I made this simple stack and reach calculator because I couldn't find one that suited my needs online. Hope you find it useful!

I put it up on blogspot cause it's free. http://bb2stem.blogspot.com/

Please give it a try and let me know how I can improve it. :up:

I tried it and it seems to produce correct answers, which is the most important thing. I changed the values to make a common comparison - a frame with all of the same geometry, but just one size larger. I added 20mm to the head tube length and 15mm to the horizontal (eff) top tube length on the larger frame, but left everything else the same. When it came to the stem setup, 20mm more spacer was used on the smaller frame. The reach came out to be 15mm longer, just as it would be, using a TT length comparision.

Thanks for testing it. Wondering if I should include a trail value as well?

Yes, the spreadsheet runs on javascript.
