Tune has the Triebtreter SL to a combination of single chainring and Spider in the program, which can be mounted on the house cranks Smartfoot and Blackfoot. Furthermore fits the Spiderless chainring on BOR cranks XM557 and XC666. The Combi is bolted directly to the crank arm. This saves weight, is very stiff and ensures a clean as individual appearance. A 7075 Txxx aluminum alloy ensures a low wear. The chainrings have special teeth (narrow wide) which prevent the chain may come off. The principle follows that of SRAM XX1 chainrings. In conjunction with a Sram or Shimano Shadow Type2 + derailleur, which have greatly increased bias of the cage, the chain is reliably held in place without chain guide.
