Has anyone used a cog that mounts to a rear disk hub?

sloppy robot

vomitron made one, and rode it, but then he quit bicycles for summer camp and ditched all his friends.

ya!

Matthew, PLEASE tell me you're planning to have some made, affordable, and available.

I will be your number one fan, and even forgive the threadless fork on the P/R. snicker.

Terror_in_pink

oh kiecker made one too

Toolshed

I made one once but the whole dishing process made it almost not worth it.

Actually, I still ride 200+ miles a week, I just have to squeeze it in at odd times like real early in the morning or later at night around my 'hood.

If you want to get down to it, I just ditched my friends for summer camp and water polo (I'm coach, not a player)...and drinking heavily. You losers always called it quits at like 11pm.

i'd be interested if someone made them- even just drilled out some cogs. I think spicer cycles will make them, but it's a special order sort of thing.

I ran with one for awhile, but while the concept is good, my execution with a hand drill was not.

I will buy 16,18,19 and 21 now or swap for screw on cogs of the same teeth count.
I know how I want my next wheels for my next bike:
soul-kozak (google) front disk hubs (130g each) front and rear; front mounting a disk and the rear mounting a cog, carbon tubular climbing rim (24-28 spoke), drive (disk) side 2 (3 if possible) cross; the other side radially laced. An adapter for fork ends to mount 100mm hub at the rear.

If I feel spendy I will have another wheel like this but using soul-kozak diskless front hub for brakeless rides.
And I already have a frame for this bike

Less fancy hubs, more cheap real track frames.

I have a singlespeed cassette MTB hub with a disc mount that I bolt a cog to, resulting in a flipflop fixed-free hub. Switching cogs is much easier, and I never have to worry about destroying weaksauce track hub threads.

Kogswell

The making is done. The availability is nigh.

It's that pesky affordability that I'm struggling with. Any ideas?

Kogswell

Don't get your skirt over your head.

I'm working on it.

And by the way, what exactly IS a REAL track frame?

Kogswell

Thank you.

What's weaksauce?

Kogswell

Why not use cheap, 110mm BMX disk/splined hubs?

LóFarkas

Sell it cheap.

I had splined hub which I converted to fixed with the adapter I machined.

some description is here (see post by vobopl)
Edit: first link corrected.
Why not?
1) splined cogs, unless you go for expensive, wide base ones cut through the casette body splines.
2) splined casettes, unless very best, do not have the splines co-centric with the axle
3) the play between the cog and the splines is unavoidable
4) I have no use for fixed/free capability provided by disk/splined hubs

I am all for bolt on solution, with bolt circle co-centered with the axle. This is not an important design feature for disk brakes - the braking surfaces of the disks are wide enough radially. The Kozak hubs (he makes all kinds of them) are perfect in that respect. Besides, I am weight weenie and his hubs are 130g disk/ 56g diskless front

Kogswell

Huh.

Interesting.

I spun that cog on that hub and it seems pretty square.

Must be that Taiwanese 'gno hau'.

Isn't using an ultralight front hub as a rear a bit iffy? I mean, presumably, rear hubs are heavier for a reason... they receive a LOT more abuse. A front hub, even in an MTB (they all have front suspension nowadays) has an easy life. Won't it break if you put it in the rear? If a hub is considerably lighter than the low-flange DA, it's sort of suspicious to me.

Of course, the disc mounts will take the drive loads easily, and if the flanges are the same size as the rear... Dunno.

vobopl

That's what I am counting on - the mounts AND the flange have to take the drive load if they can take disk braking load.

Me neither. Now accepting bets.

I don't use one, but I want one real bad....

I've got a downhill racing front hub I've been dying to do something with just sitting here, and a paycheck that really doesn't want to be spent on food - if someone points me to a cog that will either A) drill out properly or B) is predrilled, I might just give it a shot.

I'll even put it on my CX bike, that'll test it out pretty well.
