Cranksets

The "Clavicula Compact" is the compact version of our super light race crankset, enabling you to use smaller chainrings. Technically identical with the standard “Clavicula”, it maintains the same record-breaking stiffness-to-weight ratio. Typical chainring combinations used with compact cranks are 34/48 or 36/50. While giving similar gear ratios to triple cranks, the smaller chainrings found on compact cranks yield a better chainline, better shifting and fewer doubled gears. In addition, the shorter spindle allows a greater lean angle in right hand turns. And last but certainly not least, many riders simply enjoy the compact crank’s better looks compared to triple cranks. As with our “Clavicula” the cranks are delivered without chainrings. The bolt circle diameter is a standard 110mm. A bottom bracket and mounting tools are supplied with the cranks.

The “Clavicula” is a revolutionary new design of an all-carbon crank. They are designed in close cooperation with the Cologne-based design-specialist formagic. New production methods, never before used for cranks, achieve a giant leap in total stiffness. The crank’s stiffness-to-weight ratio is setting new standards. In-house lab testing of various high-end cranks shows the superior performance of our crank system. The cranks are designed for road bike applications with a 130 mm or 110 mm bolt circle diameter and for 68 mm bottom bracket width. 170mm, 172.5 mm and 175 mm crank arms available. The sealed bearing bottom bracket attaches outside of the frame using the standard BSA threads. This design allows the use of larger diameter bearings and a wider bearing placement. In combination with the 30 mm diameter axle these modifications make for a very stiff drivetrain. Optional BB shells for Italian threaded frames now available upon request. Furthermore an adaption for the BB30 and the specialized system are available. Extensive testing of this ground-breaking invention was our top priority. We are currently undertaking various long term and stress tests, because as a pure-bred racing component the “Clavicula” must be able to continually withstand highest loads – be it in hard sprints or during the toughest classics. Both static and dynamic tests have been completed successfully. However, to aviod even the slightest risk we are currently setting a rider weight limit of 95 kg (207 lbs.). Your safety is our main priority!

Uphill every gram counts. Thus, this is what we paid attention to when developing our super-light and stiff “Clavicula MTB” for mountain bikers. The result of a long period of development and uncountable test runs, we present what may be the world’s best MTB racing crank. At only 440 g including BB bearings and spindle the “Clavicula MTB” is lighter than any competitor and therefore impossible to beat on demanding terrain where you have to fight you way to victory over countless grinders. Aside from the seconds the lower mass shaves off your lap times, it also improves handling of the entire bike. Technical sections become easier to master – the “Clavicula MTB” puts you ahead of the pack As the regular “Clavicula” the new crank is shipped without chainrings, allowing you to choose any set with the common 104/64 mm BCD. The granny with its 64 mm BCD must be 22 teeth or larger. The crank comes complete with bottom bracket and mounting tool.

The “Clavicula DH” is the downhill version of our superlight racing crankset. Designed with additional reinforcements it is intended for the extreme demands of downhill racing: Even flying debris, crashes on rocky terrain or sliding along the ground can hardly hurt this crank. Thanks to intelligent design it is still light as a feather. The low weight of the “Clavicula DH” improves the overall handling of any DH bike. A lighter bike will always be more responsive to steering input and thus easier to control. At only 450 g for the complete crankset including the bottom bracket the “Clavicula DH” is much lighter than similar sets. Power transfer and longetivity satisfy the most demanding racer. The crank comes complete with a 38-tooth chainring and is shipped with bottom bracket and mounting tool.
