Looking for some real world reviews, how's this thing's trail manners? Do you feel like a sluggish walrus trying to crank hard on non-steep trail sections to keep speed? Does climbing with it make you hate life and think about injecting? Or is it rad? Thinking about it for my 2015 Spitfire. Current DB Inline is becoming a maintenance nightmare, may ask Cane Creek about upgrading to either the DB Air or Coil CS.....
