The P in the model name stands for POWER. The P7 series from Shutter Precision is powerful and efficient at a very low weight.
Shutter Precision has updated, redefined and refined the concept of hub dynamos. The result is an ingenious precision instrument with an attractive appearance: the PD-7 for 12 mm thru axle and with 6-bolt brake disc mount. And with just 419 grams the PD-7 is a lightweight among the hub dynamos.
In addition, the P7 Series is one of the most efficient on the market, delivering 72% of its maximum power at 15 km/h with a much lower weight than other manufacturer's 3 W dynamos. The PD-7 hub dynamo is the model of your choice, StVZO compliant and optimal in all wheel sizes up to 28/29 inches, because it produces even under 5 km/h the 3 W power at 6 V voltage which are required by the German StVZO.
