Any tips/stories on fixing cog to a road wheel thread?
I just did the cog/glue/BB ring deal on an old steel road wheel… it seems to hold up so far. any ideas to make it fix better…best type of glue etc?
You mean loctite/thread prep compound right?
Loctite, rotafix and BB lockring should do just fine. I rode a rear wheel with a cog just rotafixed and that was fine.
What snowflake said … rotafix is good, just take care of the frame/paint while you’re stressing it up and don’t expect to be able to skid it hard!
No worries for day-to-day riding.
my surly cog has too much thread to allow for a bottom bracket lockring, so I just greased it up and rotafixed it on as hard as I could
i have been skip stopping and skidding with my 95kg + luggage, no problems so far
Hey Twistie,
Are you running a brake? If not I’d be quite nervous without a track thread. At the track things would be fine though, I’ve seen quite a few ``road" thread wheels down at DISC and I havn’t seen anyone spin a cog of yet (anyone else seen this?). On the road is a different storey though, I had a big cog on the other side of my track/free flip flop which I used to flip just to much around doing tricks on the netball court, I did it have come loose once (bit of locktite), though it didn’t matter because I wasn’t actually going anywhere. I heard some nasty stories though!

I’ve seen people spin cogs off a couple of times at the track, but I would probably put that down to poor mechanical skill. As for the brake nervousness, I’m still pretty firmly in the camp that no brakes on the road is the territory of muppets. Have one and don’t use it, but that one time it saves you from binning it into the front of a car is going to make up for all the other moments of looking choice infront of your hardcore fixie mates.
Agree or disagree, that is my position.

Can’t say I agree with that one, basically because riding at a few km/hr could also save your life, along with the theory that brakeless is a completely different riding style. Though I think this was has been argued for ever hey!
Peace, and ride whatever makes you happy

Just discovered last night that skidding / skid stopping (after I finally figured out to do it) causes my cog to slow undo (i gotta BB as well). Loctite will fix this yeah…?
*EDIT: Just found out what Rotafix is… So Loctite > tighten > rotafix > BB? All set to go?
Do not understand the part about the BB. Please clarify.

BB = BB lockring I suspect.
Yeah, BB = Bottom Bracket lock ring, sorry. 
But this will work?
Here’s my 2 cents worth:
If you are riding with hand brakes, loctite is not needed. Just greese up the threads, rotafix the cog and put your BB lockring in tight. This would work just fine. If it comes loose while you’re doing a skid, you’ve at least got a backup way to stop.
If you are riding without hand brakes, loctite is a good idea. But I would strongly suggest getting a proper track hub of decent quality with a reverse lockring thread.

Seconded
Yeah, I’ve got a front brake, I just want it fix the cog permanently, so I don’t have to worry about it ever coming unscrewed. I’ll try and get some loctite today. Suggestions? Loctite threadlocker blue…? Or red?
Red seems to be the what everyone else is using.
Also, does anyone here know where to buy red loctite in Melbourne?
First up, Loctite is also identified by numbers, not just colour.
But anyway, I wouldn’t bother. I rode rotafixed with a front brake and no lockring and didn’t have any problems.
I wrote loctite THREADLOCKER red or blue. I googled it earlier to see what I should get. I understand there is different types. Anyway, I got some, I’ll try it tonight.
I got red Loctite from Repco auto parts. Maybe try them or Sprint or Supercheap or even Bunnings?
They should have it at the hardware stores tradies use. A stupid question maybe… but couldn’t you just get it welded on? (If you know someone with gear, I mean.)
i picked up some from Consolidated Bearings (CBC) in Airport West. they had a fair selection of the Loctite plus the guys working there were super helpful
