A practically flawless performer. Used to power a front B&M IQ Cyo R and a rear B&M Toplight on my commuter bike.

Pros: Light

Cons: Some unsettling vibration at speeds exceeding 50km/h, no 24/28 spoke drillings available.

Fantastic Dyno Hub at a very Fair Price

I used the 3N80 version of this hub to build a wheel for one of my recumbent bikes. It's a 20 inch (451) rim, and his hub is designed around a 26/700c wheel. At first I had concerns that this would cause extra drag, due to the higher rotational speed of the smaller wheel, but that isn't the case (at least not at any level I can detect)

When I first got the hub, I was very concerned about the "notchyness", but once I built the wheel up and gave it a spin my fears started to diminish. On the test stand an easy spin of the wheel resulted in a good solid 10+ second of rotation.

When I first rode the wheel there may have been a tiny amount of buzzing / vibration at low speed, but that may have been my imagination. I can't tell the difference between this hub and my old one (which was very smooth and freerunning) on the road. I set a personal best for a 60 mile ride with it on the bike, so I'm sold on it.

I've got it paired with a IQ CYO light, and the first time I switched the light on, all I can say is WOW! Bright and sharp, still no drag that I could feel while riding (Do notice it on the test stand, but not in the real world).

All in all, this hub is a great value for anybody looking for a top quality, low drag dyno hub. It's a much more affordable pricepoint than the "German Made One", and from what I've found on the web where people have actually tested drag in a controlled environment, 99%+ as effective in terms of drag.

All of the various models use the same internal mechanism, about the only difference is the cosmetics and disk brake compatibility. The 3N80 is the one with the 'cut-aways' on the right side of the hub, and I have to say it's a very sharp looking hub.

Pros: Very low drag, both on and off
99% of the performance of the SON, at 50% the price
Variety of styles to fit your need.

SHIMANO DH3N80. i did a lot of research before i bought this gen. universal price w/ custom wheel build made it an easy choice. absolutely super...yes a little weight, but the convenience and power make it an overwhelming choice for the commuter,long distance rider...mine is on day and night. it comes off-road with me and i beat it up!
i actually tested sram and other shimano's. dh-3n80 was a clear winner...very, very smooth. ultegra quality finish and internals.
hooked to a B&M Lumotek IQ front and a top light rear.
very cool invention. part of a universal custom wheel build.


Pros: weight, very smooth, takes a beating, ultegra quality, nothing, except a schmidt ($100+ more) compares, long distance security, always there

Cons: doesn't come in 24/28 spokes

Nexus hub

Built my very first wheel with this hub. It turned out great and it was a great addition to my commuter bike.

Pros: Primo quality if a little heavy and possibly more drag than the SUN

Cons: Seems like everything accomodates disc brakes now. I have yet to own a bike with disc brakes. This add-on was unnecessary for me though I understand why it's done.

This is for the DH-3N80. I had Universal lace this to a Velocity Dyad (700c, 32h) with Wheelsmith DB spokes. It's powering a Lumotec IQ Cyo on my commuter. I noticed the magnets "pulsing" when I turned the axle with my fingers, but honestly couldn't detect any additional resistance when I was actually riding. I've never ridden/tried a Schmidt dynohub, so I don't know if the Shimano offers more/less resistance. I do know, however, that the price of the Shimano unit made the decision a no-brainer.

Pros: Price
Easy to install (wiring)
Looks

Cons: Requires a new wheel/(re-)build

Never Worry About Batteries

I commute daily, year-round. My bike came with an inexpensive B+M headlight / tailight with a bottle generator. The headlight never put out enough light and I could really feel the drag of the bottle generator. The loud whine was very noticeable as well.

I bought a nice Night Rider LED headlght, which worked well, but I didn't like having to charge the batteries every few days.

I upgraded to a B+M Lumotec IQ Cyo headlamp, powered by this Shimano hub. It works easily as well as the Night Rider light, but I never need to worry about batteries. The hub is quiet, and I don't notice any drag at all. It seems like magic.

Pros: Works just like you would hope

Cons: None.

Great value and Performance

I have the DH-3N80

Well, a great value compared to SON hubs ($300+) anyway. I compared and the additional drag that this Shimano is supposed to have over the SON is certainly acceptable considering the price difference.
I built this up 32 hole for my commuter and use a single Supernova E3 Pro . . . an incredible light. I've run it one winter season with no problems. I live in las vegas, so now real worries about wet conditions.

Pros: Relative value,
Nice finish


Cons: Would prefer sealed bearings

Shimano Nexus dyno hub

Great thing to have. Combined with an IQ CYO light I had great lighting all last winter and this far with no hassle with batteries. It just works.

Can't really feel the resistance when it is running.

Pros: Just works, no worries.

Cons: Not cheap but cheaper than the Schmidt.

This being the only generator hub I've used, I can't compare it to anything else. However, I do own two now that's how much I like it. With the price jump being so large to a "better product" I really thing these hubs are full of value.

Despite my slow speed uphill on my former commute in San Francisco (sometimes 4 mph) I was still able to generate enough light to feel safe with my 700c wheels. I don't really notice the vibration or drag others do, but I also have cushier tires.

I would recommend this hub to anyone looking to try out a dynamo lighting setup without breaking the bank.

Pros: -Very reasonably priced
-Disk option
-Easy to install

Cons: -contacts are on the "wrong side" for US roads.

WOW- I can really see the road at night. I purchased this hub as part of a custom wheelset ( shimano Nexus Dynamo hub, DT Swiss TK540 Rims & Shimano Rotor ). I truely don't feel any extra effort required to drive my IQ Cyclo head & tail lights. I can reach down while spinning and turn off the head light - nochange in effort. I this is going to save me a fair amount of weight over the standard batteries for my nightrider light. Very clean and one of the few Dynamo's that work with disk breaks. Universal did a fantastic job putting this togeather with the TK540 Rim.

Pros: Lots of light, for very little effort.
great price

Cons: too bad it doesn't come in black.
Universal didn't have a good selection of lights to go with this -- had to purchase from different source.

This is a great hub. I'm using it to power a Supernova E3 Triple and it's great to no longer worry about the state of my batteries. With the light off, the wheel spins freely and smoothly.

I've not had a change to use it with disc brakes yet, but it may be in the future, the expandability is a nice option.

The quick release wire connector works well once I figured it out, I don't recall seeing any instructions. The connector is two pieces, take them both off and separate them. Strip about .5 inches of the wire and run them into the gray inner piece of the connector. Then wrap the stripped wire around the top of the gray piece into the two channels. Lock the wire in place by sliding the gray inner piece of the connector into the black outer piece. Now when you need to remove the wheel, just pull off the black outer connector and the wires stay dressed inside, ready for reattachment.

Pros: Versatile, reliable

Cons: Weak instructions
