Best Sealed-Bearing Alloy Pulleys?
 

I've run the cool-looking superlight Gorilla Billets for a several years. The jockey is extremely worn, so time to replace. What are the best picks?

The Carmichals have served me well for about 2 years. The only issue I've had, is them freezing up after use in mud and water. Last winter, every few months I'd have to clean the bearings repack them with grease.

I got the Performance ones a few yrs ago and the bearings were prepacked at the factory with sand. Much worse than the OEM sleeve bearings, very gritty and rough. Things might be different now, with Chinese sourcing there are few QC benchmarks.
