    Crankset Q

    I removed my crank arms and removed each cog to clean. Needless to say when I left them apart overnight I came back and they weren't how I left them
    I don't know how they went back on. It seems like each cog has a specific pitch to it, and if my in head visualization is correct, they should aim clockwise correct?
    I put them all on like this and it seems like the two cogs, largest and middle are much closer together than the middle cog and smallest!!

    I know the outside one is on correct, and when I flip the middle one around it doesn't fit correctly. Are they supposed to be offset like that for some reason or what can I not comprehend about this setup. God I would never think 3 gears could be so confusing.

    the rings have markings on them for orientation, in between 2 of the bolt holes is a little nub that sticked down this nub gets lined up with the drive crank arm, and the big ring has a kinda button thing that sticks out this points to the outside of the bike and lines up with the crank arm, its to keep a dropped chain from jamming in between the ring and the crank arm, the pinned and milled parts of the rings go facing inside, usually the tooth number markings face inwards, on the big ring whatever side looks fancier faces outside

    I got it all together with thread lock and everything. Clean as a whistle.

    fyi the only chainring you need to pull the cranks off to clean is the little one, so if you don't need to clean ur granny gear you can just can puzzle the middle ring around the spider and save yourself some work, thats what i usually do and then just wipe off the granny gear with paper towels, although now that i have external bb cranks on my new bike removal isn't as big of a deal, don't have to break out the crank puller and the torque wrench, w/e i'm still lazy

    You put threadlock on the chainring bolts on your bike?

    How is that a good idea?

    thread lock isn't needed, but it won't really hurt anything, may just make it harder to get bolts out later, threadlock is an anti-seize compound as well as a thread locker, so will make sure teh bolts don't seize up or rust together/whatever happens between threads that makes them hard as heck to get undone after a year or w/e, technically you want to either grease or threadlock almost all bolts and i can't think of 1 on a bike that shoudln't be greesed (there are parts you don't grease/threadlock but not threads) we are all just too lazy most of the time to grease em all

    the only thing i can think of that you don't wanna grease/threadlock are the lug nuts on car which i've heard you don't wanna grease cause it changes how easy they are to tighten down and the torque readings are for dry bolts, so you end up over torqueing (assuming u use torque wrench like you should be) that can lead to a whole mess of problems from breaking hub bolts to cause ing rotor warp (or at least so i've been told)

    The bolts had threadlock on them already so I figured it was ok. I put medium threadlock back on them. Keeps bolts snug but its still easy to get off.
