    Wreckoning bottom bracket and crankset

    Googled like a maniac but still can't work out without a doubt which BB I should be looking for that will fit a Wreckoning frame. Spec says "threaded 73mm BSA BB shell" but which BBs match this?

    Also, which cranks will fit the BB I chose above? And do I need Boost cranks?

    What are you guys using? All suggestions welcome. Thanks.

    Name the cranks you want to use (Shimano, Sram X whatever, Raceface Next SL, etc...). From that information we can offer up what bb to purchase...

    Thanks for the reply. I'm not set on any particular cranks atm still undecided, but looking at mostly SRAM X01 carbon or cheap Gx, Raceface Turbine or Next SL. Would be interested in hearing what you guys have on yours.

    I went with a *raceface turbine-x-type-68-73mm-bottom-bracket. Very happy with it so far.

    How about Shimano's XT BB called BB-MT800 Bottom Bracket BSA Hollowtech II. Would that work? Thinking about a full XT groupset and it comes with that BB.

    Figured this is a good place to ask this. What 30mm BB are folks having success with for RF cinch cranks? I'm done with the RF BB as they dont seem to hold up in the PNW and begin creaking.

    As said earlier, choose your crankset first...this will determine what BB you need. At the moment you are doing it wrong way about...letting your choice of BB decide what crankset to use. The Shimano BB you mention above will enable you to use any of the Shimano Hollowtech II cransets such as XT or SLX etc... I would recommend using the XT "Boost" crankset to help with chain alignment. The Wreckoning is a 73 mm wide BB shell, so you will need to use one 2 mm spacer on the drive side (spacers will come with the BB).

    Gents, can someone explain if bb30 cranks will work with the wreckoning? I bought a wreckoning second hand, it came with the raceface 30mm bottom bracket, obviously the frame is 73mm bsa. Can I run sram bb30 cranks with this setup without problems?

    I have a set of xx1 narrow 156q gxp cranks. I installed a gxp bottom bracket and the cranks but there is not enough clearance. I even tried it with two 2.5mm spacers on both drive and non-drive sides. I know even if I have the clearance this would probably result in issues from insufficient engagement.

    Anyway I'm looking for the best/least expensive crank option to add to the components I already have. Thanks.
