I have purchased the Hunt “Aerodynamicist” 52/62 rim brake wheels for my Allez Sprint and raced in them all season. They were exactly what I needed, they rolled great with the ceremicspeed bearings. They definitely didn’t hold me back! I was the talk of my local cycling groups when I nabbed a 3d fastest worldwide descent on Hogpen gap near the end of the season. So, out in the wild these bad boys are definitely aero where it counts. I love the wider internal rim, set them up tubeless and they are super grippy with the schwalbe pro one evolution (I use the 25mm tire, but they inflate to 27.5mm)
