Note: this data is for the original version with evenly spaced slots. There is a newer variant ("semi-radial") as of 2016 that pairs the spoke slots at the hub slightly to create a slight amount of wrap angle in the spokes. This should very effectively resist rotational vibration harmonics in the wheel as it is being ridden due to the pulsing resistance of the hub under electrical load. -Karl
Dynamo for Brompton that uses STRAIGHT PULL SPOKES!! 28-slot "drilling", radial lacing only. (spoke length is measured from the underside of the head) spoke hole diameter is zero because it would offset the length calculation. Weight of 380g is with the stainless steel bolt-on skewer provided. -Karl
