      THM Carbones Clavicula crank SE Road 2-53 | 39 standard

      The clavicle SE is a full-carbon crankset with integrated Carbon axle. In the development, special emphasis was placed on optimal structural design. Special mention should be the Spider for sprocket carrier. It has been defined both geometrically and structurally only by analysis of load paths. Here an extreme lateral rigidity for optimal switching performance and excellent rigidity in the circumferential direction for lossless power transmission originated. This optimization was, so to speak, as a side effect, an exceptionally stiff and lightweight crank overall system.
      Is especially proud of THM-Carbones on a patent for the compound of the left crank to the axle. For the first time here is a combination of materials Carbon-carbon is used, which have been tested very extensively and successfully in recent years. What matters is that here the relative movements could be minimized between the teeth through identical fiber construction of external and internal gearing. The result is that there is virtually no wear and no possibility of noise at this point. With the clavicle SE permitted by THM-Carbones standards are significantly shifted. It can be considered as a new reference at the Kurbelbau.
      The cold forged chainrings of Practice Works allow precise shifts over a long period. The advantage over milled counterparts, the possibility is optimal to form the tooth profile and more durable through the forging process.
      The LevaTime chainrings are the culmination of years of testing and fine-tuning. The end result are now a number of the best and switching fastest chainrings available.
      At LevaTime chainrings several shift pins are optimally positioned at locations to offer a perfectly timed switching operation. Synchronized switching ramps on outer chainrings are matched with a suitable inner chainring and allow the chain clean to turn upwards.
