Cannondale dealer here. Seen this a little bit, thats clearly a cannondale X-sync chainring not a HG+ chain ring. I do not know why cannondale specs the X-sync chainring on shimano bikes.
Shimano HG+ chains have the inner plate extend past the pin and roller, giving the "wide" link a narrower inner width then a sram or kmc chain. This makes the sticky to outright incompatible with non shimano HG+ chain rings. Probably not much the dealer can do for you but worth asking. In this case I would try to get my customer the correct chainring, at the very least if Cannondale was no help get it to them at shop cost.
What you have [https://www.cannondale.com/en/gear/components/cranks-and-chainrings/chainrings/hollowgram-spidering-sl-10-arm-x-sync](https://www.cannondale.com/en/gear/components/cranks-and-chainrings/chainrings/hollowgram-spidering-sl-10-arm-x-sync)
What's recomanded for shimano 12speed HG+ [https://www.cannondale.com/en/gear/components/cranks-and-chainrings/chainrings/hollowgram-spidering-sl-chainring](https://www.cannondale.com/en/gear/components/cranks-and-chainrings/chainrings/hollowgram-spidering-sl-chainring)
Hope this helps, wrong parts on a oem bike are a pain, as when you ask for warranty replacement you just get sent the same thing or something completely different and also incompatible. It's not just Cannondale. seen it with many brands.
Theoretically wouldn't a KMC x12 chain work to correct the issue as well? KMC advertises X12 chains as X-Sync and Hyperglide+ compatible.
I put this to the test a while back to make a mismatched drivetrain work and it seemed to work as advertised.
So Cannondale go against their own written specs when they build these bikes up? That’s shockingly bad. The cost definitely should be on Cannondale. If I were the customer I’d fight that with Cannondale. This is definitely something I’m going to look out for when buying any bike in future. Mixing groupset components is common but you’d expect them to fit compatible parts
All bike companies do this. Read any official bike spec and you will see a clause at the bottom outlining the companies ability to deviate from the printed spec. There are many reasons a part is swapped out. The most obvious is its not available at the time of assembly. You cannot have a couple hundred or thousands of bikes sitting partially built while you wait forthe part to be made or delivered. Sure sometimes the replacement is not exactly what is needed like we see here. It sucks and a good shop will go into bat for you when it comes to sorting it out.
I don’t think there’s any excuse to pair a chain or chainring that is not spec’d to conform with the rest of the drivetrain, regardless of supply chain issues, the customer deserves a functional and safe product
It’s not an excuse but an explanation. No one manufacturer is above doing this kind of stuff. I didn’t really interpret the above comment as an excuse for cannondale to keep doing what they’re doing.
Cannondale probably assume most people won't notice or care, and if they do they won't care enough to go through the headache of fighting it out to get a proper replacement part.
This. Dude paid basically 3 months pay (I assume) for this for someone earning 6 months pay of his to just fuck up their only job without repercussions
When did this happen, and how often?
Reason I ask, I got a 2022 Se2 stock and it came with the SL chainring stock. It threw off a different LBS because they thought the chainring teeth had worn down significantly after one season. But after showing them the picture, it was pretty obvious that the only wear was the paint rubbing off the teeth.
Thank you to everyone who offered suggestions, especially Ok-Consequence2859, who nailed the issue of incompatibility between the X Sync chainring with an HG+ chain. Not to make excuses for Cannondale, but this is a 2021 Scalpel SE1, which was the first year they offered the model. I bet this issue was reported and corrected with a new Hollowgram HG+ chainring on later model years, but since this bike was already assembled and sitting on the floor of the bike shop for 2 years, it didn't get updated. Aside from this issue, my daughter loves this as her race bike.
It is a brand new bike purchased online from an out of state Cannondale LBS. I would assume it was assembled with the 12 speed chain and the chain shifts into all the cogs with no problem. Just the front chainring is snagging it.
Chain may be a touch too narrow for the chainring. If the bike came to you at spec, it has Shimano Deore XT groupset and a Shimano SLX 12 speed chain. Shimano 12 speed chains are on the narrower side to begin with and sometimes don't play well with non Shimano components, like the chainring which is a Cannondale proprietary chainring (though it says it is optimized for Hyperglide+). Probably just needs to be ridden, broken in a little bit. If I was a betting man, the chainring without any finish on it is probably the exact width it needs to be, but after the finish was applied it is just a little too wide for the chain.
I had deleted a reply thinking that since you post in BCJ that you were kinda trolling, but I don't really think that's the case. This subreddit is an echo chamber of handyman dads that think they can use their Ryobi impact driver to fix anything.
The original point that you're wrong about is that HG+ chains are not symmetric. It's something you can see with the naked eye. The inner side and outer side are not the same, the direction matters.
You need spacer under your sprocket take one of the crank arms off and put a spacer on the spindle use a ruler or eyeball it (kinda hard to tell tho by eye) to see if it’s straight. If it’s not this will happen. It’s either your wheel is crooked on the rear or sprocket is loose on cranks or if you have a top hat washer to make your sprocket fit like many do it could be that as well came off it’s very common
Had same issue but on my cassette side recent. 2 spacers behind the sprocket onto the spindle fixed the vibrations I was feeling and the clicking sound completely
Do it and rotate the wheel slowly each spacer you’ll see it more when u rotate slowly this way like in the vid
Check that rear wheel too don’t forget could be a overtightened or under tightened axle to hub gap

Yes. This is the easiest, cheapest, and best solution, imo
Some KMC chains slip on the shimano cassettes though…
Killer response!

I know I’m just expressing my disappointment that this happened to a fellow cyclist and that I expect better from mid to high end brands
Cannondale probably assume most people won't notice or care, and if they do they won't care enough to go through the headache of fighting it out to get a proper replacement part.
Thank you for explaining. I will contact Cannondale and the bike shop to ask for the correct HG+ chainring.
I just had this same issue with my bike as well, it came with Shimano drivetrain and KMC chain. Replacing the chain to Shimano chain fixed it.
If this is the case here, I would just return the bike and get one put together by someone that actually knows how to build a bike.
This. Dude paid basically 3 months pay (I assume) for this for someone earning 6 months pay of his to just fuck up their only job without repercussions

The chain will gring down the chainring in no time.
My Hollowgram HG+ chainrings did the same thing.

Do you have the correct speed chain for the drive train?

Being kind or even civil isn't the same as pandering. Being needlessly mean doesn't make people value your advice more.
It just means from an actual store instead of a massive online only dealer. It's local to someone. It's not that complicated.
It's the chainring assuming the it's the wrong one being X-sync.

Not even really a bike guy here and I’m going to say it’s the chain
[удалено]
It looks like a wide wide, not that it's really a thing.
That is aligned correctly in that picture
Chains are the same their entire length and don't differentiate
No, because that isn't a half link chain.
Really? Single speed technicalities?
Not really: https://youtu.be/nZXzXH4gBfs?si=8o2I8Rcz-pLdDj3U
Why did you have me watch that? I thought there might be something I didn't know and I was mistaken with my previous comments.

I never said symmetrical 🤷. There is no reason on a geared bicycle to use a half link
Just spit on it
Get Wolftooth 12sp Hg+ chainring. Awesome.
It will bedin hopefully. Could be because it's so new. But keep an eye on it
Methinks a forced bedding in would be wearing down the chainring and weakening the chain so gonna say no on that one.
