Looking for fenders/mudguard and rear carrier for a Synapse néo 2

[Yayabike]

Hi there i m the very happy owner of a cannondale synapse néo 2, it has all the plug and hole to add a reard carrier and mudguard.

For the carrier i would prefer a light one with only the frame to attach paniers, so ineed a kind of "tube" model.

for the mudguard i would rather go for sturdy dark platic (the bike frame is black).

So any advice is welcome.

Side note I would rather not spend 300 euros for the fender/rear carrier combo.
