    I'm going to buy a Spark frame with a press fit BB & want recommendations for a creak free experience
    Any suggestions?

    Hope Ceramic PF92 - fit and forget.

    Usually it's not the bearings that creak but the BB cups sliding around in the BB shell. Loctite or tubular tire cement keeps it in place. I've never tried the tubular cement, it was a recommendation from an engineer at VCRC Bike who's big into cross.

    I praxis is supposed to make very solid pressift BB's as well.

    I would recommend VCRC but they don't recommend their BB's for mtb since you need to keep them clean to get the benefit from them and the dirtier conditions means you need to do that more. I have them on my mtb and CX bikes anyway, despite what they've recommended to test that theory out but don't have a ton of time on them on the off-road bikes.

    If shimano has a BB in that standard, they also make a solid product. Sram is hit or miss if you need a sram BB, I'm just not a fan of how hard they are to get back out so I avoid them now.

    If I were looking for a creak free bottom bracket I'd try out the new ones from Enduro. Enduro launches TorqTite press-fit bottom brackets - BikeRadar

    I have yet to have ANY Scott frames creak from the PF BB, they use the PF92, most bikes that have the non stop creaking are a PF30 application.

    Ideal, do you use any Loctite or similar products on the BB/cup interface when fitting the BB to the frame?
