New Database of Bike Tubing Measurements
Holiday Greetings C&Vers,
Wondering why that old bike of yours rides so well? Is it the tubing? Check out this database that shows the tubing specs of actual bikes, as measured by a precise ultrasonic device:
https://docs.google.com/spreadsheets...#gid=523030770
Click the "vintage" tab at the base of the spreadsheet to see many vintage bikes.
These measurements are a passion project from Reed K. of the iBOB, Classic Rendezvous, and 650B Google groups. Reed lives in San Francisco. If you'd like him to measure your bike in the name of research and science, please reply to me via PM.

I assume that the bike would have to be in San Francisco, though?

This sounds like it has great potential to learn and spread information. I hope that lots of folks in SF get their bikes "scoped". Unfortunately for me, non of my V&C bikes or tandems are among the bikes listed.

Yes, it's ideal if you and your bike(s) are in San Francisco, so you can ride to Reed's place for tube measurement. But if anyone really wanted to send a frame to him and pay for return shipment, that might work, too.

I ask cuz I have a couple frames that are probably Accles & Pollock Kromo tubing, similar to 531 but a true chrome molybdenum steel rather than manganese molybdenum steel, and they seem to be a little lighter than 531 frames. Must be pretty thin stuff.
But alas San Francisco isn't happening.

Tube set? That is of minimal importance to me, these days. I do not think that the tubing type has much to do with comfort, or speed, or handling or anything else, except to stroke the ego of the bicycle owner. I do accept the fact that lighter means more competitive, but not more comfortable, or dependable or anything else, again in my opinion.
The best feeling bike, that I have ever owned, built and ridden was not exotic in any way. But the ride quality was stunning and I am so sorry that I was stupid enough to sell that old, entry lever Italian Legnano that I found at the Dump...

Interesting project!
Much can be done with the data. Like overall thickest and thinnest frameset. Some graphs would be nice, easier to comapare and see the full range.
What precise ultrasonic device (brand, model, etc)?
