So the original lockring that came on my formula hub has slipped off 3 times when I skid/skip stop or make an attempt at either one. I took it to my favorite bike shop and one of the guys told me it looks like it’s due to the hub not having enough thread going through the cog and lockring. So he suggested getting a new cog and lockring which I did and it hasn’t popped off yet but every now and then during a skid/skip I feel some slipping.
So do I need a new hub or what? Maybe I’m being a little dramatic but I’m ready to end this nightmare. Please give me some good advice.
Find a new shop.
Tighten the shit out of that crap. If it still doesn’t catch, get a 1mm Bottom bracket spacer and put it between the cog and hub or cog and lockring depending on which gives a better chainline.
i stripped 2 formula hubs in a month using a cheaper cog and the lockring that came with the hub. check the lockring to see if there’s any sheared metal in the threads, and examine the hub to make sure it isn’t stripped. i knew the hub was stripped but tried it anyways, and the lockring came flying off the first time i offered any resistance. if the hub is stripped, it’s done.
i got a better cog and dura ace lock ring, greased the hell out of the hub, tightened it myself with a chainwhip and lockring tool, and haven’t had a problem since.
also, if you feel the cog or lockring slipping in any way at all, stop the bike! if the lockring or cog are loose, there’s a gap and the cog will tighten when you pedal, and losen when you resist the pedals, loosening the lockring more and more. so the more you pedal and resist when things aren’t tight, the more you’re potentially stripping your hub by it moving back and forth, back and forth, back and forth…

its like wearing nothing at all, nothing at all, nothing at all,nothing at all, nothing at all, nothing at all, nothing at all, nothing at all, nothing at all, nothing at all, nothing at all, nothing at all,
where do you go? blueline? they shouldn’t let you down
LOCTITE. the red shit. rotafix the cog on there with dabs of loctite, and then dab loctite all over the lockring. it’s going NOWHERE.
oh and my formula hub had like 2 rows of threading removed when the lockring popped off. more than likely yours is slipping again, so rotafix it on there as tight as you can with tons of loctite. i did that and skid wrecklessly for months and haven’t felt a bit of slipping since.
and is PG getting those vans 45lx fixed? fuck everyone else i like them.
People constantly report problems like this when they use cheap cogs and lockrings. If you’re not using something at at least Dura Ace level, then that might very well be the problem.
After that, make sure you’re using the proper tools for installation. Do you have a lockring wrench? If not, buy one, or else don’t skid. If you’re trying to tap your lockring into place with a hammer and screwdriver, or some other wacky method, that’s a stupid idea and you should stop. Grease your hub threads (both steps), rotafix the cog on, tighten the lockring with the appropriate tool, and you should be ok. Loctite is overkill.
you should NEVER need loctite. either rotafix the cog on and then use a lockring tool to get that shit super tight or get the cog on as tight as you can and haul your ass up the biggest hill around and without resisting at all stop and tighten the lockring on.
using a shit cog will strip your hub every time. why cheap out when you can get a DA or EAI for like $20?
i think my hub is starting to strip, not surprised its a shitty stock one
it only happens right after i skid sometimes and when i try to accelerate by starting a stand up sprint
Thanks for the help, the cog and lockring I’m using now is surly. It’s what the guys at the shop recommended I get, since then I’ve really been babying it until last night I went on a pretty long ride and at one point while accelerating forward I felt slippage. Since I was so far from my house I offered no resistance until I got closer to home then I pulled an assload of skids dogging it to see if it budged and it didn’t??? So I don’t know if it’s ok or not, I don’t know what my next move should be.
I make all smaller adjustments to the bike myself but for things like this I have to rely on a shop doing the work and being able to trust their good judgment.
