Hi Jim, thanks for reading!

That’s a good question. When you “free spin” the front wheel in your hands, or while the bike is in the work stand, it seems like there would be a lot of drag. I was nervous about that when I first tried a dynamo hub. There is a bit of difference between the three different hubs I’m currently using when you “free spin” them, with the SON spinning the longest, but only marginally. If you aren’t racing or counting minutes, the drag is nominal and completely unnoticeable when riding.

This article is very helpful, it helped me when I was diving into the dynamo world.

I hope that helped a bit.

~$500 is a large outlay for most cyclists, when a modern rechargeable lights for a fraction of the price can provide the same or better illumination (with batteries included). It’s also easy to carry small backup lights.

The Spurcycle bell is similar, in costing x10 a serviceable bell, or a SS King cage, BUT $50 is so much easier to stomach.

I like to go on Travel & Leisure magazine and tell ‘em they’re wasting money on some fancy-pants holiday in French Polynesia when a state park beach in New Jersey has sand and salt water too.

Hi Steve, thanks for reading. The bracket that the rear light is mounted with is an integrated part of that rear light. Hope that helps.

I’m with you on the utility of always running a dynamo hub and light. Too many times I’ve had batteries die or found myself caught out in the dark when a ride went long. Love the peace of mind of knowing I always have light (and power).
