Using this SRAM Apex AXS Wide Left Crank Arm Power Meter Spindle Assembly is straightforward. First, make sure to buy the DUB bottom bracket separately and install it on your bike. Then, attach the crank arm and power meter spindle assembly. The power meter will start measuring your left - side power, and you can calculate total watts. For the battery, since it has a long life of over 400 hours, you don't need to worry about frequent replacements. However, if you notice a significant drop in performance, it might be time to change the battery. When it comes to maintenance, as it's waterproof, you can clean it with water. But don't submerge it for longer than 30 minutes or deeper than 1 meter. Remember, the right crank arm, bottom bracket spider, and chainrings are not part of this package, so you'll need to get them separately if you need them.
