looking for? I miss my
According to sheldonbrown.com, tire sizes such as "27" originally measured the _outside_ diameter
of the tire. But, different tire widths made those measurements inaccurate, so now we go by
inside diameter, 27" is 630 mm, 700c (which is a french name that has nothing to do with
millimeters) is 622 mm.
For a wired-on tire, you are looking at something like 270grams for a very good tire. For a folding
tire (and be sure your rims are hooked in order to hold onto the folding tires), you can get a 250
gram tire.
1. www.harriscyclery.com has some excellent avocet (IRC) racing tires (27x7/8, about a 23 mm tire),
folding, slicks, maybe about 220g, new old stock. Only appropriate if you're small (160 lbs?),
or for the front wheel.
2. panaracer pasela comes in wired and folding versions, and panaracer is original equipment for
schwinn (LeTour tires) and panasonic bicycles of the 1970's and 1980's. Available in 27x1, 27x1
1/8, and 27x1 1/4.
3. I have purchased some nice cheap 27x1 1/8 tires from performance
bike, they have them with kevlar belts, and without.
4. Other possibilities include ebay for limited production runs of IRC tires.
I'm assuming you're looking for something better than $7 tiawan and thailand 27x1 1/4 monster tires
- these are easily available at kmart.
