I've been waiting more than a year for my Boone ti cog. I've given up on it. How much and how do I order?

Hell yes I'd be down, though I can't figure out why he says 9-speed can't be used with it, as a PC-58 is 3/32" (unless I'm wrong).
Cost?
Also, wasn't someone on here trying for the same idea?

found this on mtbr forums
the website:
https://tomicog.blogspot.com/
the purpose:
To supply disc fixy cogs to a small niche market
in order to cover my race season 'budget.'
Need to add the purchase option/shopping cart dilly
to the website, then it'll be good to go. Target is to
take orders and begin shipping the first production run
first/second week of January. Final price is gonna
be maybe $25, maybe $30 ea, $4.95 to ship up to four.
Will spam again when it's all official.
peace,
Tomi

I got in a Pisgah Mountain ride Sunday on an early pre-production model of the Tomi-Cog. Gotta say it was hiccup free, and it will be well worth the money if you're looking to try off-road fixie on the cheap.

I drilled one out myself.. but its definitely off center. I would readily dish out some money for a 6bolt disc cog that doesn't have me waiting a more than two weeks
if my Boone cog ever does come... I will immediately take it over the Paul comp and ask if he'd be nice enough to make me extras (backups.. if you will)

I guess I never got around to hooking up an avatar on bikeforums.net, but yes I am the guy who wants to be Bruce Campbell when I grow up.

I canceled my order for a Boone Ti cog and ordered a Tomicog. I emailed Boone, and after having ordered it 9 months ago, they still don't have a time frame on when it will be done. Definitely not worth the wait.

Ok i just received mine in the mail today and then I went out and picked up some bolts for disc rotors. one thing that has me puzzled is that the bolts are considerably smaller than the holes in the cog. Is there a second type of disc brake bolt that has a larger flange near the bolt head that would work better and fit tighter than the ones I have?

I got my Tomicog a week ago and scrounged up a mix of old stem bolts and bottle cage bolts, which worked just fine.

Have a new cog from Tomi. They are really nicely made.
The holes "stretched" one the one I made. I think I overheated the cheap steel when I drilled it. By the way, 38x18 is too big for the steep singletrack around here.
Anyone have a 5 bolt 110BCD silver 34 or 36 they want rid of?

With the wheel dished symmetrically, I get about a 46 mm chainline. That works for me since my crank chainline is 45.5 mm. A true rear disk hub will give you a wider chainline than that. But there is really no reason you can't get the proper chainline, given the multple ways you can adjust it. (1) you can redish the wheel and adjust axle spacers, (2) move your bolt-on disk cog towards the dropout with some washers, (3) move the chainring with chainring spacers, (4) or change the BB spindle. You can usually cure a severely f'ed up chainline by adjusting the first three things without having to buy a new bottom bracket.

wow, looks great, i have a single sided track rear that I would like to replace with a tomicog (which I have) with a front mtb disc hub re-axled to work in the rear. If now ill go with rear mtb SS hub, but I have 120 rear spacing, what is your rear spacing? MTB standard?

Is that helicoiled, or a tandem crank?
