TVT Angles?

[BigFoz]

It's a spreadsheet, but it can calculate formulae if you put them in. Happy to try and do it if someone can provide the formula (Rienster?)

All help is much appreciated, folks!

Edited as I copied the data from the TVT table incorrectly. Image attached shows the formulas I used for seat and head angles. I am not sure on the wheel size TVT used for 700c based on the fact they quote 571 for 650c I assume tyreless 700c.
Hopefully this is right, but don't flame me if it isn't




H I CH F Seat Head Wheel
470 118 55 40 75.5 71.6 571
480 120 55 40 75.5 71.6 622

Re: Re:

Thanks for posting that link. It's maybe just my night shift brain, but I can't see anything about the TVT frame angles there . . :?

There isn't, you'll probably need to plug all the other numbers in somewhere and work back to the angles.
