The technology hidden inside the DUB spindle allows it to fit almost any bike without being obtrusive. Key features include: it measures left - side power via the DUB - PWR spindle - based unit to calculate total watts; it offers proven Quarq reliability and accuracy; it has a long battery life of 400+ hours, enough to power a whole season of rides; it's waterproof (IPX7, can stay under 1 meter of water for 30 minutes); a DUB bottom bracket (sold separately) adds durability and simplicity. Note that the right crank arm, bottom bracket spider, and chainrings are not included.

Using this SRAM Apex AXS Wide Left Crank Arm Power Meter Spindle Assembly is straightforward. First, make sure you have the appropriate DUB bottom bracket (which you need to buy separately). Install the spindle assembly onto your bike's bottom bracket area. Once it's installed, turn on the power meter and pair it with your cycling computer or other compatible devices. When you're riding, the power meter will start measuring your left - side power to calculate the total watts. As for battery life, it can last over 400 hours, so you don't have to worry about frequent battery changes during a season of rides. However, when the battery is running low, replace it with a new one as soon as possible. Since it's waterproof (IPX7), it can handle splashes and short - term submersion, but try to avoid long - term exposure to water. To keep it in good condition, clean it regularly with a soft, damp cloth after each ride. Check for any signs of wear and tear on the spindle and other parts. If you notice any issues, contact the manufacturer or a professional bike mechanic for assistance.
