    Truvativ AKA head ache

    I have ordered this Truativ AKA chainset from merlin cycles as it seamed a bargain and I was hoping to run a bling ring with it.

    I wanted to put it in my trek superfly which has a press fit (BB91) bottom bracket.

    I have now realised that I ordered a BB30 option (not arrived yet). Would this still fit if I used something like this?

    Nope. The crank is going to have a 30mm spindle.

    No. That's for GXP, not BB30. Haven't seen anything that allows BB30 cranks to fit in BB92 or BB95.

    I'm surprised your Trek uses "BB91". Is that accurate? Not BB95, where they actually insert cartridge bearing directly into the BB, without any nylon cups housing it? BB92 would be the kind of BB that uses nylon cups like that SRAM BB you linked.

    BTW, that first link was amusing. I laughed when it said "Truvativ_head_ache" in the address bar, as it was going through the affiliate click through links.

    Not with that BB, but there are kits that will allow you to use your BB30 cranks in a BB92 shell. This one, for example.
    Spindle length is going to be your concern.

    Thanks for the replies folks. I guess I'll have to send the cranks back, and then get a GXP type crank to use in conjunction with the bb92 bottom bracket and blingring.

    The bottom bracket in the trek is a shimano BB91-42, I think I'm right in saying that it is a BB92 type.

    I measured it today, not enough length on the spindle to do this.

    Thanks for the suggestion though. Cranks now sent back.
