Any reviews from users of the Shutter Precision Hub Dynamo?
 

We are having a new Cargo Bike built this summer and the builder offered a choice of equipping it with a Shimano or a Shutter Precision Dynamo front hub. Does anyone have experience with the Shutter Precision? It sounds great, and a great price. We would have it built on a 20 inch front wheel.

Weight is rather light...

Thanks all,

We run two SP Hubs, a pd-8 on our tandem and a pv-8 on a bob yak trailer. The yak has only seen limited use but the tandem wheel is at [MENTION=205580]250[/MENTION]0 trouble free miles. I do not have any previous dynamo experience to gauge against but I would certainly recommend these. We have the light constant on and have not noticed the additional drag etc.

Does the Shutter Precision make much noise?

I'd go with the Shimano simply because of its user serviceable bearings. Why not Velogical? I thought you were sold on those?

No, we do not get any noise or vibration out of the hub when riding

I have the velogical on my distance bike and love it for occasional use. This thing is going on a new cargo bike (Smallhaul) that we plan to basically leave running all of the time though. Yes, I am still a big fan of the Velogical, but I also am a fan of the right tool for the right job. I think a conventional dyno hub is a better fit for continuous use... (Plus I can't resist trying something new too!)

I run a Shimano DH3N80 and a DH3N72 on my commuter bikes, and I have a spare wheel with a Shutter Precision hub dynamo for any other bike that may need lights. All three are excellent, and the Shimanos have been so for years.

Main differences are: the SP is lighter. And I used to think the SP would not cause vibrations at higher speeds, unlike the Shimanos. However, turns out it does vibrate if you happen to connect a rear light too -- yet, to confuse matters, not with every rear light, just with the ones that draw a lot of juice.

Very interesting and good to know. Nice to have input from someone who owns both. Is the Shutter Precision quieter than
the Shimano when it is running just a headlight?

I have Shimano XT T785, LX T670, and SP PD-8. Shimano is heavier, and draws more power with fewer rotation (light starts up faster). SP PD-8 is a sexier hub, as far as user serviceability goes, if mine ever craps out, I will attempt to service it myself.

A guy I ride with has had two SP hubs stop generating. He's using a luxos with USB output and does a lot of miles.

Why would any of them make any noise? They're all dead silent.

I have both, they don't have any noticeable differences. The only reason I have an SP is the 15mm thru axle. Otherwise I would have stuck with a Shimano. But if you can deal with the drag, noise and vibration of a wheel dyno you'll never detect a hub dyno.
