Hi everyone,
I own a set of SKS P50 Chromoplastic Longboard Fenders. What is the largest commercially available brand of mud flaps that will fit the fenders?
Thanks!

What's wrong with DIY? I use old plastic jugs., or you can Buy 24 by 36" sheets of LDPE plastic .

Planet bike sells a set of longish mudflaps, for about $5 a pair..... included fasteners.

Here in Portland, cut-up WBs are very common. I make mine from 2 layers of graphic film, the stuff that was common in the architectural world for overhead presentations. Tape the edges together and they form a flap that is plenty stiff enough to hold its shape going through all but very deep puddles at speed but flexible enough that you can set the bike down minus front wheel with the flap folded forward with no damage at all.

I do have to find a new source. My several rolls of film, recovered from a dumpster in the office building I worked in 15 years ago is almost gone.

There are several sources for leather and thick rubber flaps. You might try the Rivercity, Potland website. (If no luck on the website, a phone call to them should work. I don't think they make them, but they do make a sweet wooden fender and those flaps are common here, often on nice bikes.)

I used an old yoga mat.

I use the heavy-duty rubber toolbox liner and attach them with heavy-duty 3M double sided tape. The one on my all weather bike has lasted for years.
