# Zeda 80 Kit Options: Heads and sprocket size.

I work pretty slow, and am distracted at present messing with my Schwinn .

Nottin' wrong with that. Plus some time to collect quality or custom parts add to the time.

I kinda thought so Jerry, thanks for doing the math for me...lol.
26\36 = 27.5\38 = 29\40

So would 27.0 = 37 tooth? JOhn
Do a true diameter check on the tire. Hold the wheel perpendicular to the ground. Hold a level on top of the tire and get level. Measure from the bottom of the level to the ground; that'll be your true diameter.

For example my 26" Kendra 838 tires true diameter is 26.25"

27 inch on a similar bike I have here (1980 Schwinn Traveler with 1.25"tire) measures @ about 26 &7/8" from ground to top of tire.

700c Mavic wheel on a Trek measured to almost exactly 26" from ground to top of tire--but this was a narrow 23 Bontraeger racing tire.

700mm ÷ 25.4mm = 27 9/16 so I'm going to assume you're talking about the rim

No, I measured from the top of the Tire to the floor.
Tire is a 700c 23. Here is a link on the rim type that I have:

I think the 700c refers to the tire size. John

Sorry to repost late in this thread, but I ran across this link for various sprocket sizes that looked like a good price (\$10.99-\$15.99 ) with free shipping:

Multiple Spocket Sizes.

Not sure about the quality, but they list the 38 tooth option discussed above and several other size options.
