    Bontrager crankset BB cups....

    I see a lot of Bontrager cranksets for sale on eBay and elsewhere.
    Almost none have the BB cups to go on the BB shell.

    I bought one crankset, and it came with them.
    I bought another, Race Light triple, and it did not.

    Are these cups available, or am I SOL? (Shoot, Outa Luck)

    Thanks.

    I think bontrager uses GXP, which means you need a truvativ/SRAM BB.
    I'm not 100% sure.
    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    Treks may suck hard, but that is a regular GXP bottom bracket, as has been said.

    Thanks for the advice.

    Bontager may be trash to some, but when you're trying to build a friend's daughter a bike for Christmas, you do what you can.

    I didn't realize I was so close to the Road Forum.

    just remember to use both spacers when installing on a 68mm BB shell.

    no, I'm quite correct.

    68mm BB shell required both BB spacers on the GXP to be used with a truvativ triple. Otherwise the taller stepped portion of the axle won't rest on the BB properly, would leave a bad chainline and a rather large gap between the crank and BB on the drive side.
