Let's offroad / mountain bike / mtb / ride dirt

^ yea exactly, although since I shared the plans of MTB build with some MTB friends they want me to join them do some trails which should be fun. My main fear isnt a suspension fork its the lack of gears ;)

I plan to get Schwalbe Big Apple in 2.15"

I rode plenty of trails on the surly, fully rigid SS and it was fine. You've just got to keep pedalling!
