How to Install Cog and Lockring?
 

Hi,

Could someone please give me a quick tutorial on how to put these on? I'm assuming the lock ring screws onto one side of the wheel hub, and then the cog threads on top of it? Is that all you have to do?

Cog clockwise, then lockring counterclockwise.

Oh so the lockring goes on top (on the outside) of the Cog? Do I just need to screw them on tight with enough tension, there's no specific torque settings or anything right?

Nah, just tighten it to the point that the lockring starts to deform and then you're done! :lol:

Also one other question I have is, my wheel has a flip flop hub and on one side, there's 1 column with threads for the cog. On the other side, there's 1 column and then a smaller one with threads on top of it... kind of hard to describe, but which side is for a Fixed gear set up?

I'm guessing the one with the 1 thread side?

No. The one with the column and smaller one is the fixed side. Cog goes on first in one direction, then lockring in the other direction. Lockring has a smaller inner diameter than the cog.

Wait nevermind, it's the other way around figured it out THANKS

EDIT: Thanks theetruscan :)

This is sort of related, but just to verify, for the Bottom Bracket, the side with the Lip on it goes onto the Drive side (with the crankring) correct? And it threads in Counterclockwise?

not all; afterwards hit up a hill/s,

at the top you will have to retighten the lockring

why do i predict that the build resulting from this thread will go horribly awry?

is it still a "prediction" if it's obvious?

this might help:

thanks for the support... to tell you the truth, this is my VERY first time dealing with bikes. To make you feel even more confident in me, all my previous bikes have been around 100 dollars complete (costco, walmart bikes).

For this build, I pretty much just jumped into it. We'll see how it goes, I should be finished tomorrow.

these posts are exactly the reason I had my five year old girl take off her training wheels herself (with my instruction obviouisly) on Sunday.

I realize we dont all have the same up-bringing and all, but jeezoo, we fig'rd this stuff out on our own when we were 10; we just learned real quick what didnt work. I guess part of it we made do w/what we had rather than just buy new stuff when bored. (end of soapbox)

yeah, its great watching her buzzing around w/out training wheels. Her smile makes me miss my StingRay.

I started tinkering with bikes starting at age 6 or so. But my brother, on the other hand, never liked to get his hands dirty, so I did all the mechanical work for him. All he did was just ride.
Therefore, almost a half a century later, if my brother ever got into building a bike from the frame up, I would suspect he would be in the exact same position as this OP. A little tutorial is all it takes. :)

i built up all of my bikes. i build my wheels. it's not rocket science, but you should really have a fundamental understanding of how tools and concepts like threading work before you potentially go and muck up your gear. it's better to have a friend or someone generous at a bike shop or bike co-op familiarize you with the proper tools and mechanical concepts before you put something in a state of disrepair. if it's possible, i'd really recommend pursuing those avenues.

Agreed [after reading your questions]. It sounds like you should have someone who knows what they're doing check it over before you put it on the road..

do you have a lockring spanner? if not, take it to a bike shop and make them tighten it for you.

seriously, if it only looks like it's on there, it isnt and will pop off along with some of the threading on your hub.

i know this from experience.

(1) Go to the auto parts section of a major chain store like Menards or Fleet Farm. Buy a tub of grease. The best choice would be labeled as being for Marine applications.

(2) Apply grease to threads of cog. Screw cog on side of hub with the two tiered threading.

(3) Walk your bike down a big hill and ride up.

(4) Apply grease to threads of lock-ring. Screw lock-ring on smaller threads (counter clock wise). Get it on tight. Use the special tool. If you don't have one, a pipe wrench works pretty well. Don't have a pipe wrench? Put the end of a screw driver in one of the notches and tap the handle of the scew driver with a hammer. In all cases, you will need to brace the wheel against a wall or something to hold it still.

Why did it take so long for someone (tx_what, squeakywheel) to just lay out the process for the guy? No one even mentioned the spanner until tx_what_! Fah.

Yes, you will need to invest in a lockring spanner, or hit up a friend or co-op that might have one. Park HWC-5 seems to work fine for everyone, and hasn't given me any trouble, and you can pick one up for like 10$. Then just follow what squeakywheel said.

i would buy a lockring tool. the pedro fixie tool comes w/ 1 and a 15mm

If you're new to wrenching, TAKE IT TO A SHOP AND GET SOME HELP. Fixed gear bikes may seem simple, but that just means they're easier to screw up. Get a shop to install the cog and lockring.

PLEASE dont do the screwdriver+hammer trick that squeakywheel said. please.

save yourself the trouble and just get a cartridge bottom bracket
