27 inch tires make a comeback
"When Steve Flagg reviewed his inventory reports recently, one item
jumped off the page-27-inch tires. "We were totally unprepared for the demand in 27-inch tires," said Flagg, president of Quality Bicycle Products. "Wayne D. Gray, vice-president of KHS/FreeAgent Bicycles, noticed the same trend. "We're seeing a lot of demand for them. It's people taking their old Schwinn Varsity out of the garage and to a shop for new tires and a tuneup."

" They could always convert their bicycles to ISO 684-mm (aka 650B) instead. 650B is ISO 584 mm (not 684) bead diameter which is a considerable jump from the 630 mm of the "27 inch" size. Conversion to 700C (622 mm) is frequently feasible, but hardly economic for most owners of an old Schwinn Varsity. It is an encouraging trend though to see that many are taking the old bikes out of storage and putting them back to use. And this should lead to continued availability of the 27" tires I have on our tandem. Ironically, when I built the wheels for it many years ago I deliberately chose 27" instead of 700C because of the greater availability of tires at that time. |

Have you missed all the discussion about Grant Peterson promoting the ISO 584-mm size? I don't think even Grant advocates conversion of frames made for 630 mm and long-reach brakes to 584 mm. Doing it for frames made for 622 mm and short-reach brakes is bad enough, but at least it's frequently rather straight forward. |

A neighbor hauled out an old Schwinn and asked how much it would cost to get it up and running, and after I got over $200, she decided to look into newer technology. Plus, it weighed about 60 pounds!

I think the equivalent 26 inch was an S-6. You can still get these tires, but they are hard to find. Plus those rims are likely to be steel. |

I think the equivalent 26 inch was an S-6. You can still get these tires, but they are hard to find. Plus those rims are likely to be steel. Schwinn and their proprietism (proprietarity? proprietariness?) I'm up to my neck in salvaged alu-alloy 27" wheels. Many are in practically new condition, and some bear those lovely Suzue one-piece hubs. I dunno if they're interchangeable with old Schwinn wheels though. Oddly enough, we don't get to see many Schwinns here in Vancouver BC. Most of our bikes (that are seen actually in use on the street) are of Canadian mfg or imported from Japan. And the occasional Raleigh or Peugeot antique. Those inexpensive IRC 27x1/4" tires are good enough for workaday use, and readily available in Canada from Mountain Equipment Co-op and other enlightened suppliers. Anyway, a vast quantity of '70s Bike Boom imports from Japan are still in service here, and I expect they will be for decades to come, as long as replacement parts are available for them. It's unfortunate that so many USA'ans are so deprived of these Japan-built beauties (mostly Sekines and Apollos,) many of which sport wonderfully sculpted lugs and other interesting design features. For example, my early '70s Sekine mixte has a handlebar that looks like a GMO experiment between MTB flat bars, North Road bars and moustache bars. But it's actually quite ergonomic. It also has Shimano's One-Key-Release[tm] crankset, where instead of a crank puller, you just need the appropriately sized allen key. I've previously mentioned its Front Freewheel System[tm] which allows a rider to change gears by backpedalling while stationarily leaning against a pole and waiting for the traffic light to change. At any rate, 27" wheels are not dead yet. Nor should they be. The only thing wrong with the size: 27" is, it's in Imperial rather than metric units. And y'know what? I don't even know if 700[C|D|whatever] is in SI units -- the One, True Metric System. I even now derive pleasure from the ol' green-gold spackle-ish Apollo paint jobs, even though they are a bit '70s Kitch. At least it's more aesthetically appealing than shag carpet, shag haircuts, panel vans decorated on the inside like bordellos w/ CB radios, and wide lapels & ties. cheers, Tom -- Nothing is safe from me.
