What model of Quarq DZero is it? Is it SWorks specific?

sorry i’m not thexhnical enough to answer it properly. but this may help

inwas in my 2018 s works ultra light which had 172.5mm arms and 52/36 ring set.

so if the spider is detachable from
the chain rings and the bolt pattern is similar to s works. then should work.

again i apologize for my non technical response.

Was your crank 130BCD or 110? A way to tell is whether your crank is 53/39 or smaller.

my rings are 52/36

Is this still available?
