I had the same question when I was looking for forks to build up my bike... did some research and there are so many bullshit stories, I even found a video of a guy timing himself doing laps with different offset forks.
I think in reality it doesn't really make much difference.
How dumb/stupid/dangerous is it to put a 52mm offset Pike on a Stumpy designed around 44mm. The other option is a 41mm fork and a 4 month wait.
or increase the travel to 150 and get 42mm offset Lyrik?
