2 things. first, my math, that is used to power diamondback’s calculator, has you at closer to 650mm x 480mm.
How did you come out with this?
I just used the DB calculator.
If I put 182 of height and 82 of saddle height I get 625mm X: 476mm
If I put 182 of height and 90 of inseam I get 627mm X: 479mm
Thx
