can someone describe to me the symptoms of a hub thats starting to strip?

im not familiar with this and im afraid it might be happening.
also, how dangerous is this? i know ill have to fix it, but should i just stop riding all together until its replaced?

can this be expected to happen with every hub over time?

thanks much.

uh, how do you mean stripped hub?

the lock ring won't tighten down all the way?

sorry. maybe stripped hub isnt what the problem is.
ill try to describe what im experiencing.

sometimes if im pounding up a hill or doing short caution skids i can feel something loose. it feels like the cranks move without the wheel stopping or moving (depending on if im skidding or pedaling hard)

its not a loose chain and i just replaced the whole crankset.

i though maybe (somehow) my cog was slipping.

yeah. thats the problem. cc700 told me that sometimes when the threads strip they just strip a few at a time, allowing some slight slips before another thread catches it.

bummer =(
i have quando hubs...are these cheapo?

Is your hub slipping? Not necessarily. If both your lockring and cog aren't tightened enough, you'll get slipping when you accelerate (cog slips forward until it's tightened down all the way) and when skidding (cog untightens until it's caught by the lockring and the lockring gets tightened down).

Is your Quando hub junk? Probably. Most people don't give those or the Suzue jr.'s a second-thought because Formulas are so much more superior for practically the same price.

hmm... have you tried tightening the cog down with a chain whip and then tightening up the lockring?

also, you could take the lockring and cog off and inspect for stripped threads.

I don't know anything about the quando hub, sorry...

ah, didn't see the other poster, yeah... that's why I'd try tightening the cog and 'ring...

good words. thanks very much. ill try and tighten those up and see if the problem persists.
thanks!

I stripped a quando hub once upon a time. Except it was fine till I skidded hard one day and it just spun right off like there was no lockring on it. Sucked bad.

quandos are like butter. a friend of mine stripped two.
what kind of lockring are you running?

when i stripped my cog it was exactly like what you're describing. if it is stripped, you can still get a lot of use out of it. jb weld works great, the only problem is that once the cog is on there it's on there. pick your favorite size cog and go crazy.

im not sure what the lockring is. a no name. i got it from a shop for free.

i wish i had the tools infront of me to try tightening it all up. i guess i wont know until i do that.

to tighten the cog, i can just pound up a hill, yeah?
then tighten the lockring after i do that.

quando =

Aluminum and steel don't mix if your using some crappy stamped out steel cog it could definitely strip your hub. Me personally i use an alloy cog from EA its a bit pricey and will probably wear faster but it feels great and i no its not going to strip my hub.

I'm having this same problem. Any way for me to tighten this stuff on my own? I'm really new to all this (just learned what a lock ring was reading this thread.)

you can do it yourself without specific tools, but if you don't know much about it you might wanna bring it in to your lbs an have them tighten the stuff.

you can tighten your cog via rotafix method.
and then you can tighten the lockring with a screwdriver and a hammer. put the end of the driver (preferably flathead) into the notch on the lockring, bang it with the hammer to tighten. remember: lockrings are reverse threaded--i.e. lefty-tighty, righty-loosey.

double post.

I'm going to buy the tools to fix the problem myself. Chain whips look pretty standard, but Nashbar has like 5 different types of Lockring tools. Anyone know what I should get for a Formula Lockring?
This is what it looks like:

The description says "Shimano Style" and looks similar to the Dura-ace.

Once a hub has stripped at all it's pretty much done, you can't put the metal back on the threads.

The cheapest lock ring tool that works on track stuff (other than making one out of a pair of channel lock pliers with a grinder) is the Park HCW-5. Some people can get the single pin end to work, though I find the middle pin of the 3 pin end to work best.

If that's a response to my question I don't think my hub is stripped. No advice on the tools then? This is what seems to be happening:

"Is your hub slipping? Not necessarily. If both your lockring and cog aren't tightened enough, you'll get slipping when you accelerate (cog slips forward until it's tightened down all the way) and when skidding (cog untightens until it's caught by the lockring and the lockring gets tightened down)."

the chain attached to your bike and a hammer and screw driver. It doesn't have to be insanely tight, just really tight. If its not tight enough you'll know when you take it on your test drive. I just put the cog on and hand tighten it, then put the lock ring on but only a couple of threads. Then I mount the wheel, lean against a wall and kinda jump on the pedal, then I rotate pedals forward 180 degrees and do so for the other pedal. After that thread the lockring on all the way and tap it with the screw driver. No need for new tools. BTW make sure when your tapping it you're pushing the lockring around the hub and not the metal part of the screw driver into the handle lol.

Is JB weld that strong????

You should've seen red loctited cog on quando.

I have never used JB weld before... so i have no clue. And I cant get my hand on it cause there is no dealer down in Australia. I think I should get some off ebay and try it out.

I used JB Weld for the first time a couple weeks ago on my bike in the driveline, don't know words to describe where, and its held up perfectly so far. Welded steel to aluminum, or just filled in the gap.

jb weld is srsly THAT strong. i jb welded up a cog to a stripped hub and rode it for about eight months until i taco'd the wheel.

i really recomend it. mix the two parts in a plastic bag... sandwich style. then cut a hole in the corner and apply the mixed jb weld to cog and hub. put it on as tight as you can with your hand and then let it sit overnight.

tomorrow you have a new(ly refurbished) hub.
