I think that stay retention system should allow for pulling out?
It looks very similar to the VO system. On VO fenders, the stays are just held in at the tips by something akin to an interference fit (the P clamp does tighten, but its closed diameter is about the same as the diameter of the stay). I'd like to think they could release in an emergency, but I don't know whether they actually would let go if something wedged in between the fender and wheel: if something hit the stays and the clamps started to rotate, they would probably grab the stays because they would no longer be aligned along the shaft of the stay. I just ride mine, enjoy how solid they are, admire how pretty they are, and try not to run over a bunch of sticks.
I just inherited Cyndi's. I like when she upgrades stuff. I wish she were bigger.
Speaking of upgrades meet the recently overhauled Viaje Classique as I have renamed her. Figured after 25,843.5 miles it was time. Converted to SRAM Force 1 -- 38 front chainring 11x42 rear cassette and brakes from the aforementioned Spyres to hydro. Bring on the gravel!
