Simple question for once!

Which is more functional (if either)?
Which is more "classic" (as done in the past)?
Which is preferable?
Which would you rather see wrapped in twine and shellacked?

Berthoud fenders, VO leather flap.

Thanks.

I put it outside the fender.  If anything drips down the inner surface of the fender, then it won't soak into the (leather) mudflap and can just drain right out.

I put them on the outside so they hang in a mostly flat configuration. If you mount them inside, you force the mudflap to conform to the tight curve of the fender.

It's a wash. Outside mounting allows a wider flap, theoretically
stopping more of the splash when hitting puddles.
Inside mounting follows the tire radius, reducing the trajectory of a
splash.

Leather flaps look more "classic", but supposedly weren't used much in
the past. More typical were thinner, rubber mudflaps, mounted inside
the fender from what I have seen and read.

For a thick, leather mudflap such as the VO; I think you'll be better
off mounting it on the outside of the fender. The thick, leather
ridge would accumulate debris and would also lessen tire/fender
clearance when mounted inside the fender.

There was an article in an old issue of Bicycle Quarterly about
mounting leather flaps inside the fender. This is for folks using
aluminum fenders. You can check their back issue index for finding the
article. But with a VO flap or Riv Sackville flap it needs to go
outside. I have the VO flaps on my commuter, they're great. I like the
looks of the Sackville more and they're lighter and have the
reflective strip on them.

I use inside mounting. Am I the only one? I zip-tie the leather flap
to an appropriately sized piece of plastic (credit card works great)
and "snap" the plastic bit inside the metal fender between the rolled
edges. Secure, quick release, no fender modification needed. Zip tie
is just for insurance. Friction usually holds it between the plastic
card and the fender just fine.

Ryan

Just piling on to concur with what's been said. Generally, I think the
thick leather needs to be mounted outside for clearance reasons (in
most applications.) Looks fine, and works great. If you've got plenty
of clearance, inside mounting would be fine, too.

Thin rubber mounted inside seems to be more classic/traditional. It
does look good, too.

my mudflaps are repurposed quart milk jugs :-) I mount them inside.
If they were, say, leather, I'd mount them outside.

Nice lunchbox with reflector mount there, Alex!

I mount my mud flaps on the inside, it curves the flap and helps it
stay in place rather than deflecting in the wind. Some planet bike
flaps fit over the end of the fender (both inside and outside?).
