InfoCrank M30 and InfoCrank Classic is more readily available as a 110BCD, often known as a Compact set. Our chainring supplier, the respected US company Praxis Works, is not currently producing 53/39 chainrings in 110BCD, but in 130BCD only. 


Specialites/ TA however, do make a 53/39T pair to fit 110BCD, and we offer these for sale through our online shop.  Our crankset is designed for precise chainring shifts as well as accurate power metering.
