28x1 1/2 Tubulars for 1938 Rollfast

I have a customer who wants me to gussy up the bike his grandfather bought for his father. Mechanically it is rock solid. What it needs is 2 new sneakers. Problem is they are 28 inch tubulars and I have only found some red ones online. Anyone know of a vintage shop or site I could visit that might have black walls, or better yet, white walls? Size needed is 28 x 1 1/2.

Are you sure they are 28", or just 700c by another name?

I know my Vittorias are labeled with the 28" size, as well as the 700c designation (not sure about the 622 of the top of my head)

Tubular tyres only came in 700c although some are marked as 28 inch for other markets... double check the erd on those rims.

Finding a wide tubular in this day and age that looks right on a '38 Rollfast might be a challenge... and am also wondering why a Rollfast would have tubulars.

Well now, I guess the rules have changed since I last visited in aught- six, or was it aught-nine?

They are labeled 28". And they are indeed 1 1/2" tires. I have glued them on several older rides over the last 25 years or so.

Not sure why a Rollfast would have tubulars, but the bike does. The rims are not even wooden, but steel. Very odd indeed. The bike was bought new here in town by my customer's grandfather for his son (my customer's father) in 1938. My customer even has the original bill of sale. The bike was ridden, but taken care of decently being that it was owned by a boy. and yopu are right. Finding 28" tubulars in a 1 1/2' size is tough. I have located some red ones ( the guy calls the color "cinnamon"). My customer would prefer black ones.

Your request prompted some research on my part. 28 1 1/2" are a valid size also known as 635 or 700b. Indeed the Vittoria's are labled with 28" contributing to the confusion. Sheldon does have a good description of the sizes: Tire Sizing Systems. 622 is 700c.

Such a challenge! I don't know if Larry at the old bike shop: https://theoldbikeshoparlington.com/ can help or not. He is most interested in 1800's bikes but might know of a source.

Thanks so much. I will check his site out and better yet try to get in touch with him. Again, thanks.

I am familiar with the 28 by 1 1/2 / 635 as this is the English oversize wheel that you will find on bicycles like Raleigh Tourists but am not familiar with any tubular tyres in this size.

European tyre makers often put a 28 inch by x by x marking on their 700c wheels which creates a lot of confusion... they are still 622 tyres just like a 29'r tyre is also a 622.

Bottom line is that the rim needs to be measured to confirm it's size and make sure it is not running some totally obscure / proprietary tyre size.

@sizty Fiver, fair enough. I would defer to your experience and knowledge. What was unclear to me from Sheldons site was if the size also applied to tubulars. I was surprized to learn there are other than 700c sizes produced in the past and don't know enough.

Well, if they are 622, I presume a road tire is desired?

With the recent interest in riding dirt roads I thought for sure there would be something like that but the closest I see is the Clement LAS. It's not overly knobby so should ride OK on roads. Kinda pricey at $110, however.

A-ha. Challenge Strada Bianca comes in a 30mm, nearly 1.5" - Tan wall or black wall.

Don't you have a plain old modern tubular you could do a test fit with? It doesn't even have to be a perfect fit, just snug - I can't imagine your customer is likely to ride the bike in a manner that might roll the tire.

IDK why not look for & buy/build wheels to uses tires you Can find easier?

28" is the common Sew Up tire .. that 700c Clincher rims try to be interchangeable with .. training wheels ..

The "tubulars" you speak of sound like "single tube" tires ( pre-ballon era), they were common on Pre-war bikes, early ones had a chain pattern as below. They are expensive, over $100 each. The colored ones are solid tires for display only, for a true pneumatic tire, call Harper Machine in Dunbar WV 304-768-1147.

Chaching! You beat me to it.
Try over at www.thecabe.com. There are a couple of sources online, and one has some grey cyclocross tires that are almost wide enough to look right. Or you could lace up some English 635 rims to some American coaster brakes.
Singletubes are indeed 622s, but the rim is so wide, nothing modern will fit.

Correct.

Tubulars from 1938 are exactly the same as tubulars from 2014, there is no difference.

In addition to the 30mm Challenge tires, there are 32-33mm Dugast Pipestrello tires and I believe FMB has a 30mm Paris/Roubaix tire. All of these have a tan sidewall.

The Vittoria EVO XN is 32mm and has a silver (gray) tread and black sidewall. But I think they stopped making those.

Thanks so much for the phone number. And yeah, I know how expensive they are.
