SRAM dynamo hubs
I am looking for a 36h, silver, iso disc dynamo hub and SRAM's I-light D7 seems to fit the bill. As a bonus, it uses cartridge bearings, is well priced, and claims low drag.
Does anyone have experience with this hub? Is it recommended? Any issues to be aware of?

OK... I guess no one actually uses this. And it turns out that my LBS can't order it so it hardly matters. A phantom dynamo.

Beware. If you use one YOU may disappear.

Hi. The above link is a tremendous resource for dynamos, and headlights, and tail lights. He has extensively tested and filmed headlight beams. He also outlines a slew of dynamos, and talks about drag, outputs, wiring, etc.

I have the Sanyo hub on my Bianchi Volpe. It would probably end up at the bottom of the heap if someone reviewed all of the available hubs. I received it as a gift, so I had no choice in the model. I've found it to be entirely reliable. The drag is completely acceptable. In fact, I don't notice it. I run my lights day and night. At speeds of about 18 mph and higher, I feel a vibration through the handlebars, but I don't feel drag.
I have a very old "bottle" dynamo on my Raleigh Twenty. I can feel the drag, but it isn't annoying. Of course, I won't run it when I don't need it. I really should put a cap on the roller to "gear it down," because with 20-inch wheels, I'm spinning it faster than necessary.

Ah, duh, you're right!
Speaking of which, I found a mechanical odometer that runs on the sidewall. No calibration needed. I guess I'll install it on the Twenty. Most pressing reason for doing this: because I can.

I do have one. Ive only had it for about 45 days. As for drag, I can feel it but it can be compared to the drag of a chip & seal road. The BIG problem is......NO SERVICE PARTS!.....NONE! I have been trying to get a extra wire clip and my LBS said they do not service it. I thought WTF! So three e-mails and two service center calls later (NO e-mail replies) I gave up. I WOULD NOT BUY! Drop a few more bucks and get one with replacement parts available. Hope this helps, Bootsie.
