Evening all, after damaging my second rim in 6 months I am having these rebuilt onto EX511 rims.
Would anyone know what spokes i need possibly? Hubs appear to be 240s. Replacing front and rear. Thanks in advance

You should be able to put your (new) rims and hubs into the DTSwiss spoke calculator and it will spit out the lengths you need.

I did the same and reused my old spokes, just swapped the rim.

XM481 (as fitted on XM1501 if 30mm internal) and EX511 have the same ERD, and so you don’t need spokes unless you’ve damaged any.

Pretty much all DT alloy mtb wheels use 284mm straight pull comps all round in 27.5 and 304mm in 29″

And as the post above says, all the various rims tend to have the same ERD so swapping them about is pretty painless.

Thanks all for this
