BB - Chris King or HSC
Moderator: robbosmans
I'm building a new bike which has a BB86 frame. What do you guys think between:
Chris King Press Fit 24 - Steel (c. $140)
Chris King Press Fit 24 - Ceramic (c. $210)
HSC Ceramic BB86 ($135 - http://www.hscceramics.com.au/HSC-Bike- ... -BB86.html" onclick="window.open(this.href);return false;)
The HSC seems to have good specs from what I can tell, and it's also 30g lighter than the CK ceramics. The CK reputation is indisputable though. Help .
Thanks!

Never used BB86, but I can speak/write about HSC bearings and they are fantastic. I've used them on both BB30 and BSA/external cup frames.

im no expert but I can tell you i had a bad experience with a HSC GXP bottom bracket a few years ago, from memory the tolerances were out and they kept coming loose, I returned them and got my money back
was told by my lbs they are just chinese made bearings imported by an aussie company and to try these American made bearings http://www.vcrcbike.com/ havnt had a problem since
prendrefeu has had great experiences so maybe I was unlucky and got a dud set

I'd also recommend VCRC. I have a set (GXP, ceramic) and they are very smooth.
If I weren't running an FSA K-Force SRM which has a slightly larger diameter spindle than Shimano forcing us to use FSA parts, I would be using a KCNC Press-In BB86 Bottom Bracket.

I have a CK 68mm along with the grease injection tool. Just based off of feel, I thought the bearings were nothing compared to the Campy SR I had on my bike before. I only made the switch because I was installing a Quarq. Every time I used the tool it would force the gaskets to pop out, and in general I just felt the CK "name" was hype.
I've since had a Quarq warranty replacement, and now since I am using the Elsa I have a SRAM GXP bb... I'd be interested switching to VCRC or HSC is truly an upgrade.

The VCRC ceramic GXP is an upgrade from the Sram steel bearing GXP but the Sram one is so good that it's only a small difference in the "spin the cranks" test.
I realize that test is not representative of actual use but its what I have available.

Thanks. I understand the "spin" test is not very scientific, but what else do we have? I know when I gave the Campy setup a whirl it was remarkable. The Chris King... bleh! It seems I spent a lot of time trying to tighten the crank "just enough" to avoid play but get some freedom in its rotation. In that sense, the GXP is a nice switch. Just tighten and go. No fiddling.

I think the GXP is the best design for external bearing cranks. Less tools, no preload problems, self extracting, etc.
For certain parts stiffer is more important than lighter.
