German carbon manufacturer THM Carbons is no stranger to attractive lightweight components, and its Clavicula SE cranks are always on the wish list.

The cranks, spider, and 30mm axle are made of carbon, with a choice of 110mm or 130mm BCD; according to THM, the former weighs 320g with strain gauge and the latter 329g. This is THM's first all-in-one power meter, but the German brand has also produces carbon crank arms for SRM's Origin modular power meters. For reference, SRM's Origin power meter and THM arm weigh 570g, Quarq's D-Zero weighs 560g without chainrings, and the Stages Carbon GXP left crank arm alone weighs 165g.

All electronics, including strain gages and rechargeable lithium-ion batteries, are housed inside the axle. Battery life is estimated at 150 hours; according to THM, the Sensitivus power meter also measures cadence and advanced pedaling metrics such as torque effectiveness and pedal smoothness, but measurements are taken from the left side only, similar to the Stages and 4iiiii. [The adoption by a company known for uncompromising engineering is proof that our power meter technology fits everything from sublime high-end cranksets to very high volume. Rolf Ostergaard, CEO of Sensitivus, said, "This adoption reaffirms our pride in this power meter technology and our confidence in driving future innovation in this field.

"We are very pleased with this collaboration.

"To integrate carbon fiber and strain gauges at this level required the development of next-generation technology. Together, we have created something truly unique."

It is surprising that Sensitivus has partnered with a brand like THM, a company that makes such high-end "halo" cycling components for a living: in February 2020, this Danish company published a blog post explaining how it manufactures power meters for about $10. While not an apples-to-apples comparison, there is a price difference of €780 between a power crank and a non-power crank.

The Clavicula SE crankset speaks both Bluetooth and ANT+ languages, so it should be universally compatible with head units, smart watches, indoor cycling apps, and the Team Zwatt app for calibration, firmware updates, etc. It should be universally compatible.

THM states that the Clavicular SE power meter has a reading range of 0-1999 watts with an accuracy of +/- 2%. Crank lengths of 170 mm, 172.5 mm, and 175 mm are available, and the maximum allowable weight, defined as "rider + bike + luggage," is 120 kg/264 lbs.

If the TMS Clavicula SE is of interest to you, it costs €1,975.00 (about $2,429 / 1,783 lbs / $3,128 AUD), so you better have some room in your pocket.
