BB386EVO crankset compatible with CK ThreadFit 30 BB?

I have a frame with a 68mm BSA BB shell. I ordered an FSA Adventure crankset with a BB386EVO spindle designation.

Is the Chris King ThreadFit30 BB compatible with the crankset? As far as I can tell, the 30mm spindle diameter Is the same, but I can't find a width designation for the CK BB and there is no conversion kit.

has anyone installed a similar combination?

Why spend $200USD on a BB...when the FSA BB386 BB is available in BSA for $50USD on Amazon Prime?

I have no clue if the 30mm BB from CK can be shimmed to work or no...I suppose it could perhaps. CK does a (terrible) job telling consumers what their system works with.

Because the overall cost is cheaper if I have to replace the less expensive one every season. I have two cross bikes - one with about 5000 miles that is on the fourth or fifth set of 6806 bottom bracket bearings - I have lost count. The other has about 12,000 miles and is on the original CK BB. I have not done a thing to the BB other than hose or brush it off when it gets dirty. I have put well over $200 into the "inexpensive" BB, and the CK is only $150 for me.

I trust CK, they are made in the USA, I am from Portland, this is a "dream build", I can afford it, and I don't have to listen to your opinion about by BB when I am riding.

My post was looking for facts, not opinions.

Thanks. I have been there before; they have a pretty impressive operation. Not exactly close to where I live, but I will call them tomorrow.

LOL. Obviously.

I could point out you're not the only one to use thopse bearings...I could point out that you're not the only one who builds dream bikes...and I could point out I have that exact bearing in my Di2 gravel bike and it is has 4,900 miles on it as of this weekend...But obviously you're in a snit and want to spend money. So have a nice day.

So we all have our own unique values, and different opinions on reliability and what components that we would spend money on. I wouldn't put Di2 on a gravel bike (and especially not a 'cross bike) due to the cost, but it is good to know that it works for you and that the technology has evolved to the point that it is so trustworthy. My bikes are steel, have steel forks, wheels made of metal, and no batteries outside of GPS. I don't spend money on carbon rims, electronic shifting, ceramic bearings, or top-end groupsets, but I will spend money on things that are difficult to manufacture like headsets, hubs, and BBs (think: Phil, CK, White Industries). An expensive bike (to me) is anything North of $4k. $10k for a bike is crazy talk.

My initial response crossed the line, and for that, I apologize. I appreciate you taking the time to respond.

Just to provide the answer, I contacted Chris King and they said no. The spindle is just a little too short to make this work. I have the same crankset and had to end up using the FSA BB. I had one from Real World Cycling and the spindle was too short so it confirms what the Chris King rep said.

Agree. I took a ck bb off of another bike and used the FSA crank and it wouldn’t get close to recommended torque before binding the bearings.

It it is a shame. I have all the tools for the CK already. So I had to buy a special tool for the FSA BB along with the brackets themselves.

aggiegrads, do you know if your crank was the FSA SL-K modular crankset? The modular system is claiming to help fit a wide variety of bb frames.

No, mine was the Energy (aluminum, not Carbon). The dimensions should be the same however.

I do not dispute the claims that they can be used on a wide variety of frames, My only complaint is that you have to use the crank with their BB due to the length of the spindle, which makes it effectively proprietary.

Given your good experience with CK's bottom brackets, is there another suitable crank that would work with it? Might be cheaper to change the crank than to replace bottom brackets that frequently.

I put a White Industries crank on my 30mm CK BB, but certainly not as a money-saving decision.

I am happy enough with the Shimano crank offerings in 24mm, I would use their cranks unless they didn't offer the gearing I wanted. There is a gap where the smallest inner ring goes from 34 (road compact) to 28 (Mtn double) and the smallest outer foes from 46 (Cyclocross) to 38 (Mtn), where my ideal would be something like a 30 inner-42 outer. This was what led me to White Industries, which allows just about any gearing combo on a double.
