28'' tubes?

[Ed Deas]

So my touring bike came with continental tires that say (28 x 1 3/8 x 1 5/8) & 37-627. I just moved from Orlando, FL to Charleston SC and can't seem to find tubes for my bike. The guys at the LBS in orlando always had 28'' tubes in stock, but the guys at the one in charleston said they had never even heard of a 28'' tube. Any good websites to buy from?

627 ?? are you sure it's not 622 (which is 700c)?  627 is not even listed in Sheldon Brown's tire size web page.  A search for "627" on biketiresdirect.com comes up empty too.  There is a 635, and 622 is sometimes called 28".  But for tubes which don't have to be exact, a 622 (ie, 700c) tube will work just fine for a 627 tire, as long as it's fat enough for the 37mm-wide tire.

yeah.. you're right. it's 622. thanks man.

www.cyclocamping.com has a large selection of Schwalbe tubes and tires.

The shop in Orlando didn't really have 28" tubes, he just recognized what you really needed.  Quoting from Sheldon Brown's web site about 700c (ISO 622) wheels; "In northern Europe, this size sometimes called "28 inch.""

Just to make things even more confusing the current MTB wheels advertised as 29" are also a 700c rims and tires.
