So. The frame has a steeper head angle than some, it also is shorter than some, it also has a lower bb than some(level). I was wondering how much affect a longer fork like a 420 Knifen has on this bike. I can see pros and cons to longer forks. Andrew, you are getting a 400mm fork for your pure? So, that bike has a 71-72 degree headtube angle, and a +10 bb(?), anyway, if you put a shorter fork on I think it will become closer in geo to say a cous with a longer fork ...kinda sorta maybe perhaps, your opinion please. Mr Phunder, do you like your bike as is or would you consider a shorter fork? You are taller than most and that makes a difference I know. Any complaints though? thank you Im just curious. Ive been thinking about stems and forks and so on and I was wondering if I should use the 420 with a low stem or a 400mm fork with a higher stem. To make me impartial I have at the moment a nice 105 x 10 stem that I think would compliment a 420 fork much better than a 400- atleast for me. If you made it this far, thanks; I tried not to write like a scatter brain but thats hard for me.
