Alot depends on what type of riding you do the most so you can get the most out of your choice. I myself have 14/52 as I ride 90% off road can still go 60 no problem. I ride pavement to get to my riding area here at home or trailer my bike if going over I90 to ride Eastern Washington. I feel the sweet spot for my setup is 45-50, can cruse all day at that speed on the pavement, but no problem going 60 to get where I need to go as well. Love the 52 for dirt because I don't have to shift as often, can cruse in 3rd-4th gears most of the time on the fire roads. I did not go up in the front because it's a PITA. If I did go up in the front for any reason I would being going up to 55 in the rear. I use my bike to get to some out of the way hunting spots that can get rather tricky sometimes. Hope this helps alittle. Just depends on your riding style like I said. No one on here is going to fault you for any choice. JUST GET RID OF THAT STOCK FRONT TIRE!!! You will thank all of us later.
