On-line tools for bike nurds
The "Engineers" thread made me think that there is enough of a nurd-ish group here that might enjoy these bike tools. Only for the truly obsessive.
The best general bike website: https://sheldonbrown.com/
The best bike gearing tool: https://home.earthlink.net/~mike.sherman/shift.html
Another good tool to be used in combination with the above: https://www.kstoerz.com/gearcalc/compare/
A good bike fit calculator: https://www.competitivecyclist.com/za...LCULATOR_INTRO
What you need to know about modern steel frames;
In terms of overall tensile strength, here is the order from strongest to weakest of common bike tubing steels;
1. Heat-treated air hardened steel (Reynolds 853, Columbus Foco, TrueTemper OXPlatinum)*
2. Heat-treated CrMo(Tange Prestige HT, TrueTemper Verus HT Reynolds 725)
3. Cold-drawn air hardened steel (Reynolds 631)*
4. Cold-drawn 4130 CrMo(Reynolds 525, TrueTemper Verus, Tange Prestige/Infinity)
5. High tensile steel(cheap dept. store bikes, cheaper bike shop bikes)
* Air-hardened steels actually gain strength in the weld area after welding, but not along the whole tube.

A good site for Weight Weenies 
https://weightweenies.starbike.com/
And a spreadsheet for weighing every component on a bike.
https://fairwheelbikes.com/c/updates-...plication.html
(By selecting your desired components from dropdown lists you can build a virtual bike or custom
wheel set and see what it’s finished weight would be along with notes about the specific components).

Silly as it sounds, a lot of people forget about this resource:

I've no Campy components, but I'm pretty sure they have an analogous site.

I built it up with Ofmega parts and it was just a beautiful ride to see. And it was also a 63cm. The sorryest thing I ever had to do was to sell it so I could get my machinists tools shipped to San Diego from Dallas. I fell in love with the red and yellow Trek 970 frame as soon as I saw in in the bike shop and would probably cry if I saw a photo of one now.

Yeah I don't quite know if the 970 road bike was just a little stiffer ride because of the matl or possibly guage difference in the stays or something. It also had a sloping fork crown. It wasn't really uncomfortable but I could kick it out from under me standing on it on a rain soaked road, lol.

This is my 1978 Trek TX 900 in a 25 1/2 inch size, also made of Columbus SP. With a supple tire and moderate air pressure, it provides a firm and responsive ride;

My Trek 970 is still being built up. I like the Trek frames made with Columbus SP. I find many steel bikes to be a little flexy, Columbus SP solves that problem!
This is my 1978 Trek TX 900, also made of Columbus SP. With a supple tire and moderate air pressure, it provides a firm and responsive ride;

Yeah mine was a 62, not a 63, now that I think about it. And that was from c/l to top, not c/l to cl. It just wasn't as tall as that 900. Columbus SP is really great for bikes that tall and especially when climbing. The 970 was an all out racing bike and those frames were hand made, not on a computerized jig fixture.
The 500 that replaced it with in San Diego is grey metallic with red bar tape and pump...a lot more subdued in appearence but slightly less stiff and more subdued is just about right for me 30 years later.

This is the granddaddy of speed/power calculators. Like jrl's speed/power calculator, except it has more capabilities to calculate for other types of bikes than just a generic upright.

Being new to bike repair I am always looking for articles on " Repairing Bikes " . I have to admit that there is still a lot I have to learn like all the gear ratios and different charts that there are for different things. But right now I just try and learn what I can as I need it. I do have a couple of the bike repair reference books and get a lot of information from the internet as well. So I learn as I go along.
