Bottom bracket for BB386EVO crank in a BB86 frame - Any experiences, good or bad?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Bottom bracket for BB386EVO crank in a BB86 frame - Any experiences, good or bad?

I asked this question four months ago and received just one response from someone with actual experience with this. I'm asking again in search of more experiences.

I'm hoping to use a BB386EVO crankset (30mm shank) in a BB86 (41mm O.D.) bottom bracket shell. Wheels, Enduro, FSA, Rotor and others make double-row bottom bracket bearings for this application but there are very, very few reviews of these products online. Reviews of the equivalent bottom brackets for MTB use are uniformly positive (which may or may not be helpful). Does anyone have experience with these BB386EVO-crank-in-a-BB86 shell bottom brackets? What brand? For how many miles? How well do they work? Are they reliable?

Thanks in advance for sharing your experience and recommendations.

My Storck is bb86 and when I first built it up back in ‘17, I stuck with my go-to Praxis crankset and it has the 30mm spindle (tapers to 28mm on the NDS end).
I never had any issues with the bearings slipping out the bb shell and didn’t have any noise related annoyances that can sometimes happen with press-fit bb shells.

About a month ago, I upgraded to a Quarq Dzero crankset which also utilizes a 30mm spindle. I went with Hope 4130 bearings and these feel even smoother than the Praxis bearings I had prior.

Are these double-row bottom brackets different in feel or performance from a traditional single-row BB? How many miles would you say you have on them?

Thanks for the reply. There are so few with experience with this setup . . . I guess I'm not eager to be an early adopter on this. I will stick with a BB86 and a conventional compact crankset. I suspect Shimano will come out with a sub-compact before too long -- won't they?

Depends on what you mean by "too long"...many people have been waiting for a 1X crank from them longer than people have been waiting for a sub-compact. They're still waiting.

AAMOF...none of the Big 3 make sub-compact doubles. Given that new XTR was just unveiled last year alond with new Ultegra/DA...it is probably going to be another 3+ years...Unless Shimano pisses everyone off like last year where they unveiled Ultegra, and then 4 months later released a clutched-Ultegra RD.


There is a ton of cynicism toward FSA products to start with...being regarded as a budget brand and all....and 386EVO just as much, although many people tend to abused the heck out of BBs--and spindle BBs like that far less than cartridge sq taper units. My SL-K 46/30 is still running fine in its threaded 386EVO cups after 6,000+ miles....something you wouldn't expect from the trash talk on the internet towards 386EVO online.

Point taken. But I'm one of those guys who thinks 1x only became a "thing" because SRAM never figured out how to make an adequate front derailleur / shift package. SRAM gave up. Shimano actually has a functioning front derailleur, so they haven't seen the need to make a road 1x.

Running a ROTOR 4130 on two different bikes with 2inPower Cranksets. Probably 1,500ish miles on each. Still spinning great. Creak free.

I don't think the double row has anything to do with performance. They have to use two rows of bearings because the 30mm spindle and 41mm shell require the use of pretty small bearings. The double row is to spread the load out.

As glfguy8 said, the double row of bearings is to help alleviate with load. With the current Hope 4130, I'm closing in now on 1K miles. Creak free and still spins nice and smooth.
