Using your Shutter Precision Dynamo Hub PD-8X is straightforward. First, make sure to properly install the hub on your 26”/700C bike with a 6-bolt disc brake system. The 15mm thru-axle and QR adapter make the installation and removal process easy. When using the bike, the hub will generate a 6V3W output. This can power your bike lights or other small devices.
