| Hi all, after much searching I find I now have to turn to you folks as the experts for hopefully some assistance with my dilemma!|
Walking thru a swap meet last year, I spotted an old CCM bike I fell in love with. All it needed was a bit of TLC, which it has now had and will hopefully soon be on the road. I just need some tires… I did not suspect this would be such a big issue. I had ordered two sets of tires from my local bike shop before I realized there are definitely different rim sizes out there….. Can any of you good folks get me pointed in the right direction for a set of balloon whitewall tires for my new pride and joy?
Here are the details; the original (worn out tires) have stamped on the side of them the following: 26 x 1 ¾ x 2 – 650 x 50C (oversize 26 x 2 fits 26 x 1 ¾ rim F 12) Made in Holland, Parragon with a V in a circle.
I also measured the rim and the inside measurement at the shoulder of the rim is 1.015 and the overall outside measurement is 1.50, with the closest profile I can find to that is a Schwin S7 I think. Also the overall outside diameter of the rim is 23 inches.
Well any advice and help on what and where to find tires would be really appreciated... and where the heck is that letter that notes the year hiding? I can't find it!
Many thanks, Bruce
| I have a green Speedster with a serial # of F991638. It came with 24 X 1 3/4 tires. also with a rack on the back. can anyone PLEASE tell me what year it is AND if those are the right sized tires. I'd like to convert it to 26 in. tires and rims. is it possible? thanks |
| If it originally came with 24" wheels, the 26" wheels won't fit.|
Since one the the tire dimensions is 1 3/4, I'd guess those are the original wheels.
| According to the charts on this site, your bike was made in June of 1959. Your 24 inch S7 wheels have a greater diameter than non-Schwinn 24 inch wheels, but I doubt if it is enough to allow you to substitute 26 inch. It wouldn't hurt to try though, you never know.|
| Gordon's response made me go back to|
again. We miss you, Sheldon! Mr. Brown does not mention S-7; only S-5; and he does not mention 24x1 3/4.
However-the difference in radius between two sizes he does list, the 24" S-5 (547) and the 'decimal' 24x (507), is 3/4 of an inch, whereas the difference between 24" S-5 and standard 26" mountain rim (559) is about 1/4" radius. I give you a fair chance of success with 26" mountain wheels if you use smallish slicks.
Gordon, It's about time somebody published a clear explanation of Schwinn's 'S' rim designations, perhaps with the dates each was used and sizes. It won't be me- I'm confused by it, and always refer back to the above site. Sheldon lists S-7 as 26x1 3/4, S-6 as 26x1 3/8, and S-5 as 24x1 3/8, but I'm sure I've seen Schwinn OE tires labeled 'to fit S-5 or S-6 rims ...am I dreaming? What do you say?
| I wish that I felt confident enough to write a Schwinn wheel size chart, but I'm afraid my knowledge is limited as well. Here is what I do know about the infamous Schwinn "S" wheels. The S2 was available in 20, 24 and 26 inch and they took standard size tires. The S7 was also available in 20, 24 and 26 but required 1 3/4 width tires made specifically for S7. The S5 and S6 came in 20, 24 and 26 and required the same tires, 1 3/8 inch made for Schwinn S5 or S6. I know I left out some things, such as the S4, but I don't want to put down anything I'm not confident is correct. |
| That's excellent. Thank you. |
| I have a Schwinn 27x1 1/4 rim, with a narrow Knurle and guess what is clearly stamped on it? S6!|
| See, that's what I'm talking about, Gary. We're making progress here: apparently S-6 comes in 630 (27"), 597 (26x1 3/8) , and maybe 571 too? (schwinn 26x1 3/4?) - as well as 20s and 24s!|
Everybody check your Schwinn middleweights - we should get a list of what years which rim series were used. We can figure out when S-6 morphed into S-7 maybe... where's Schwinnderella? Where's Mark bunch-o-bikes? These guys oughta have this already...
| My 1965 Schwinn Heavy Duti has the single gnurled S-7 rims w/ 1 3/4 Goodyear black wall tires.|
| My Scwinn unicycle marked S-7 had 24 in. whitewalls. The tire was also actually marked unicycle on the side.|
| I've rebuilt a number of New Departure (D) hubs and I know the inner hub, bearings, and other parts get grease, but what about the Disks. Does anybody know the "approved" method? Should they be oiled before assembly or greased. Thanks. john|
| The original literature that I have from ND states that it only needs 20 weight oil. Whether or not that still holds true with today's advanced lubes, probably not. |
| would like to know how to tell year of iver johnson bike. it has 2 speed hub and shifter on cross bar.thank you for any info|
| the ones from the 1930's may would have inch pitch, "skip tooth" chainwheel, sprocket and chain. The cross bar may have another "arched" cross bar under the top straight bar. The wheels may be steel clad wooden rims with tubular tires (no tubes inside) if from the 1940's or later may have steel wheels/ rims but also may have inch pitch drive system. paul|
| thahk for reply. do you know how i can find exact year it was made? and value? i think 2 speed hub is rare|
