To tell you the truth, I look down at my tire before I jump on, most people can tell if they have a slack tire, if it looks good, I ride. I have got down a checked my tires several times when I first got my bike and you know what I found, it didn't change from the first time, other than the air I lost when I was trying to get the darn gauge on the stem! It's your money, buy the FOBO's and have that piece of mind if you want; me set it and forget it unless there's a BIG temp change! Ride more, worry less! PS. I know I am about to get flamed but, a question for anyone that wants to be real, anyone one that runs the FOBO's, how many times do you have to make a change in pressure in a season? Truthfully
