    I’m building up my first ever wheelset which I’m looking forward to.
    Spoke lengths has me being a bit cautious though.

    Specs on the wheels:
    – Hope Pro 4 Boost 110 front
    – Hope Pro 5 Boost 148 rear
    – DT Swiss U 663 20″ rims

    DT Swiss spits this calculation out for me, but it doesn’t look quite right..

    Surely what I want is: 32x 183mm & 32x 184mm ?
    – Spokes; think I’ll go for double butted 2.0/1.8 spokes
    – Nipples: Some DT Swiss brass 14mm nipples

    Would welcome any thoughts and advice!
    Cheers all.

    What spokes did you select on the DT tool? I think it can give (slightly) different numbers for different spokes. Also make sure you have selected the correct nipple.

    If there’s only 1mm between the spoke lengths I’d probably just round up and get them all at the longer length.

    I usually plug the numbers into a few different online calculators as well, as they do vary a bit.

    Yup, good point- spokes were the Competition 2.0/1.8 & nipples brass 14mm.

    Thanks all! Ordered 182mm & 184mm.

    Looking forward to building these up ?

    Spokes stretch a mil or so when built so it’s not entirely unreasonable to round down a bit as per the calculator above.
