1. Dim the tablet display. First up, and perhaps the simplest way to save battery life, is to dim the tablet display, much like you would on a desktop or laptop PC. Simply visit the battery usage page, opt out of the auto-brightness controls, and manually dim the brightness as you see fit.
Where is the Bottom Bracket on a bicycle? In a nutshell. Your bottom bracket is housed in the bottom bracket shell of your bike frame, it connects your chainset to the frame and allows the cranks to turn smoothly. When selecting a replacement bike bottom bracket you need to make sure that you get the correct model.
A lock nut to secure the stem at the wheel rim and a valve cap may also be present. The outer valve stem is manufactured in various lengths for different applications, and has a narrower diameter (6 mm) than Dunlop and Schrader valves (8 mm). The weakest point of a bicycle rim is usually the hole for the valve stem. The smaller hole for a Presta valve makes it possible to have extremely narrow wheels while maintaining sufficient strength in the wheel. The air pressure in an inflated tire holds the inner valve body shut.
