The Long Life chain ring we developed at idworx made of hardened stainless steel with an uneven number of teeth together with the extra-hardened idworx KMC E1 ePT chain and the idworx Rohloff steel sprocket, makes for unprecedented longevity. In our oPinion models we even fit our Long Life chain ring back and front. Chain tension requires less frequent checks - a pleasing consequence of a more wear-resistant drive.
