On Peter White's website, he says the only notable difference is weight, and
that's only about 70g...

It would be nice to hear about a side by side comparison, but I doubt the
drag difference would be detectable.  I'm really enjoying my 3n71.

they are very comparable.  as i stated in my previous post, i find any
differences in weight and efficiency to be absolutely negligible.  my
only issue with the shimano is that if it craps out on me, i think i'm
pretty much out of luck (i could be wrong on this), whereas the
schmidt can be serviced.

for what it's worth, i find my shimano/B&M IQ CYO lighting set-up is
every bit as wonderful as my schmidt/edelux set-up. the big question
is, which set-up will last longer?

anyone have numbers on premature failures on the schmidt and shimano
dynohubs?

It's an older report (summer 2005) which doesn't include the newest
Shimano hub. Otherwise, very useful.

I'd be very interested to hear how the Shimano hubs are in comparison
to the Schmidt hubs.  I've been debating the dynohub vs. battery LED
set up for rando rides and the dynohub seems to be at least the more
environmental choice.   The only drawback with the SON hub is the
price tag, but at a 50,000km life between services, is it actually the
cheaper option in the long term?

Also, with the lights off, does the drag from the Shminano units make
a noticeable difference?

I just popped for one of these hubs - haven't built it up yet, though,
so I have no insight into how well if functions.  Feels lighter than I
expected (sub 500g, I think).

Any suggestions on lights?  At this point I'm thinking a Lumotec IQ
Cyo and a wired tailight also

[RBW] Re: shimano 3n80 dyno hub

2009-02-25 Thread Patrick in VT

i can't imagine the 3n80 is positively more efficient and lighter than
the 3n71 from the riders point of view.  i'm sure the numbers support
that, but for all intents and purposes, i bet they're very, very
similar.

i think differences in weight, and drag for that matter, are neglible
when considering the higher-end dyno hubs - they're all heavy, and
unless one needs absolute top "performance" for marathon brevet riding
or whatever kind of fast night riding one needs to do, i think the
3n71 is hard to beat, especially considering its price.

for the record, I also think the 3n71 is more than adequate for brevet
riding too.  the schmidt is "state of the art" and super high quality
(and the price tag reflects this), but i think i'd be just as happy on
my 3n71 on a brevet as I am with my schmidt.

for me, the only advantage of the schmidt (besides curb appeal) is
that Peter White can take care of anything that might go wrong with
the hub.

Hi Seth,

>From what I've read, it's significantly lighter, more efficient/less
drag, closes the gap on the SON28.
