thanks for the thoughts, dynaryder. They pretty much reflect my own, which is why I posted here. My LBS has a very sparse (like nil) assortment of these kinds of "permanent" fenders. They are more into the clip on style.

I decided to get the PB Cascadias for Hybrids (not the ATBs) and use them on my late 1980s mixte. It has 27" wheels and 1.25" tires (31.75 mm) so the Hybrid fenders with a width of 45 mm should work well - with plenty of clearance for fenders on both tires. One of a number of planned mods. Then I'll have a drop bar bike w. fenders, a rear carrier and panniers which is more practical for my uses.

The Quick4 will remain the pretty streamlined cutie that she is. I do have an SKS clip on for the rear fender and I'll make do w. that.
