lockring broke off

so i have been riding my Fixxie for only like 2 days, absolutely love it... but tonight the lockring stripped off while i was backpedaling.. it was kinda heavy but i dont think it was even a skid... i am going to take it to the shop that put the cog and lockring on, but what do you think? what caused this?

If the lock ring STRIPPED off, you have little chance of reengaging any new lock ring threads.

Causes are usually a crappy hub (quadro or what ever that was) or bad installation.

naw i had this exact problem.
i was freewheeling after i backpedaled. i look down and the lockring is dangling and it took a couple of threads with it.
if you can, thread the cog back on, then see if you can get the lockring to thread on. if it didn't take ALL the threads then take it to the bike shop and have them tighten down the cog reeeeaaaaal tight, get the lockring on there as tight as possible, and of course use loctite.

after i found out my lockring popped off i just tightened it all by hand and found the lockring could thread back on but was missing a couple of threads. took it to work, loctite, rotafixed the cog and tightened the lockring, and it hasn't slipped since.

if your bike is brand new i guess it wasn't tightened enough from the factory. my lockring popped off literally a week after i got my bike. surely you felt slippage a few times while backpedaling/taking off as well.

to clarify, the lockring took like 2 rows of threads from the hub but could still catch on to the threads closer to the center.

but as i said, it works like a charm and hasn't slipped since i did this, about a couple weeks ago. and i ride brakeless (until i find a ****ing 26mm cross lever that fits the fat stubby part of the bars)

Riding brakeless on the street with buggered lockring threads. Kids these days.

I have the same wheels, no problems. Did you rotofix the cog first, or retorque the lockring after a couple of uphill sprints? Do this because you will tighten the cog completely as you ride, and *then* you should tighten the lockring again before trying to skid or whatever.

Also, the mechanic at my LBS installed everything when I bought the wheels. He really took his time to make sure he didn't cross-thread the lockring. If the lockring is crossthreaded, it's not going to hold correctly (obviously). Don't use a cheap lockring either -- it's not worth destroying your hubs over a couple bucks (assuming they're not already destroyed).

And install a brake -- at least until you get this problem ironed out. Please.

i dont see why it would slip after what i did. it wasn't THAT stripped, probably 10-20% of the threading popped off but it screwed on just fine after it caught. the lockring isn't stripped, the hub is. my fault for assuming it was tight. it's a formula hub.

just dab tons of loctite on it.

all i know is i've been putting in like.. 40 miles a week (i dont commute, only ride for fun) brakeless and it hasn't budged one bit. i'll keep you posted if i die

yeah mine did not stripp much either, just like 1 thread and squashed another a bit. the mechanic did lather it up with locktite pretty good and took some time making sure it is super tight, i have an appointment to have the shop drill a brake whole for me on my fork so i can put my brake on ... i think i might do some testing tonight around midnight not too dangerous. but until then i shall stick to the good side of my hub .... hurray for flip/flop hubs
