Cascadia MTB 60mm (26") on my new commuter Kinesis Decade Tripster.

They are fitting a little loose to the tire in the back but I might leave them that way. The mud flaps look durable and are firmly attached with (2) stainless steel rivets.

The mounting hardware is top notch (everything is stainless steel) and the stays bend nicely to fit a disc brake if necessary. I had to shim the from fork attachment because my fork has so much room.
