German company updates its Clavicula cranks with power meter from Danish tech company Sensitivus Gauge

Looking for the ultimate extravagant upgrade for your bike in 2021? Well look no further than lightweight component expert THM Carbones which has released the world’s lightest crankset with an integrated power meter, tipping the scales at just 320g.

These new Clavicula SE crankarms are a progression from the already featherweight crankset produced by the German carbon experts and has been developed with Danish tech company Sensitivus Gauge. 

THM claims that the carbon moulded crank, spider and axle weigh just 320g, only 27g heavier than the non-power meter alternative. For comparison, that is over 200g lighter than the existing THM Clavicula crankset with SRM power meter which weighs 662g.

‘We are extremely pleased with the collaboration,’ commented Sensitivus CEO Rolf Ostergaard.

‘The integration of carbon fibres and strain gauges at this level required some next-level techniques to be developed. Together we have created something truly unique.’ 

THM believes the Clavicula SE power meter has an accuracy of +/-2% between 0 and 1,999W. The cranks are also available in standard lengths of 170mm, 172.5mm and 175mm with a maximum rider plus bike weight of 120kg.

The technology mentioned by Ostergaard used within the new crankset includes a cadence sensor and pedal metrics, alongside power reading, and is all kept going by a rechargeable lithium-ion battery built within the axle.

The power meter and cadence sensors will also be fully compatible with all major head units, GPS smartwatches and third party training apps thanks to ANT+ or Bluetooth.

Currently, the THM Clavicula SE carbon crankset with chainrings retails for £1,130 while the Clavicula M3 crankset with built-in SRM power meter costs a mere £2,915. In the middle, this latest crankset comes in at £1,783, which is practically a bargain in comparison.
