i felt like this topic deserved its own thread as some new stuff definitely is worth a look, so i didn't wanna toss it in another thread. yes, there's a lot of crap out there, but every now and then some cool stuff comes up. this caught my attention today: https://bikerumor.com/2019/04/03/ta...ears-making-chains-by-eliminating-the-roller/ they figured out a way to remove the rollers from a chain and integrate that function into the outer plate. there's a thread in the shop forum on chainrings and one of the topics discussed was wear between chains and rings, and the part of the chain that actually wears out. the company making this chain claims the primary benefit will be improved durability / longevity of the chain, but stops short of claiming an actual amount of improvement.
