Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer?

Please help a n00b not die re:lockring problems

I am in the process of converting my first beater. Everything has gone smoothly...except for the lockring business. The cog came undone while I was fooling around in my apartment checking to see if everything was secure enough for the road. For some reason the lockring will not screw on all the way and there's a good 1/4" gap before the threaded step-up. The wheel was built out of scraps by someone I solicited on craigslist, so i don't know what specs of the rear hub other than it's a flip-flop. Did I buy the wrong size? Did I screw it on the wrong way? Do I need to purchase some sort of lubricant to force the lockring to screw on the rest of the way? Should I give up this project and cry?

These are the best shots I could provide to explain my problem.

Is that a spacer between the hub flange and cog?
If so, that's why your lockring wont thread all the way on.

There is nothing between the cog and hub?
That looks like a ****ing huge gap in the first picture.

What kind of cog and hub is that?

-yes, I'm tightening to the left.
-the lockring is something generic I picked up off ebay.
-the threading appears to be the same except the lockring only goes 75% of the way.
-the cog is also off
ebay
-I'm assuming I have a suzue basic flip flop? No clue...someone built this for me and I can't get ahold of him to ask. I'll upload a shot of the markings as soon as my server gets its act together.
-Yes, this is messed up! My LBS won't help me and I just want to do this right!

thanks in advance for all the help.

thats not a suzue basic.

you probably have mismatched/mangled threads on either the hub and/or lockring.

I am going to say you do not have a track hub.
Is it certainly not a Suzue Jr.

Your LBS wont help you?
You're in Chicago, go to a differnet one.
Go to Yojimbos.
But, I don't think there is much to "help" you with, other than helping you buy a new hub.

So I just assumed that it was a track hub and I was never told any different. What lockring and/or cog do I need now?

I've been to upgrade and boulevard, but no one seems to have the patience to deal with someone who's new to the game. I'll give yojimbos a try.

Correct me if I am wrong, but that is a BB lockring.
You need a track hub lockring.

The hub does appear to have 2 sets of threads, so I guess you're good to go with that.
But, yeah, new lockring.

That is weird. There's way more space between the end of the threads and the hub flange than I've ever seen...definitely doesn't look like any track hub I've ever seen. The treading could be anything...your cog and lockring look fine...but this hub isn't normal.

Is that the old Shimano logo?

The etching is worn but it could possibly be an old shimano hub.

Is it confirmed that I'm idiot who bought the wrong lockring?

i've found the wrenches at Rapid Transit on North to be patient and helpful, even with my noobish questions.
Maybe pick a weekday when the place isn't packed with weekend warriors.

that IS the old Shimano logo. I've never seen a hub like that before. I recently had a hub strip because the threads that the cog went on were too long, so the lockring didn't hit the cog. I had to put a spacer in between the cog and the hub. That seems to have done the trick. I would first inspect all the threads, grease everything, try again, and if that doesn't work, try a different lockring. If you come in to Rapid Transit tomorrow I can try to help you personally (my name is Sam, I have a mohawk that looks more like a mullet). I don't think we have any lockrings in stock, but I can certainly help you determine the problem. It's very difficult to diagnose things without touching them.

Take it to Marcus, he'll probably be interested in just seeing the thing. Pretty wild old hub, though whoever built the wheel doesn't know WTF they're doing (valve stem hole in wrong place).

Does that lockring not look like a normal hub lockring to anyone else?

I hate to say it, but that is quite possibly the ****tiest hub I've ever seen. Now that I'm done being a jerk, I hope everything works out. I'm going with its not the right lockring.

another way to keep yourself from dying is to get some clips and straps.

i'd help with the hub, but i suck at giving advice when i can't do the whole "hands on" approach thing.
