Appologies for the dull subject but any advice is welcome

Building up another cannondale EVO for this season but unsure which pf30 to go for.

SRAM - PF30 - cheap - never had any problems
Wheelmfg - alu shell with enduro angled bearings
Chris king PF 30 - expensive? 5 times cost of SRAM

From what I read the durability of ceramic bearings seems a problem, so I'm happy to stick with steel

What's your experiences good / bad

Thanks

I had heard several users with SRAM that had no problems with creaking or slippage, but with durability. Then I was introduced to the version that pushed in but had threads that a standard Shimano or other bottom bracket just threads into -- nice, but it just rotated when I tried to tighten one side so I needed two wrenches, and I had a problem with it loosening up. Others have endorsed this system.

I looked at a number of PF30 designs like the Praxis, but they each had their own particular issues -- the Praxis, for example, didn't have clearance for Di2 cables in a Moots frame (and Praxis warns you about it on their website). And on and on.

I finally went with the Chris King PF30 and have it in both carbon and ti frames without a hitch. It installs smoothly, lasts forever, you can get ceramic or steel bearings, it has colors, and it works easily with Di2 and other systems. Most importantly, no creaking. Right now I think people are picking PF30 bottom brackets based more on personal success than anything -- and everyone has differing experiences. Mine says to buy King. A couple shops I admire tremendously have the same praise for the SRAM, as do a couple frame builders I know. The King is newer to market so fewer people have used it, and there are other systems that have frankly been around enough to collect enough rants to turn people against them when it isn't really warranted. Installation is really the key on all of them. Heck, it's a bike (and it isn't a 9000 front shifter). I don't think you'll really go wrong with any of them.

Whats wrong with the Cannondale KP197 SRM PressFit PF30 Bottom Bracket - PF30, alloy cups, replaceable steel bearings?

I like the Wheelmfg BB. Seems like a smart solution.
