SRAM Rival DUB AXS Quarq Powermeter Crank Road 2-fold
A crankset with an integrated power meter has never been so cheap! But the new Rival AXS power meter platform not only impresses with its price, it also offers your bike a particularly clean look. This is made possible by the complete integration of the measurement technology into the DUB crankshaft. The performance of the left leg is measured, from which the overall performance is calculated using an algorithm. Thanks to the many years of experience of the Quarq power meter specialists, the measurement is carried out with a very high level of reliability and accuracy. The battery life of up to 400 hours should cover the operation over one season for many bikers. Should you ever run out of power, the lithium AAA battery can easily be replaced by yourself. For use in adverse weather conditions, the power meter unit is waterproof according to the IPX7 standard. In contrast to other power meters, the additional weight of the power meter unit remains pleasantly low at 40 grams.
The Rival DUB 2-way crank offers a higher bandwidth and at the same time smaller gear steps. What sounds absurd at first is made possible by the new X-Range gear ratios in combination with the Rival 12-speed cassettes. Thanks to the cassette's 10-tooth sprocket, smaller chainrings are sufficient to achieve the same maximum development as with an 11-tooth sprocket. Due to the smaller size in connection with the unique one-piece design, the chainrings have become lighter and stiffer at the same time. The small difference of only 13 teeth between the chainrings ensures precise and reliable shifting behavior and leads to fewer compensating shifts on the rear derailleur. The Rival is visually convincing with its polished, black aluminum crank arms, which are available in lengths from 160 to 175 millimeters. The crankshaft for the new DUB Road bottom bracket standard was developed for a wide intended use With the corresponding DUB bottom bracket, the crankshaft is compatible with all common bottom bracket housings.
