Hello,
In a bit of a quandry...
I have a Yeti 575 with a 73mm BB shell. In order to put on a chain device (which is already on there) I need to put in a spacer to bolt the chain device to.
Currently there are race face DH cranks on there that fit nicely, but I am looking at a new, lighter set, as I'm trying to drop the overall weight of the bike.
So the question is: does anyone know where I can get cranks (any brand) that can handle a 78mm BB shell (i.e. 73mm plus the spacer width)?

I don't know that much about cranks, etc, so any advice/whatever would be appreciated.

Cheers
G

    Doesn't it have ISCG tabs?

    No, it's a 2008 frame, so I guess as it's a bit older it doesn't come with them. Otherwise, I think everything would be ok, but this just makes it a bit awkward....

    Shimano Hollowtech 2 are set up for a 73mm shell with a standard 2.5mm spacer (75.5mm total), what makes you think your spacer will be twice as thick as the norm?
    Currently riding a Whyte T130C, X0 drivetrain, Magura Trail brakes converted to mixed wheel size (homebuilt wheels) with 140mm Fox 34 Rhythm and RP23 suspension. 12.2Kg.

    Thanks. No reason to think, just was working off the top of my head what the spacer width was...couldn't remember what I measured the other day. Either way, it's the first time I've read that a bb will handle a 73mm shell plus a spacer. Now time to choose which one!

    simple. bin your cranks and fit any shimano ones.
