Basing your purchase off a bottom bracket IE: BB86 vs a T47

[panel]

Has anyone been swayed to go with another manufacturer because they prefer a T47 instead of a BB86?

While on the topic what is better ?

I'm never buying press fit again. Serviceability is a top priority

I prefer BB86 over anything else. Super easy to install at home, and pressfit is my personal indicator that the frame won't be a noodle.

I have a Token thread-together BB86 BB. I think it’s a great combo, easy to install, easy to service.

Was quite cheap and very smooth, even with the lowest tier bearings.

Unfortunately PF was unfairly given a bad rep, in reality there is absolutely nothing wrong with the system.
T47 isn’t a standard and it’s annoying with the internal/external 12/16 mess they’ve created - absolutely no advantage over BSA, but people were kinda forced into it by manufacturers.

BBs are literally the last thing I’m worried about when choosing a frame.

I was a fan of BB86, until I hit a bad frame from Giant.
I was also a fan of T47 with 86.5/85.5mm width, until the 2mm flange slipped and scratched the frame, even using the cup tool from parktool.

Although after brought a retaining tool for T47 cups I haven't yet slipped the flange yet, it's still a trauma.

Now I am a fan of BSA, no matter the spindle diameter it just works.

I was repelled by BB86 even though it is a very good design - the choice of high quality 24 mm axle crankset was pretty much limited to Shimano, but then you could only get pedal-based PM...
With the advent of Cybrei-like cranksets this is no longer an issue and I would choose BB86 if there is an option for that.

When choosing which bike or frame will become my next n+1, the type of BB does not influence the decission at all.

One thing to note: aliexpress sells 165 carbon cranks with 29mm spindles, mostly, not 24mm. All else equal, if you want that, get a T47, because BB86 should not take spindles wider than 24mm.
My own frame is BB86 w a 24mm spindle and 170 carbon cranks. That SKU doesnt exist in 165, so i'm kind of stuck, because i refuse to pay 300 odd $ for an OEM / Chinese carbon crankset. I can do 150, but not 300.
More simply: T47 gives you more crank options.

I have BigRock cranks. 160/165 mm options, 24 mm Ti axle, no issues.

Exactly. I see them at 240 eur without chainrings, that's well above 300$ w rings. How cheap can you get them, and how?

210 USD without discounts, and I've seen them under 180 last autumn...

I have BB86, T47 (internal) and threaded BSA frames. In regards to serviceability and now the availability of 24mm titanium axles, I prefer threaded BSA. It makes all the other BB standards back to being a moot point. You get durability and less weight with ti axles.

Between T47 and BB86, T47 somewhat pisses me off because of the different variations: external cup, internal cup, internal/external cup and even different thread sizes which require additional tools! BB86 is straight forward with a bearing press, but the tool is a bit cumbersome if traveling.

BB type hasn't been much of a deciding factor for me. My main bike is BSA and my gravel bike is T47. I suppose in theory the T47 is supposed to have certain advantages, but none that I've been able to notice in practice. My BSA was lighter and has more room for the BB tool, so honestly I'd prefer it if I had the choice of two equal frames for the same price.

I rode PF30 for 10+ years and never had any issues with it. It's light, bearing replacements were cheap, and it's not that difficult to install after you learn how to do it. Bearings did tend to wear out quickly, but I still wish that it was a common standard today.

Great feedback ! When using the BB86  , are you guys using Loctite green retaining compound ?
