The SRAM Quarq Rival E1 crankset features aluminum crank arms and a spindle-based power meter, designed for riders who want to track their training data. The power meter measures power from the left leg and calculates total power in watts from that. The user-replaceable AAA battery lasts over 400 hours, enough for a season of riding. It weighs less than 40 g more than a standard crankset.
The DUB bottom bracket adds durability and simplicity. The chainrings are integrated into a single piece, with a choice of 46/33 or 48/35 teeth: choose based on the terrain you ride most often. Front shifts are precise thanks to X-Range technology, which provides smoother progression. The crankset is water-resistant to IPX7, up to 1 meter for 30 minutes.
