Have a mystery creaking (more like knocking) when go up the steeper hills.

Everytime i google pf386 ...i just get i fo about bb386 and bb386 evo ...is that what i have ?

Bike is CF kuota khydra ...its still under warranty, but its a good drive back to shop where I brought.

I heard about all the problems with press fit bbs, which is what I presume i have...but would like to know the quality/reputation of the pf386 ?

    PF = press fit.

    my Scott CR has the same BB standard and yeah its a nightmare finding the exact model, my advise get in touch with kuota and ask them what they recommend.

    Rule #5 // Harden The censored Up.
    Rule #9 // If you are out riding in bad weather, it means you are a badass. Period.
    Rule #12 // The correct number of bikes to own is n+1.
    Rule #42 // A bike race shall never be preceded with a swim and/or followed by a run.

    Stick one of these in and you’ll never creak again.

    was is the difference between pf386 & bb386 ?
    Kuota lists the Khydra as having both ?

    As far as I'm aware, PF386 is just another way of describing BB386EVO, that's all. I have a bike with 386, fitted with an Enduro adaptor to take a HT2 chainset - no issues with it at all.

    Thanks thats what I was after.

    From what I have read then BB386EVO isn't a particularly troublesome bottom bracket.

    Took it back to shop - looks like I am another PF victim, Faulty BB - will be upgraded and replaced under warranty.

    My Reacto has a BB386 Evo and creaked from almost day one. As I use Rotor 3D24 cranks, I switched it to a Rotor BBright 4624 and hasn't made a sound since.
    I ride a bike. Doesn't make me green or a tree hugger. I drive a car too.

    I think the BB386 describes the bottom bracket shell in the frame. PF386 describes the actual bottom bracket which is pressed into the aforementioned shell.

    Glad you're sorted.

    @ ITB: the CR1 has a simple BB86 shell, no? Mine came with a bog standard Shimano press-fit BB71 in place, still smooth and silent after 6 years. Possibly because it never goes out in the wet and /or I have the power output of a small child.
