Blank Grizzly 3's bottom bracket height, I'm trying to figure it out. They are saying that it has a 43mm bb drop. What does that workout to in regular bbh mathematical terms? 11.5, 75 etc ?
Thanks in advance boys !

Huuuh, on about every bike there’s some kind of BB drop, but in bmx bb is over the axles so a 11.5” BB is 1.5” over the axles (3,8 cm), plus 10” for a theorical half wheel (wheels are closer to 21” nowadays with fat tyres).
1.7” is about 4.3 cm so I guess the bike have an 11.7” BB height.
