I have the opportunity to swap from a 160 disk to a 185 disk for no extra charge.
The bike is a 2008 Marin Rift Zone
The brakes are Avid Juicy 5
The fork is a Fox 32 RLC
The shock is a Fox R
is it worth changing to the bigger disk or not, would I feel a marked difference. Riding is XC with some fairly fast downhill sections going on for a couple of miles
