Smallest driver on a Tuffnek Hub?

[soty]

Very quick and simple question.

Had a look around but can't seem to find any info. What is the smallest driver you can fit on a single speed Tuffnek hub?

I ran a 13 previously, and currently have a 16, but i'm wondering if it can take 12?

Thanks in advance.

[soty]

Well in the meantime i've actually found the answer. Yes 12 is possible.

How about 11 tooth?

as long as the pattern is the same on the cog it should work but you may need to buy a low profile lockring oddesey make one

my mate has an 11t cog its made by poverty (dans comps brand)


is it possible to put one peice drivers onto the tuff nek ss hubs ?

I heard when i bought mine (cassette) you could some how run a 9 tooth BMX one with some adapter or something on it.

Dont quote me on that as im not sure!

EDIT: I will look into it now and see what i can come up with

[julianwisbey]

why would you run a 9t you cant get 18t sprockets yet

[soty]

Yeah 9tooth is a little bit drastic at this stage. I don't have much faith in strength there, they would shred up under the load.

the smallest possible is 12 told by a awsome guy at lbs but corect me if im wrong it may be possible to get a new freewheel that has a smaller cassete part were the driver goes on.

Im talking about a one peice driver, not a sprocket.

on the bmx hubs that have the 14mm axle they can run a thing called a single piece driver. they way they work is you current setup is a tooth that is held onto the freewheel with a lock nut. the freewheel has the engagements built into it. with the single piece driver is you buy the right tooth you want and that has the engagements built into that. so you take out you freewheel and put in a single piece driver. the driver is one solid piece of forged something probably steel so they are supper strong. unfortunately they don't make them for a 10mm axle hum so where stuck with the lock ring version.

its already been covered BUT you could run a one piece on a toughnek as they look to have the same driver as the bmx hub but it has a 10mm axle

you could run the bmx 1pce drivers buy getting new driver bearings or getting someone to machine you up some spacers

don't bother though as if your running 26in wheels an 11t is going to be as small as you can possibly run as 22t sprockets are the smallest you can get at the moment

The guys at ECI can switch the bearings in a BMX driver to suit the 10mm axel, you just have to ask them ;)

as mentioned above there's not much point if your running 26" wheels. cassette cogs are sooooo cheap by comparison.

also if you decide to run an 11:22 or a 12:24 setup: be aware that sometimes the chain will rub on your frame or have really bad chain-slap.

It seems i've forgotten to add. I'm only looking at the 11 and 12. Nothing lower as i'm running 24" wheels. So i'll be running a sprocket around the 25/28/30 mark.

Thanks for the info guys, I think i'll just go with 12tth.
