I've installed two sets of the VO 700x63 fluted fendersets on bikes running SBHs. It's quite easy, and requires minimal reshaping of the fender. Just lightly pull both edges outboard along the fender radius to get them reshaped down a bit to the radius of the SBH. Great coverage, and I'm nowhere near the tire at any point. Leaves and small sticks still pass though just fine. Unlike what I've witnessed on some Crust frames with 62mm curved Honjo/Simwork or Wavy VO. I like this VO model better than the Honjo/Simworks version because there is an indent in the rear fender that allows the chain and front derailleur to move inboard for low gears without hitting the fender. Like all VO fenders, they come predrilled except for the seatstay junction.
The bikes are an Elephant NFE, and a rim brake precursor NFE.
