Ceramic Hybrid Bearings
Ceramic hybrid bearings, go get them!
There is much less friction with these bearings. As we all learned in science class in grade school, the less friction generated, the less energy lost as heat. Not only that but they are also much more durable as steel and ceramic are not malleable together. Beyond both those two benefits that are already worth the price difference, starting the bike with the e start will also be less stressful on the starter. It’s a good investment, especially if you’re racing or planning on keeping your bike for along time
