Gates Carbon Drive vs single-speed chain, long term lifespan and maintenance
On single sped vs. 11 speed chains. A SS chain should last a lot longer than a derailleur chain. SS chains will have wider side-plates and therefore larger bearing surfaces. The big difference is that SS chains are run with the chain ring and sprocket aligned. Derailleur chains spend most of their time being run with the chain ring and sprocket offset so the chain has to cope with lateral forces.
