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.
Modern threaded bottom brackets aren't exactly a new invention. In fact, their roots date back more than two decades to Craig Edwards' old Sweet Wings cranks and Alex Pong's groundbreaking Magic Motorcycle. The idea is simple: by moving the bearings outboard of the shell, you can then use a much larger spindle.
