It will fit with the stock drivers (2.86 pitch) with no other mods.
Don't believe everything you read on the X3. Try one or ride one and then give your own opinion. I ride in Cascade concrete and I wouldn't have any other track.
The X3 is a game changer IMO.
Man the opinions on the X3 are just crazy to me I have never heard such different reviews on any product in my life, people either absolutely love it or absolutely hate it. Wish I could ride one once
