SRAM equips XX1 cranks with watt measurement

More and more mountain bikers are riding with wattage measurement systems to better control their training. Sram is responding to this demand and is launching the XX1 crank with its own Quarq watt measurement system. With a system weight of 689 grams, the crank remains lightweight.

Whether in cross-country, marathon or enduro, athletes everywhere use the detailed evaluations of such watt measurement systems to make their training more efficient. The Quarq system and the XX1 cranks are both race-proven and so the "marriage" of these two parts is the logical step. The cranks are available in 170 and 175 millimeter lengths and with the X-Sync chainrings with 32 to 38 teeth. The XX1 pedals are also available with a Q-factor of 156 and 168 millimetres. However, the Quarq system is also compatible with the less expensive X01 and X1 cranks.

Before delivery, each Quarq power meter is individually calibrated at the factory. This allows Sram to eliminate possible deviations that can arise due to temperature differences. Thanks to the accelerometer, the Quarq power meter's cadence measurement works without an additional magnet. Sram also protects the system from water ingress. In extreme cases, it should survive one meter under water for 30 minutes without damage.
