I have the clincher version. I haven't ridden on tubulars since 1974 when they were still called "sew-ups"

The brake track is slightly textured. It makes a weird "spin-down" sound when you apply the brakes. It is wearing down a bit after about 400 miles, and now it's getting a bit squeeky.

I let the bike shop set up the brake pads. I'll have to check the toe-in.
