My bike shop fitted some SKS hybrid (700c not 26") fenders/mudguards to my cadenza 8. They need the longer stays to bend under the front disc brake. The material is polythene, not chromoplastic and I think they are kept under tension to reduce the radius so they a close fit to the slick tyres and provide very complete coverage.
Ill post a pic of the bend in the stainless steel stays that you need.
