Our in-house CNC machined "Strange" cranks and 47 T chainring are both lightweight (only 542 grams for the cranks and 118 grams for the chainring), strong (cranks made of 7076 T6 heat treated aluminum, chainring BCD 110mm - 47T - 2024 Aluminum) but are also made specific for our bike to work together, accepting a single chain ring with perfect alignment.
