Does anyone know what kind of bearings (steel, ceramic, good, mediocre, not good) come standard on a 2018 SS Evo Disc Dura Ace?

Link: https://www.cannondale.com/en/USA/Bike/ ... =undefined
Listed Bottom Bracket: Cannondale Alloy PressFit30
Crankset: HollowGram Si, BB30a, w/ OPI SpideRing, 52/36

No chance that these came standard with ceramic bearings right?

I ordered these when the originals went bad on my 2016 SS Evo with HollowGram Si:

and they were exactly like the ones I removed - They are not ceramic.

NTN, NSK, SKF sealed steel bearings are the way to go. Ceramic bearings are like hifi cables, ppl want to believe they work, but bearing drag only accounts to around 15% of the total bearing friction.

Doesn't Hambinis Bbs use NTN? Would those be better than Kogels ceramic bbs?

The cannondale OE bearings are usually 6806 or 61806 badged FSA with green or blue seals. They are pretty rubbish.

And what Chiz says is true.

HAMBINI! didn't know u were on here, watched a crap ton of your videos, great stuff. Last one i saw was the one where you listed Look, Time, and Dengfu to have the tightest BB tolerences

Can you link me to something you'd recommend on my BB, would i even benefit changing out the stock (brand new BB Bearings that came from Cdale?) I ride ~100 miles a week, casually.
My cousin recently got Kogel ceramic bearings (yes, i know, ceramic blah blah lol, but he said they were around $120)

I'd just ride the stock bearings until they wear out, I've got some stock ones (white seals?) still in a bike from 2014 with quite a lot of milage in all sorts of weather, no clicks, no creaks, spin smoothly still. My Evo is three years old and also still is on it's stock bearings (blue seals I think), last time I checked them, I was surprised how smooth they were still spinning. One thing to check when you get the bike is if the bearing preload is set correctly, sometimes they build them quickly and some shops dont always double check that. If the wave washer is too compressed, it could shorten the lifespn of the bearings.

The only BB30 / PF30 bearings I had issues with were ceramics, they just died quite quickly. I'd definitely go with Chiz recommandations over any ceramic bearings when it's time to replace.

I would only change the bearings if you have a problem. Don't change them expecting to suddenly go loads faster - it won't happen.

NTN 6806 LLB are very popular, reviews on here are very favourable https://www.hambini.com/ntn-6806-llb-30 ... aring.html

Hope that helps

Thanks you both! i've taken my rear wheel out, held it by its spindle, and spun the wheel. It was very smooth. i dont plan to spend over $100 for ceramic bearings, and will likely upgrade to what hambini recommended if/when my current onces give me an issue. Is it safe to assume that what came stock with cannondale are Steel Bearings?
