    Tubular steel rims??

    I was looking at this spec sheet for a '78 Schwinn Traveler and noticed that it describes the rims as "tubular" steel 27 inch-ers. That's surely a misnomer, right? Did tubular rims ever come in steel, or did they go straight from wood to aluminum? And weren't all tubular tires 700c?

    From Sheldon:

    Schwinn also caused some confusion because it often referred to "27 inch tubular rims." In this case, the adjective "tubular" refers to the way the rims were manufactured, not to anything unusual about the tires. Schwinn "tubular" rims were made from steel tubing that was rolled into the shape of a rim cross section. The 27-inch size takes normal 630 mm clinchers.

    while on topic of tubulars-
    For years, inked on the sidewalls of Vittoria tubulars 23 x 28. Goofy Italians trying to please Americano's. Why not simply note as 23 x 700C ?

    They're trying to please the wacky northern Europeans who call them 28", not us.

    Sticky and totally tubular technicians.

    Squeezed the very last out of an old tube of glue. Phoned four LBS to see if they have glue or Tufo tape. Could care less and I use both type. But only ONE shop stocked it! At least it was for aluminum rims but jeez. I go to pick it up and the service tech ask me how many wheels I'm gluing? I replied for now, two. He gives me 4 tubes of glue!!! LOL. Say's they use TWO per wheel and they never come off!! WTF?????


    Granted I do have a few more builds with tubulars in the werks, and with mastic being such a hot commodity 'er lack of, I did take another tube. Should last me for the next decade. Cheer's

    Yup, they're still doing it. Fresh off the boat from Ribble of England:

    Similar experience here. The LBS across the street didn't have any, and the first guy I talked to there didn't even know what I was talking about. "Glue your tires on the rim? Whaa...?"

    The bike shop uptown is run by an ex-racer in his forties, and he stocked it, but also had a younger employee who never heard of it. I'll have to admit; five years ago I never heard it either. Then I stumbled across a website subform called "Classic & Vintage" and ...

    So 28" is the same size as 29" and both are smaller than 27". Makes perfect sense!

    And 28 x 1 1/2" is bigger than 28", 29" and 27".

    And 24 x 1 3/4" is not the same as 24 x 1.75".

    That interesting measurement difference gave me grief when I was 9 years old.
    Why was this tire not fitting? 2.25 is the same as 2 1/4...

    Schwinn's "tubular" steel rims came in many sizes. Here's a cross-section cutaway photo.

    As this thread seems to taking a life of all things vintage tubular, anyone know when textured brake surface first appeared (specific to tubular rims)?

    Probably nobody who knows is still capable of typing.

    My first set of tubular rims was a pair of Nisi marked additionally with "Moncalieri" (means "rims?"), which were installed on a Cicli Rossignoli I bought in 1969 or 1970, and the parts on that bike were supposedly unsold stock from the mid-'60s. Those rims had texturing. So the technique goes back at least to 1965 or so. Since wooden rims still had their uses in that time frame, perhaps texturing goes to the beginning of aluminum tubular rims?

    This being the case, people with questions about vintage tubulars could find answers to nearly all the question on the thread "totally tubular."

    I wish the Mods would re-sticky it, or make it clear where a sticky index thread is.

    I don't know about tubulars, but Schwinn used rims with knurled sides on the 1960-'61 Continental. I believe they were Rigida Chrolux. You can see the knurling in this pic of a '60 Continental:



    The knurling is called out in the '61 dealer catalog page:



    I believe that for '62 and later Schwinn used its own S-6 rims, which had flat sides.

    +1 with Scooper , they are formed from a section of steel Tube , so Tubular, but using wire bead tires ..

    multiple definitions to Tubular ask a Old Surfer what "Totally Tubular" means for another..

    Rims for Glued on Tires have been formed from aluminum tube for a long time..

    ^Term used above 'knurled' is another good description. Early 60's seem's about right as well on that Continental with Rigida clinchers. I've seen only in photo's the Clement clinchers from late 1950's having the textured sides.

    But going back to my curiosity, what of tubular rims having it? While I've been digging thru the Velobase archives, haven't found anything early and more specific to 1950's period.

    Thanks Metacortex and Road Fan. (Btw: where is the totally tubular thread?. Certainly should be and re-named STICKY Tubular thread)


    Anyways, here's pics of the rims in question of age. Older S.Champ decal. Supposedly are NOS yet need some finishing and deburring work. Anyone have thoughts on what age they are? Thanks
