I have a Shimano hub, IQ Cyo front light, and seculite taillight on my Pelican.

No complaints at all. I keep all of the lights on day or night. Between 17 - 19MPH there's a distinct buzz from the hub, which seems very common ( with both the Shimano and Schmidt hubs ). Other than that, I'm perfectly happy. While there is a very minor level of improved performance in the Schmidt, it's not anywhere close enough to make me wish I had spent 3X the price. :-) I couldn't care less about the looks of either of them - how many people spend more time gazing at their hub instead of just riding the bike?
