that the original idea (at least in Schwinn's usage) was a new wheel/tire size for their "middleweight" cruisers". This 571/650C was called 26" x 1 3/4" by Schwinn. And this tire kept the near 26" outer diameter of the tire. Later on (1980s?) the 571 became a "tri" size, but with much skinnier tires, so they don't come near the 26" OD as originally intended.

Actually, 590 is 650A. 584 is 650B.

Marathon Plus, 42-590, Black-Reflex, Wire | Schwalbe North America
And looking at the Schwalbe page about the Marathon Plus (assuming that I'm looking at the same page as you), their sizing nomenclature is correct, as they call it either 42-590 (tire width first, wheel size last), or 650X40A. When they list the tire size this way, the letter comes after the width. Same with other sizes. If you had a 35 mm wide Marathon Plus in 700C, it would say 700x35C on the sidewall.

And to note: that Marathon Plus may be the widest tire size for 590/650A/26" x 1 3/8", at least as wide as the Panaracer Col de la Vies!

And while I'm thinking about it, who is going to Lake Pepin this year? I definitely am!

noglider 05-07-15 01:59 PM

One problem with tire sizes as they are often expressed, and as at least one of the above-cited articles says, is that they were sized by outer diameter of the tire. And only approximately. So for example, you have the 559 rim, the kind we see on mountain bikes. With a fat tire, the OD might approach 26". But with a skinny tire, it will be much less, and if you used a ruler on the rim, it would be around 24". It was a bad way to number the sizes.

If I recall correctly, ETRTO (European Tire and Rim Technical Organization) was subsumed by ISO (International Standards Organization). Yet we still refer to sizes as ETRTO sizes when we use the actual measurements in millimeters.

SirMike1983 05-07-15 02:25 PM

I like that diagram. There's always the dreaded 599mm 26 inch size as well, seen usually on US-made lightweights and roadsters from the 1940s and earlier. They are rather uncommon compared to the others, but no one makes tires specifically for this size anymore. On some 599 rims you can slip a 597/Schwinn tire on and be OK. Sometimes the 597 won't go on though, depending on the rim's profile. These are usually abbreviated 26 x 1.375. The Sheldon site cites them, but does not mention that if you go down the path of 1.375/ISO599, you may not be able to actually get ANY tire for it.

Ha-ha-ha!

Been waiting for that so's that I could pontificate and say thanks...

Here we go...

In life we humans can't avoid encountering the kind of people who can't and won't do jacksh*t but they invariably, as a crude prop for managing insecurity, assume the air of being "an expert" and they have to be put somewhere in order to keep them from fomenting trouble in the streets...

You've met them; maybe, like me, even cursed them at times...

Whether in the military, the local governmental agencies, schools, message boards, etc. you'll find this kind of bird populating the place and attempting to make life miserable for other people.

Now this isn't to say that there aren't a LOT of people in the aforementioned venues who are jam-up individuals and who love the world and it's inhabitants and always try to do a good job. IOW, while they may work at a desk these folks don't "have a desk"!

Does this make sense? Can you think of anyone who is afflicted with "having a desk"?

Even here, at BF's?

A Redneck Dad's Maxims for his beautiful daughters:

1. Don't bring anyone around here and introduce them as your date if they can't do their own brake jobs.
2. Associate with people who can do things and will.
3. Learn how to get what you want from people who have desks.

BTW, I really, REALLY appreciate the precision, polish, and diligence you have demonstrated in your restoration endeavors as shared on this thread.

You, my dear, DON'T have a desk! LOL!

Caio!
