    What Am I Missing: DUB Force 1X Crankset Install, How many Spacers??

    So I've got a new SRAM Force Crankset with the DUB spindle, 68mm BSA.
    According to their chart I should use the 3mm spacer on the Drive Side(DS).
    They don't say anything about a 1X versus 2X setup.

    Local shop owner mentioned using the largest spacer 4.5mm

    I just hate this guessing game, and trial and error.

    If anybody could tell me how they set up a BSA 68mm shell with a 1X road crankset, I'd appreciate it.

    As far as the "DUB™ Road Cranksets and Bottom Brackets" document says, a DUB crank on a 68mm BSA frame requires a 3mm spacer on the right side. It doesn't specify 2x or 1x, so that implies that it's the same regardless.

    Yeah the 4.5mm didn't work. Tried the 3mm. I think I tried both. But even going by SRAM's guide I still find the crank there to be some friction, and a clickety sound that seems to be on the NDS. Played around with the gadget that's supposed to shore up play.
    But I didn't realyy have any play to begin with. Went a little low on torque considering what SRAM suggest at 54 Newton Meters.
    Hopefully it just needs some bedding in.

    'brifter' is a lame word.

    Why did you go 'low on the torque'? You know more than the SRAM engineers? No drivetrain system needs 'bedding in'. That's for brake pads. If you've got some noise you're doing something wrong. What kind of friction are you talking about with the crank? New-bearings-full-of-grease? Or actual drag? You 'think' you tried both spacers? There are only 2...either you did or you didn't. It's not like there's 87 of them. The bearing preload adjuster isn't a 'gadget'...it's a very simple, effective, and proven way of adjusting bearings. Sounds like you might need to take your bike to a shop w/ experienced, competent mechanics and let them take a look.
