Prices shown in currencies other than USA Dollars are estimates based on current exchange rates. We will charge your credit card in USA Dollars on the day your order is shipped, and the conversion to your local currency will be done at the prevailing rate by your credit card issuer.
Shipments outside the USA are declared as “bike parts” for customs purposes and will include the actual amount paid for merchandise and shipping. Jenson USA will not mark your parcel as a “gift”, declare a value lower than the actual price paid, or otherwise prepare false customs information.
Sram Quarq Riken BB30 Crank Arms are compatible with SRAM 10 and 11-speed road chainrings. Quarq strain gauges and electronics with +/- 1.5% accuracy are integrated in the spider, for minimum weight and maximum durability and protection from the elements. It's wireless ANT+ enabled, and interfaces with all industry standard receiving and display units. All calibration values are stored in the spider itself, meaning there's no need to recalibrate if you change heads or chainring sizes. It uses the coin-style CR2032 battery, which will last over 300 hours. Note: This purchase does not include the bottom bracket, head unit or training software.
