I've always preferred Shutter Precision for my hubs. I rode Colorado Trail and Baja Divide with B&M IQ-X and honestly it was a great light. Perfect on road, good enough on the trail. I have since upgraded to a Sinewave, which is crazy bright. In theory, it can be run off of an external battery, like a flashlight, eliminating the low-light-while-climbing issue. I haven't used this feature yet because it doesn't bother me much but it can be annoying to stop and not have any light. I am also put off by the flickering during technical descents that is caused (I think) by the front wheel stopping momentarily. This is during jumps or really loose gravel where the front wheel may lock up a teeny bit. Otherwise, plenty of light. It is great.
All said, I would love to compare the KLight and Sinewave. Having ridden both, they are both excellent lights. The Sinewave has more features (built in charging, etc). I don't know how much of a difference a hub would make. I have also used Shimano dynamo hubs and they're heavier, clunkier, louder. I don't honestly *feel* a difference in loss of power when riding though. just my 2 cents On Monday, April 29, 2019 at 3:33:45 PM UTC-7, Collin A wrote: > > Given some discussion in another thread about dynamo lighting use on > unpaved surfaces, I figured it would be worth bringing this up as a > separate thread. > > Personally, I have a kasai Dynacoil hub (evolution of a SP hub, I believe) > laced to an Alex Dm24 rim and wired with a K-lite bikepacker light (gravel > version) https://www.kliteusa.net/product-page/klite.
