I have been looking for ages for a chain lighter than my YBN titanium chain . Problem is the chain's rollers are only titanium . The rest is steel . Any help would be appreciated .

I was also thinking about stripping each link on my chain and making (lots) carbon side plates to replace the outer chain plates .

That sounds like a recipe for broken chains and broken bones.

Unless you have a lab to do extensive chain testing, I wouldn't go into making your own chains. Maybe for a hillclimb event where you don't go fast enough to injure yourself.

The side plates on a modern chain are extremely thin. I don't think it's a place you could just substitute carbon for steel without changing the dimensions. But changing the dimensions would mean it wouldn't work on 10 or 11 speed drivechains.

Hill climbs put extreme forces and tension on the chain. As you jih, plates are thin, even if you could engineer rivets and plates, which would probably be figure 8's out of carbon tow, not just CNC's carbon plate, that were strong enough, it wouldn't match the high strength per volume steel has. The carbon plates are softer than steel and even if they had the right dimensions, would not be nearly wear resistant as steel and would be chewed up by sprocket teeth when shifting. If you still somehow managed to make a working carbon single speed chain, then it's still pretty pointless anyways, because you might as well use a belt drive and custom fabricate a seat stay split instead of chain plates and rivets.

I would be skeptical of using the lightest chain on the market, breaking a chain could be a huge problem.

That's right, I was thinking it'd only have to hold up for a few minutes and be binned though. I wouldn't do it.

A full carbon belt drive with an internal hub gear might work, but you more than lose the weight savings
