Having that 8 speed hub looks superbly appealing to me!

thoughts?

JoshG

ugly..

Um, an eight speed hub has eight speeds...none of them are fixed...

But, if you're talking about putting that hub on an SS frame, just keep in mind that that hub comes spaced at 130mm, and most SS frames are 120mm. Not sure if you can re-space that hub specifically, but it looks like you probably can.

Irony FTW!

Hmm.

Yeah, it wouldn't be a fixed gear bike anymore. Any bike with horizontal dropouts or track ends should be suitable for an internally geared hub (IGH) like the Shimano Nexus 8. There are a number of bikes that come stock with such hubs too. Just a few of the manufacturers that make bikes using these include Swobo, Trek, Bianchi, Felt, Brodie, Novara, Breezer, and Specialized.

I'm running one on an early 80's mountain bike frame with horizontal dropouts and 126mm spacing. There isn't much to say about it other than it's a great setup except for the shifter options. However there is a way to use an old 8 speed lever with an inline travel agent that works quite well. Read the reviews and buy the premium "red stripe" version or the Alfine.

You could bend a steel frame out that extra cm or what have you but I would not
bend an aluminum frame that much.

Just buy a CHUB and stick with one gear, no cables and the same swollen look

jjvw

The CHUB would only work if it weighs in at 4lbs. Otherwise your suggestion is silly! :-)

Might as well get a Rohloff 14 speed hub. It's better looking than the Nexus hub and offers nearly twice the range. https://www.rohloff.de/fileadmin/rohl...4_facts.en.pdf

It's also 15x more expensive. But from what I understand, you definitely get what you pay for with the Rohloff.

the nexus sheldon ran was not fixed. the bike was previously fixed and he converted it to a nexus 8 freewheel. this was explained in the other thread you posted it in. did you think starting a new thread would make it true?

BF GB IRO RR w/ Nexus 8 hub. IRO's compromise spacing of 132.5 on the RR fits the hub like it was built for it.

You know, Irony is just IRO-NY, but IRO is in Massachusetts. Go figure.

IRO-MA would describe someone sniffing their own farts.

PS--the NuVinci hub accepts a standard freewheel on a cog adaptor; the freewheel lives outside the actual IGH body. Could not possibly be too hard to have a lockring thread fabbed on the existing adaptor to use with a fixed cog. Or maybe just liberal amounts of permanent loctite to figure out if it would work. I emailed the mfg about the possibility, but never heard back. The transmission works on friction, so it might slip when locking up the rear, but it is also insanely heavy duty, so maybe not? Infinitely variable gear ratio fixed cog anyone?

ive done a few bianchi san jose w/ nexus for customers at my work. we call it the san joseight special. heh. I like the sram imotion 9 alot too.

mconlonx

I thought IRO was in PA? Which would make them a moon of Jupiter: IRO-PA

Kol.klink

i think internally geared hubs are great i just laced up a 40-hole deep-v to a 1967 sturmey 3 speed. The shimano alfine/nexus . So is the sram stuff is nice, anything pre nexus is to be avoided like the plague, i'm awaiting the new 3 speed fixed hub if it ever arrives...... although i have not dealt with any new sturmeys i have mixed things.

bbattle

You are correct; IRO-PA it is. A good thing, too.

Ken Wind

I've heard bad things about the older Shimano IGHs, but what's wron with the SRAM?

The Paper Boy

I wouldn't think it possible to be more misinformed.

Track frames are generally 120mm. There are plenty of frames with spacing at 130 - 135mm that can be used with a Nexus hub. Surly's Cross-Check, 1x1 and Karate spring to mind. As did the Rob Roy.

And the Nexus hub was spaced at ~132 so it could swing either way.

Even though i've already got derailleurs sitting here for my next project, I keep looking at frames and that damn nexus 8 hub and am tempted to do that instead! I've considered the bianchi san jose or any of the other vaguely cyclocross style frames (cross check, specialized single speed tricross, etc.). The only thing that makes me hesitate is the extra 0.5 to 1.5 lbs. in weight. I know I can try to make up that weight elsewhere with light weight parts, but then it might feel even weirder having all that weight in the rear hub.

jjvw

On my set up with the Nexus 8, the only time I notice the added weight on the back wheel is when I am carrying the bike up a flight of stairs. It is a tiny bit more awkward than my other builds. But, when I'm on the street I would never know.

they remind me of wagon wheels
