Already have a bike you like , but wish the top tube was longer?
determine how much you want, then cut the top tube longer

If the Top tube is still to be horizontal, miter angles would reflect seat and head tube angles ,

the miter of the downtube angles at BB and bottom of the headtube would change..


I built a 58 seat tube , 60 top tube bike in the 70's , the front wheel does feel lighter ,

Because it's further ahead of the CofG of me in the saddle..
