Just discovered that my look 695 bearings has worn out and needs to be changed. So I've stumbled across some brands from the net.

1) LOOK - of course they made them but only in stainless steel. But I can't find any online retailers who carry them. If u guys know where to get it, please give me a clue.
2) C-Bear ceramic bearings - They claim to be the official sponsor for Lotto Belisol team. Anyone tried it? If yes, some feedbacks please.
3) Boca bearings - ceramic too. But again, never heard of this brand.

Perhaps, there are even more choices out there. Please share if u have any experience in changing ZED2 bearings.

I came across c-bear when I was researching camp. crankset and all the great reviews from the roadbike forum http://forums.roadbikereview.com/specia ... 17-10.html, over 20K hit, probably the second most read discussion. I am currently still using my old shimano crankset and is very happy with c-bear http://www.c-bear.com/osbb/shimano-roto ... acket.html. Anyway, joined c-bear facebook and they have a brand new posting just to answer your question http://www.facebook.com/cbearCeramicBottomBracket. Check it out.

Hi,

First of you need to know the exact type of bearing that is used in that crankset. he type is often mentioned as a 4 digit number for metric bearings (which I assume it is) plus someting like 2RS or similar.

After that I could tell you where to find good quality replacement beaings but be aware that removing and mounting bearings takes some tools you probably won't have.
I'd stay away from anything "boutique" as more often than not their prices are "boutique" as well with no real added value to the product.

Boca carries just about any type of bearing but quality on ceramics is often below par. Good quality hybrids can be had from SKF and HSC among a few others but if your crank is using a special standard you may be stuck with what the maunufacturer of that ctank has to offer.

Ciao,

EDIT: Bearing type would be 6810 2RS

Plenty of steel ones about, hybrids are a different matter and not cheap:

CS is reportedly the best available quality.

A bit cheaper (some bearings carry ceramic balls made by Cerbec which are excellent):

LOOK started using NTN steel bearings; 6810 LLB, see attached;

http://www.ntn.ca/bearing_performance.htm

I found these to have avaerage perfromance in regards to bearing seal friction, and below par performance in relation to sealing, water detroyed the drive side within 6 months of occasional use...
From washing with bucket and sponge... no sprayed water...

I then moved to NTN 6810 LLU, and these had beter selas but the drag was very high on such a large dia. bearing... so I removed the inside face seals leaving them open, and left the external shields in place..the bearing seat in the frame acts as a shield when the bearings are in place.... this was better but the drag when new was still high... it did ease after a few hundred kays...

This set lasted about 12 months before one bearing started to run rough... i tossed them and replaced with some Enduro Blue, which is now standard fitment from LOOK..... see attached.... 6810 2RS.
These are if memeory serves also LLB seals (light contact). They certainly exhibit less drag than the NTN, lets hope the seals are effective........
