Ask MBAction: Feeling Pressured
FEELING PRESSURED
Question:
I am just getting back into mountain biking again after a long break. My original mountain bike was a Trek 800 that I modified to ride in Big Bear, California. Now I have a Trek Marlin 6, and I added a RockShox air shock. With the added suspension on modern bikes, how does tire pressure come into play? With a 29-inch tire, 2.5-inch front and 2-inch rear, what should I run as tire pressure?
Thanks for any help.
