I would just do the adjustment starting from the lack of trust in what was done in the factory. The cones affect sideway play and their impact changes as you turn the cones and locknuts.

I've been told by a certain blue-star member who seems to know a lot about Shutter Precision that Supernova Lights dynamos (dynamoes?) are in fact rebranded SPs. :innocent:

I've no experience with their dynamos but I have a Supernova E3 light and the quality and customer service are both top notch.

Its supposed to feel notchy - leave it alone ffs. It'll feel less notchy over time but never the same as a standard hub.

Calm down, I just don't want to ruin a brand new hub.

a new Shimano hub is not going to feel notchy from bearings, it's the magnets. I have thought about repacking my older Shimano dynohub, but adjusting it seems like it wouldn't be easy.

I dont want you to either, hence my over expressiveness:)

really would like to build up a shimano alfine 11 front hub and rear for my troll....all these posts are driving me crazy with desire for dynohubs and IGH...wow! Please break soon derailleurs and hubs ;)

This was very helpful. Thank you.

I highly recommend the SP (Shutter Precision) hubs. They are very light weight and low drag, yet cost the same or less than Shimano. I had a dynamo front wheel with SP hub and Velocity Dyad rims built by Longleaf Cycles last summer and it has been trouble free. It looks great and rolls very nicely. The cost was much, much lower than it would have been with a Schmidt hub.

unterhausen 07-21-16 01:44 PM

three year old thread. Not much has changed except I bought a Schmidt SL hub. I also have 2 of the SP 15mm through axle. this is the kind of purchase where you are still using the item long after you've forgotten how much it cost. Granted, the Schmidt cost more than twice what an SP would have, but the pain is already gone from that.

I was in a bike shop that offered a shimano hub on a pre-built wheel for $99. I hadn't ever really even thought about a dynamo hub, but for $99 I thought there was really no way for me to lose. I put it on my commuter bike (along with $120 headlight and $40 tail light.) That has been many years ago and it's still on my commuter bike - no issues. While I know that the schmidt hub has significantly less drag than my cheapo shimano, I haven't had any issues with reliability. A little over a year ago i converted to an e-bike, I don't care about the drag anymore.

zacster 07-24-16 11:56 AM

In the time since this thread was last posted to, I bought a Shimano dynamo hub. No complaints at all. I built the wheel myself, used a strain gauge, and haven't had to adjust the wheel ever. I put a Cyo Premium headlight on it and have been happy. If there is any drag, I'm not feeling it.l

Bought another Schmidt , after my Shimano-Brompton Hub Quit Putting out power

in 2 years, of only Local Use so Low Milage (But I'm only out $100, still got a Spare rim to re Use)

And Plug came loose several times.

B&M headlight Wire lead it's stripped then folded over in the plug, thats the contact.
perhaps splicing in thicker wire would tighten that up.

Shutter Precision PD-8 higher output at low speed. Dynamos are like climbing 4 feet every 1miles

I also have a SON SL since mid last year on my commuter/travel bike and having not to fiddle with the crimp connectors is a big plus for me. Not to mention the looks of not having a cable run up the fork. 4000km on the bike without a single issue.
I have an old SON on my winter/cx bike, also with no issues and about 7 yrs old with countless miles.. also no issues.
My wife and daughter sport each a SP dynamo, they also have no issue with those, but their mileage is maybe a 1/10 of what I ride, so not really a comparison of durability possible.

Another vote for SP. Full disclosure, I sell and install them, but I use one myself and am very pleased with it.
A few months ago, I built one into a wheel set for a guy that did a tour from Toronto to Costa Rica.
Here's a correspondence from him.
"Hi Dan,

I made it - 6066 kms in 35 days - epic ride and amazing training - now all I need to do is stay in bike shape for the next 6 weeks leading up to the race.

The wheels did great - no issues whatsoever - the dynamo was amazing. No flats for the first 2500 km then 8 or so the rest of the way. No problems with the bike either - all it needed was oil on the chain. "

SP Plug click into place ?
or just friction fit like Shimano? dependent on the wires for part of the friction..

It does click into place, but very little force required to pull it off.

Thanks for the link.

I've spent hours reading owner's reviews as regards dynamo hubs/lights .... I will be adding dynamo lights etc to my Surly LHT, aswell as my Bridgestone MB-2 mountain bike that I am converting with drop bars.

I've opted for the following:

Son 28 Polished (36 hole) part# 303601 dynamo hub

Lumitec IQ-X Black front light

Toplight Line Brake Plus rear light

Ewerk USB charger with cache battery and adapter cable

I have a Schmidt hub (3,actually), know other people that do, recommend it.
Generally, if you need lights on a randonneuring ride, it's prudent to have some backup plan also. The hubs are reliable, I have heard of a couple of lights getting water-damaged in heavy rain.
My preference for taillights is multiple Superflashes or similar lights, not just one.

Thanks for the comment. It was a fun series to do, and in the end, I got a free, perfectly functioning dynohub.

Custom stainless steel frame from Norwid. Model is called Aaland.
My commuter/shopper/travel bike with everything I ever wanted on a bike. :) A bit on the heavy side, so not as quickly to accelerate like my Trek Madone of course, but quiet and very sturdy with no maintenance required.

Here are a few pix to give you an idea: Bicycle family

And So, an improvement , albeit small , over a Shimano plug connection, which seems a pure friction fit,
Quite dependent on adequate wire gage from/to the headlight.
