At the risk of starting a stats nerdfest....

They didn't actually sample 100 riders and record what kit they were using. They recorded which forks 100 riders were using, then recorded what shocks the [u]next[/u] 100 riders were using, etc etc.

So the overall sample size was larger, but you can't really draw comparisons between the groups.... ie: forks/shocks, shocks/frames or wheels/tyres, because the populations were different. For example 3 people had DVO Jade Coils in the shock categories. Those 3 people could have also had DVO forks - but they weren't sampled for forks.

Also, depending on how quickly riders were "cycling" through uplifts - some of the populations might overlap..... ie: the riders sampled in each group were neither unique or identical. So in some categories there may be correlations between groups, but not all. For example: A bike (frame) might ship with an particular OEM component, but because your population is neither unique or identical, you have no way of knowing if that resulted in a corresponding number of riders using that component.

Not sure if that makes it statistically more representative or not.... we would need some stats nerds for that ๐Ÿ˜€

and I thought you had been here for a while ๐Ÿ˜‰ never let the integrity of the stats impact the discussion until at least page 5

I did wonder if somebody had snapped their Evil in the queue

Evil Undead 0.5%

until I spotted they had counted 200

3 Gearbox bikes is interesting

Interesting to see that the wheels had gone from 90% 26" and 10% 27.5 to 50% 27.5" and 49% 26" in a year!

And clips up from 16% to 27% and female riders from 16% to 22%.
