This Upgrade converts a standard SRAM Rival AXS crankset into a power meter. The resulting crankset combines the benefits of the Rival Crankset with the long-standing power meter expertise of sister company Quarq. Lots of technology in a small package The electronics which measure the power are cleverly hidden in the DUB axle. This ensures that this power meter is very resistant to bad weather conditions while the weight of this addition is minimal. The use of this DUB-axle ensures that this power meter fits in almost every frame. Battery life The SRAM Rival eTAP power meter has no internal battery but uses a replaceable lithium AAA battery. The downside of this is that you’ll need to replace it from time to time. Luckily the battery lasts for more than 400 hours which is a lot longer than most internal batteries in power meters. DUB bottom bracket The DUB technology ensures that the bottom bracket and crank arm are not only rigid and transmit power instantly but also that the crank lasts a long time. By simply integrating the crank bottom bracket and sprockets you can expect better power transfer and less maintenance in return. Installation is also very easy!
