cerverlo p3 with full ceramic bearings
Quote | Reply
I have cervelo p3 2016 with rotor 3d cranks and 24mm bottom bracket
Hed Jet Plus front and hed jet plus disc back
I am thinking to upgrade all bearings (wheels and BB) with full ceramic bearings
Anyone know where to buy full ceramic bearings (not ceramicspeed)?
And how to know what exactly bearings i need? And do I need to replace all BB or just bearings?

What do you specifically expect to gain from such upgrade??? Why waste your money? ......the difference is really peanuts but the cost per watt saved is high. Lots of better investments to make before switch all bearings to ceramic - new helmet, top skinsuit, latex tubes, best tyres, aero testing, aero brakes (eg Tri-rig) the list is endless but ceramic bearings are I think at the very end of the list.

I would second the enduro bearings. They are durable, ride very smooth and you can put a lot of miles on them.

What BB are you using? Rotor, Wheels Mfg, Praxis Works, reducers?

Full ceramic or hybrid?

Phil Wood's "carbonyte" steel bearings would be a better choice.

As others say, very small gains for ceramic stuff. Having said that, I wouldn't hesitate to buy this BBright ceramic BB (see link below). Not so much for the ceraimic bearings, but rather the BB is a combination press fit / threaded shell that wil significantly reduce creaking, and BB's walking out of the frame. For ~$55 (with ceramic bearings), it's likely the best value you can find, with a improved cup design over the standard PF BBright bottom brackets.

Switching to full ceramic bearings is insane.

The BB is a PF4624 BBRight. I’m pretty sure the bearings are 2437 size.

I’d suggest a Wheels Mfg BB that threads together in a virgin frame, however you will have retaining compound in now so unless its creaking just swap the bearings.

Would I do it for watt savings? No. I do like the idea of Enduro’s XD-15 bearings for longevity, if you can afford them.

If it was pure watts, an oversize derailleur pulley would be my purchase before bearings.

Reading all the answers and checking links I think Enduro’s XD-15 could be most reasonable choice for performance and longevity

What do You thong about company like this?
https://www.c-bear.com
Even some pro teams are using and price seems reasonable

And oversize derailleur pulley - any alternatives for ceramicspeed? I have
Shimano Ultegra 6870 Di2 11 Speed Rear Derailleur

An interesting product. Have you installed it actually? I am assuming that one side presses into the bb and the other side threads into the plastic shell somehow?

Next races on the schedule: Desert Tri Oly 2018,Oceanside 2018, Santa Rosa full 2018

So I can just buy two if these and swap bearings?

I just replaced my bearings in my Reynolds wheels. I found ceramic bearings with steel casings for ~$7.00 a piece. Total ceramic were ~$23.00 a piece. Normal steel ball bearings were ~$3.00 a piece. I went with normal bearings because the guy told me I wouldn't see much, if any, gain. The biggest advantage going ceramic was they don't need oil or grease but they don't last as long as steel and will need to be replaced a lot more often.

I have the equivalent from wheels mfg (see link below) which is the same concept. One side presses in and the other threads in.

http://wheelsmfg.com/...bottom-brackets.html

The only downside with the cups (I assume it's the same as wheels mfg) is that you need a oversized FSA Mega EVO BB tool. It's a few mm larger than the old shimano hollowtech tool and doesn't seem to be overly common. I had to buy this tool: (https://www.parktool.com/...6%20Bottom%20Bracket)

I stand corrected: The aliexpress threaded BBright uses a smaller BB cup size that looks like it is compatible with standard shimano hollowtech bb's.

Hello

Ar last I took everything apart. And now i know exacly what components i have

Crank is Rotor 3D30 (30mm)
BB is BBright PressFit 4630
Bearings are 4230

Can anyone post from where I should buy bearings (Ceramic) and is it good to replace only bearings? I prefer performance over durability.
BB looks fine not creacking but bearings could run smoother.

I live un Europe so something with shipping from EU could bet better.

Since i could not find 4230 bearings i now look ar

And
https://www.bike24.com/...7C%7C%7C%7C%7C%7C%7C

But the numbers un spec is not the same. Can anyone advise witch BB is right One?
But i still prefer to buy just 4230 bearings. Ceramic.
