Re: [RBW] Re: Which Dyno Hub?

[Jacob Lopez]

I'm surprised I don't see more love for the Kasai hubs.  I have a Kasai hub 
and Kasai Trail Beam on my Clem and I love it, although I don't have a 
reference for other systems.  It's a relatively affordable combo.  It was 
my first-ever dyno hub/light setup and I absolutely love that for the first 
time I can actually see the road at night - not to mention not having to 
remember to charge lights. I always loved night riding, and now I love it 
even more.  Regardless of perfect optimization, welcome to the world of 
dyno hubs.  It's a magnificent place to be, and I'm sure you'll be stoked 
with any of these recommendations.

FWIW, Lael Wilcox, long-distance/rough terrain/all weather rider
extraordinaire, uses, or used to use a SP hub with her K-Lite. At least,
she used this setup when she broke the Continental Divide (or was it
cross-continental?) record.

I also use a SP with my K-Lite and I can't feel any drag or notchiness
compared to my SON 20R, but this may be due to the momentum or inertia of
the very tall and fat (29 1/2" X 2.4") -- albeit very light -- SP wheel
versus the short (25.6" X 1.6") -- also very light -- SON wheel.

Re: [RBW] Re: Which Dyno Hub?

[J J]

This is an enlightening and timely discussion about dynamos, as I'm 
shopping for one myself. Thank you.

Has anyone had experience with Velocity's dynamo hubs 
? I came across them 
haphazardly. I also wonder about Velocity's rear hubs 
.

Best wishes.

Re: [RBW] Re: Which Dyno Hub?

['Tom M' via RBW Owners Bunch]

This may or may not influence your decision, but The Pro's Closet has 
several SP dynamo Exposure Lights combinations for 
sale: 
https://www.theproscloset.com/pages/search-results-page?q=exposure%20lights%20revo%20dynamo.
 
I'm a fan of Exposure lights, so I went with this combination for several 
wheel sets I built up. I also have a SON wheel for my gravel bike. I felt 
some resistance with the SON initially, but it quickly went away. With the 
SP, I definitely feel drag or whatever through the handlebars, but can't 
say whether if affects my speed. I don't know if that's an anomaly with 
that particular dynamo because I don't have enough miles on the other SP 
wheels to say. As far as rims go, the gravel bike got Velocity Blunt SS in 
650b; the road bike got a Pacenti Brevit, also in 650b. I use an exposure 
rear light, which plugs into the front light; it will stay lit for some 
time after a stop, which is a nice benefit.

Enjoy wheel building.

Re: [RBW] Re: Which Dyno Hub?

[Toshi Takeuchi]

I agree with all that has been said so far.  I have a Shimano dynohub, an
SP dyno and an SON.  The Shimano is known to have slightly more drag than
the SON and the SP is pretty close to the SON. I have been commuting on my
Shimano for years (and previously on the SP for years on another bike) with
no problems, but it doesn't get cold in CA and it doesn't rain that much. I
would go with the SON for weather-related reasons (as mentioned earlier)
and style-related--it looks nicer, but I don't think sturdiness of wheel or
reliability is a major concern (unless you are really hard on your wheels),
as all of these hubs have been ridden for thousands of miles and I have not
heard of any spoke/hub breaks or other issues from any of the brands.

The only other reason for the SON that I can think of is if you are riding
at your limit or where a few extra minutes and slightly less effort means
getting more rest on a long ride (e.g. a brevet), then that would be worth
it for me (I have one on my rando bike--the extra bling doesn't hurt too
:-).

Re: [RBW] Re: Which Dyno Hub?

[Mathieu Brown]

Good morning Jason,

I was in a similar situation last year with my Platypus. I wanted to do a
dyno and I understood there to be only one quality option. When Will was
running through my build with me, he said something like "I mean, you can
but you don't need to? The SON28 is great but I have a Shimano and It works
95% of the way there for 50% of the price."

Now, since that conversation, Will's gotten a SON28 but, if you're looking
to see if there's a quality lower cost option? If you called him, I imagine
he'd make the same suggestion.

https://www.amazon.com/SHIMANO-Dynamo-DH-3N72-Generator-Hub/dp/B0029LD6D6

I still have my Shimano and it works great but I still think about the
SON28 that could have been...

Re: [RBW] Re: Which Dyno Hub?

[Brian Turner]

I've only had experience with the SON 28. My LBS tried to sell me on the
Kasai dyno when I was building up a gravel / adventure bike back in 2020.
and I almost went that route. However, I decided to splurge on the
reputation of the SON 28, and the fact that it seemed to be considered one
of the lowest drag options available. Apparently the advantage of the Kasai
is that it's field-servicable, should the occasion ever call for it.
