THM Clavicula XC 山地車碳纖維曲柄

Outstanding aesthetics at record-breakingweight. With the XC version, THM is launching a suitable version of theirlegendary Clavicula crank arms for fast cross-country race bikes. In contrastto the previous Clavicula M3 version, a carbon shaft now connects the crankarms, as with the Road version. The relative movements between the teeth couldbe minimized by an identical fiber structure of the external toothing of theshaft and the internal toothing of the crank arm. As a result, there ispractically no wear and no possibility of noise development at this point. Thecarbon spider with 52 millimeter BOOST offset for chainrings with 104millimeter bolt circle diameter is also laminated to the crank arm. Despite theintegrated spider, which allows for lighter chainrings, the weight of theClavicula XC has dropped by 35 grams compared to the M3. For broad framecompatibility, THM offers bottom brackets for BSA, BB30, PF30, PF92 and PF89.5shells.
