• Having a little panic that my spokes might be to long, spoke calc stated 289.3, but chosen spokes were only available in 288 or 290. Are the 290 ones going to be to long? Mavic xm319 rim if that makes a difference.
    Quite a few posts in this thread say about rounding down but I've gone up 0.7mm.

    Any help greatly appreciated.

  • Prob too late now, but if you add a Sapim HM washer under each nipple, you add 0.7mm to the required spoke length, in which case 290 would be bang on.

  • It's not to late, still waiting for the rim to arrive, thanks for the info. Would 0.7mm difference really need to be taken up? Or would it not be an issue? First build so still trying to get my head round everything
