Had some sks race blades last year but they fell off and although ok solution I wouldn’t go back as not durable enough.
Sks seem to have a new version out this year as do crud. Anyone use these?

Crud Road Race guards are less durable than SKS race blades. Both are designed for bikes with no/ minimal clearance.
How much clearance do you have for guards?

If you have clearance, are p-clips an option for you?

PDW have lots of mounting options for bikes without eyelets. Available in the UK here.

Portland Design Works mudguards.

They will fit almost any bike and work really well.

PDW FTW

Clarencefield was fine on the race blades just the fixing clips were plastic and quickly failed hence falling off. Only need 25mm tyre clearance for my bike
