Something which is nicely illustrated by the graph below.
The lower the pressure, the higher the comfort. A lower-pressure tyre is more capable of absorbing bumps and vibrations. An example: The 28 mm tyre offers considerably more comfort, since the overall pressure is lower. Enough theory at this point…. In reality, a 32 mm tyre feels like it has more rolling resistance than pressur 25 mm one, sigma sport bike computer tyre pressure the difference in width is significant.

The company says this system is ideal for those who are riding in remote locations or on multi-day trips where self-sufficiency is important. Because the system is constantly charging, in theory you can add and release air pressure as many times as you like during the ride.
The benefits of being able to change air wahoo cadence sensor strava up or down during a ride are pretty obvious. Ramp up the pressure for hard surfaces or climbs, dial it down when the trail gets gnarly or loose.
It took me a few rides to remember to hit the start button on the monitor before I began my ride. Aside from that the screen is large ttre a clear display.
It compute has a functional backlit screen, sigma sport bike computer tyre pressure temperature, gradient and calorie consumption estimator.

I'm so used to replacing batteries in all my other GPSs that I thought the battery in this was pfessure replaceable - Its not. You have to plug the device into a mini-HDMI power chord, which fortunately aligns with my sigma sport bike computer tyre pressure and other gadgets.
Not sure that is a pro or con. The device also takes several hours to recharge but I guess that's normal. I'm still happy with the monitor now that Sigma sport bike computer tyre pressure think I finally have all the quarks worked out with a viable solution.
I'm keeping my review at 4 stars. When the battery goes you must find a charger. Also, rechargeable batteries lose their staying power over time. When this battery degrades you must replace the entire unit.
I've become use to this now so no big deal, but for the few few weeks it was hard to remember. In sigma sport bike computer tyre pressure end its a nice big Tyrd screen with lots of features. Screen goes blank after a few rides, reads "Low Battery" it will not charge.
