THM Clavicula M3 Crank Arms

Precision engineered from carbon fibre, the Clavicular M3 Crank Arms by THM are designed purely for riders who want premium performance paired with high-end materials that are guaranteed to shave weight off your road bike.

The crank arms are highly versatile, with the ability to interchange the spider for use with a variety of chainring configurations. Whether standard 130 bolt diameter or 110 compact variants, everything is achievable with the Clavicula M3.

With a 148mm Q-factor and linked with your choice of chainring, these crank arms are made to fit any frame with a 68mm or 73mm BSA shell. With its impressively low weight starting at only 325 grams and its high level of stiffness optimising power transfer, these crank arms are sure to provide top-level performance on the tarmac.
