I'm thinking I'd like a warning when a nail or screw, e.t.c. punctured my tire as its been invaluable on other bikes for me. Any recommendations on a TPMS that you guys are using and feel will promptly notify or display pressure changes allowing rider to pull over, plug, and inflate tire. I have concerns that the valve stem screw on devices that attach without breaking bread on tire may not be as accurate. But I hope some of you would have a different opinion or experience as this option may be cheaper. Regards.
