The crank is one of the most complex components in terms of aerodynamics. The leading edge of its shape becomes the trailing edge 180 degrees later, and there are significant factors at play, including the major influence of forward speed and the minor influence of rotational speed. Additionally, your feet are spinning by, the frame is right there, the chain runs over the chainring and can’t be easily optimized aerodynamically, and so on.
Our best aerodynamic shape resembled a knife, measuring just 12mm wide at the pedal—significantly thinner than anything else available (most cranks are 15-17mm wide at the pedal end). In the other direction, our desired profile was much deeper than usual.
The transition to the spider is another challenging area. For structural and stiffness reasons, we wanted the spider to be integrated with the crank arm, with fibers running through both. At the same time, we needed the chainring to be spatially separated from the drive-side crank arm (rather than forming a blended shape) to avoid aerodynamic blockage. The Torno spider achieves exactly that and works in unison with the dedicated Torno aero rings.
Back in 2016, we decided to bring the production of our high-end carbon parts back to Italy, starting with the Torno crank. Today, we have the most advanced factory for manufacturing complex bike components at our headquarters in Presezzo, Italy. Combining automation with skilled manual labor, this is where we produce the Torno from the ground up. Raw carbon fiber and resins are brought in, and after undergoing a series of proprietary processes and meticulous craftsmanship, the world’s most beautiful cranks (if we may say so ourselves) are shipped out to you.
Thanks to this in-house manufacturing, the Torno and Torno Wide are among the world’s lightest aero cranks, despite also being the thinnest and having the lowest Q-Factor on the non-Wide version. This level of precision simply wouldn’t be possible anywhere else.
Narrow is aero and the ultra-thin crank arm blades cut through the air more efficiently. Torno has a 142mm Q factor, keeping your feet closer together which provides additional aero efficiency and , on average, the better biomechanical efficiency. Torno Wide features a 150mm Q Factor for the whom who prefer a wider Q Factor compared to the original Torno or needs to use a Sram Full Mount transmission.
The Torno is optimized specifically for 1x drivetrains. That allows us to use straight crank arms (no need to clear the front derailleur), which makes them more aero and lighter. It also allows for better spider integration. Perfect for improving the perfonamnces of your !X road or gravel bike.
Of course we can't reveal the exact layup, but we can say it’s not just a blend of different moduli but also unidirectional and woven materials. Unlike what you often see, this woven is not cosmetic but an integral part of the structure to achieve the Torno's incredible weight & stiffness.
Unique carbon axle directly integrated in the drive-side crank arm and spider. This is the stiffest and lightest design possible (and unfortunately, also the most complex and most expensive). But when only the best is good enough, this is the best.
The spider is separated spatially from the drive-side crank for aerodynamic reasons. Structurally however it is integrated with the axle and crank arm as well as the chainring, not only through its four bolts but also via its (patent-pending) countersunk design.
These 1x-specific chainrings are made for the best performance. The countersunk bolt pattern is dedicated to the Torno & Torno Wide spider, transferring your power not just via its bolts but also its shape for optimalpower transfer.
