Shimano Nexus 8-speed Hubs

It's been over a year since we first placed our order, but we finally
have received Shimano Nexus 8-speed hubs.

I bought one myself, I'll be doing it up with 650B rims...

I've also scanned and put up the Service Manual for these hubs at:

Thanks Sheldon for the info.

Do you know how many planetary stages the hub has,
and what combinations of stages are used in each gear?

Shimano says it has a silent clutch; is there no pawl
click when coasting?

Just curious.

I presume not, that's what "Silent Clutch" mean, but I'm still waiting
for rims to build up my own.

Do they make them without the brake?

Yes. The brake is not an integral part of the hub.

You can leave the brake off. That's what I did with my Nexus 7-speed.

If you don't want the brake, we'll knock 15 bucks off the price.

I haven't yet decided whether I'll go with the brake on my new 8-speed.

Sheldon:

I am curious why you are going to lace the Nexus hub to a 650B rim.
Isn't that an archaic size? Why not use the common 559mm instead?

Ahhh, but that's what they'd be expecting.

This is Sheldon "why be normal" Brown we're talking about here.

These wheels are going into a frame or frames made for 622 wheels.
Going from 622 to 559 lowers the bottom bracket excessively, likely has
too much effect on the handling, and requires more heroic measures to
make the brake reach.

It will initially be going on an IRO Jamie roy, though I also have a
plastic Trek frame hanging around that may be used with this wheelset
eventually. Both of these frames suffer insufficient tire clearance,
and I've found both of them uncomomfortably harsh to ride with 622 tires
that would squeeze into them.

SG-8R25, SG-8R20 are 8 speed hubs which can accept a roller
brake.
SG-8R25-VS, SG-8R20-VS are the eight hubs which cannot ("VS"
for "use a V-Brake")
