"When Steve Flagg reviewed his inventory reports recently, one item

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.
