I’ve been running an sv-9 for a few years and it’s been great. However, it
doesn’t fully power the IQ-X on long/steep climbs, so you wind up with a little
flickering. That can be a little annoying, especially when riding with others,
but sometimes that just encourages me to ride faster :)

Since I knew I would be running an LED light with no chargers (a B IQ-X), I
went with the SV-8. Though designed for smaller wheels, the lower power draw
of LED lights allows for this... That said, I haven't used a dynamo designed
for 700c wheels with my light, so maybe there is a performance
