Stripped lockring threads

i ran the same hubs for ages on my polo bike, swapping cogs frequently. no problems.

so any hubs take into account ultra low polo gearing for their threads? bolt on better for GIs lower than 45?

I had a problem with the lockring threads being a bit too strong on a SystemX hub; I managed to strip the sprocket threads starting off at a light.

Given the quality of SystemX, Ambrosio, etc. hubs, it's not surprising that there would be a massive variation in quality from hub to hub. Some will last for years, while others will fail quickly.

formula/system x/ambrosia rims are cheap, but fucking both lockring threads, is more like user error. there is tight and there is tight. only thing that i can think off is if you used the cheapo alloy lockring, which should be binned and never to be used.

I like my alloy lockring... saves me a gram :) but okay, it's got a small "C" stamped on it.. so I guess it's not cheap.

From a slightly different angle then: if you were going to build a strong bike for serious daily street abuse, would you use cheap track hubs? In fact, is there anyone out there doing just this long term with no problems? See I'm getting the message that if fitted correctly, the lockring threads are very very unlikely to fail, so no not reason not to use them? And no reason to consider the alternatives mentioned above?

I started my fixed "life" with a (very) used wheel, with an on-one hub.. used it for about a year, changed bearings in it twice, then changed to a Miche (purely for the bling-factor)..
This winter I have been using a used set of wheels with "Ambrosio"-hubs, one side lockring thread was smashed when I got the wheels, the other side was fine though.. The spoke tension was fucked up as well and I had to re-true the wheel. So, might indicate a previous user that wasn't that much into the technical stuff.. :) Changed the sprocket on the wheel and didn't have any problems with the other side..

One problem with the cheap hubs is that the axles rust, and so does the nuts.

It's a myth.. You'll not strip the threads running a low gear.

what are some hub brands that have bolt on cogs?

Word is that converting a shimano deore XT front hub to rear with an axle kit is a strong and affordable way to do it.

Whats best to put on the threads to stop this from happening, anti seize, copper grease, or loctite?

None of the above.

A light smearing of grease, I use the red teflon stuff. Copper grease is virtually the same as anti-seize so I wouldn't recommend it, infact, it's minging stuff, I wouldn't put it near my bike.

Bit of a dredge but, my arse you did.

Just any old grease then? I've got loads of agricultural type stuff lying about which would save a trip to town if I could use that.

Is that a no to anti seize/copper grease to anywhere on your bike then, I was planning on using that on the bottom bracket threads.

Personal preference perhaps but I've never had a bb I've installed with teflon grease be a pain to remove.

I find antiseize, copper slip in particular to be exceedingly difficult to remove, it just spreads/moves around and is quite impervious to gt85/degreaser etc.

In automotive applications it's resistance to temperature etc might make it worth the hassle but for bikes it's just overkill in my opinion.

Your agricultural grease will probably be better than nothing but I'd shell out a few quid on a tube of teflon grease from Halfords or such. I use it for everything, seat posts, hub bearings, bb threads, cog/lockring threads etc etc.

normal grease, grease all threads on hub and sprocket and lockring all way round with your finger. fit, tighten to about 30-40nms. ride!

teflon grease is good, i agree. and if you can't get lockring/sprocket on with your fingers initially the threads may be off, and using a tool will fuck them up

Cheers, I'll get some teflon grease

^and both sprocket and lockring go on fine, the hub is new
