Ceramic vs Steel Bearings: Truth, Myth and the 10PLUS Premium
Ceramic bearings are real engineering, but the marketing around them often runs ahead of the evidence.
The truth
Ceramic bearings can offer low friction and a smooth feel. That doesn't mean a ceramic wheelset makes you several watts faster in every real-world situation.
Across a whole bike, tyres, chain, riding position and wind can easily outweigh the small contribution from the bearings.
What 10PLUS changes
Both tiers use S&S-branded bearings, according to 10PLUS's own spec: steel cartridges on the T Series, ceramic on the E Series. The E Series adds a 45T ratchet and a lighter build to its ceramic bearings; the T Series pairs its steel bearings with 36T engagement.
So the sensible comparison is T versus E as complete wheelsets, not steel versus ceramic bearings in isolation.
The marketing myth
Be wary of claims that ceramic bearings “add power”. Bearings reduce losses; they don't create watts. And a freehub that feels faster isn't the same as more power at the pedals.
The E Series can still be worth buying. The point is to know what you're paying for.
The buying rule
For the best value, the T Series. For the lighter premium package — if you're happy to pay for it — the E Series. That's the honest 10PLUS bearing story.
