Quick question on stack & reach between two bikes
Moderator: robbosmans
Take a look at the two bikes below. Why do they have almost identical stacks when bike A has a taller HT by 15mm?
Bike A
HT: 17.5
HTA: 73*
TT: 56.5
STA: 73*
BB drop: 6.6
Stack: 57.5
Reach: 39
Bike B
HT: 16
HTA: 73*
TT: 56
STA: 73*
BB drop: 7.0
Stack: 57.4
Reach: 38.5

Aside from the valid points already made. Some manufacturers are not very good at calculating reach and stack.
There are a lot of brands where I have to check their calcs before importing into my database (including some of the big brands)

look at the side on shots of the bike, the fork crown on the Ridley is almost down to the brake bolt, on the Bura it's a lot further above. So while the HT on the Bura is significantly shorter it has a lower BB and a taller fork. Which is why stack is a better measurement for comparisons.
Also cyclenutz - who's bad at calculating stack and reach - and what do you actually mean by calculating? It should be a pretty basic physical measurement, but a difficult to impossible calculation from a traditional geo chart.
