So my new Odyssey Keychain in making an ugly cracking sound when back pedaling... I don't know why but it's in the same spot every time... so I'm thinking maybe it's defected and it cracked... idk here's a video if you guys can help!smile

Are the master pins tight and the whole chain lubed? Is it the master pins making the noise? If they're on the sprocket or driver when it happens, it's probably a master pin making the noise. Does it happen at all when pedaling forwards?

Wouldn't be surprised with how thin they are around the pins..

If it's a new chain and old gears, it could just not be seating correctly & may need to be worn in over time.

Also make sure all the links move freely and aren't seized together. Make sure the master link isn't overly tight, stopping it from moving properly. If it seems to be fine in those regards, check each link individually for cracks/flaws.

Yep master pins are tight, and the chain is lubed... and when it makes the noise the master pins aren't on the sprocket so it's not the masterpins....

It's a new cgain and new sprocket and driver... so it's not wearing in... and it's a new noise, it just started happening today...

Could be everything wearing in. Chains starting to stretch and could be wearing on the new gears.

The thing is it just started making the noise today... the last couple days it was perfectly fine...

When you put the chain together maybe where you cut and attached the chain together/to the master pin it left a stiff link? And it just started now because the chain stretched slightly?
Just an idea.

Hmmm

Right. Takes time for the chain to start stretching.

I'd say if you can't find a cracked or stiff link, just try to ride it out. Keep it lubed.

My hollow key chain makes this same noise periodically when back pedaling "off" the bike and using my hand.

It doesn't do it while riding, so I don't even worry about it... I'm pretty sure it's just the chain moving around in the sprocket, because of the lack of constant tension (creating the sound you hear).

Also, if you ever crack, break, or even need to lengthen your key chain... You can always repair/ fix it by just using extra master links.

It masks the noise when I'm pedalling amd backpedaling while riding the bike....

Weird, have you already checked for a tight spot in your chain?

Usually, before you tighten down your sprocket you can move it slightly (up, down, forward and aft) and it will help with your chain tension. It's a pain in the ass and can take a long time, but I believe I had to do it when I installed my new key chain and sprocket (in order to get rid of that noise while pedaling).

That sounds like a good idea to move the sprocket, but I have a spline drive so it doesn't necessarily move on the spindle lol

Ahh... I see that those cranks are both spline & bolt drive compatible, so you must have the socket drive Fang sprocket.

Can you move your wheel a little forward and loosen up the chain to see if it still makes the noise, or are you slammed?

Yeah I can move the wheel forward more... but then the chain is super loose... idk I'm not hating on Odyssey I'm sure Odyssey will send me another one if it continues... considering I've only ridden the chain 4 times...

Does your sprocket have excesssive wear marks on one side?

Is your wheel centered in the rear triangle perfectly?

The fang sprocket is a pretty square toothed sprocket it might just be rubbing on the chain.

What rear hub are you running with it?

All my issues with the chain have been chainline related. The chain is burlier and less able to flex side to side so it chunks up the softer aluminum parts. That and some broken master pins but thats from overtightening them I feel.

I do get really bad tight spots in my chain but that's because I managed to bend a guard sprocket haha

No the sprocket is still pretty brand new... I only ran a bluebird chain with it for like 2 weeks while waiting for my Profile Mini wheel... so the hib I'm using is the Profile Mini hub now... which is brand new... but the pins aren't over tightened at all... just all nice and snug... and the chain line is pretty spot on... idk maybe it's just a faulty chain that maybe had a flaw in the machining process... I may just pick up a new one from my LBS, or just hit up Odyssey...

Word, I'm sure it would be super loose, but i'd just see if the noise happens to go away (doesn't have to be permanent).

When all else fails hit up Odyssey for sure... I'm sure they would just ask you to ship yours out first, or vice versa (I'd keep your master links as spares).

Dude let everything wear in before you freak out. It's really not uncommon for the drive train to make noises like that, especially when everything is brand new. Also consider that the keychain has oversized rollers, which means there's less space inbetween them for the teeth on your sprocket/driver. What youre hearing is likely just your chain rollers popping into place on your driver/sprocket. After awhile they will wear on the teeth a little bit and it will stop. Aslong as there isn't a cracked/overly tight link, just keep it lubed and keep riding on it cautiously.

Id say if no noticable extra wear is occuring, you might be fine, keep an eye on it though. Its good that you take notice to small changes in your bike! Stay like that, warning signs can be small sometimes but if you ignore them for too long bad things can happen at a bad time.

Like others have said it takes a while for things to mate. It does seem odd that it didnt start off that way though... have you hit it on anything or landed on your sprocket?

Well I have been doing grinds now that I have pegs, bit I grind on the left and my drive train is on the right... and I can't recall hitting the sprocket on anything... I haven't really messed up too many grinds yet... just my chain stay has taken a beating lol... but I'll gibe it a little bit I guess... it's just so freakin' annoying lol...

You said it's a new hub too right? What makes you think it's the chain and not the hub? When hubs break in they can pop and skip a little.
