If you're looking for a dynohub for day-in-day-out riding then the Shutter Precision PV8 Dynamo Hub is certainly one to consider. It's under 400g in weight, puts out plenty of juice and has stood up well to the rigours of the British 'Summer', and at £90 is decent value too.
The Supernova Infinity 8 is a superbly engineered dynamo hub with some clever technology.
Dynamo hubs just get better and better, and with the increase in power and efficiency of LED light units there's never been a better time to switch over to hub power and ditch the batteries. The Infinity 8 is built to last and performed extremely well throughout testing. Whether you need its USP - the ability to switch it on and off - will depend on how much and how far you're likely to ride.
