John P.wrote a review of HED Ardennes Plus LT Road Wheelset - Clincher on August 17, 2017
Familiarity: I've used it several times
These are stiff, light, fast, super comfortable wheels. There is much written about their width and its effect on tire performance and bike handling--in my experience it's all true. I weigh 145 and run these at 70 psi with 25 mm GP 4000s. At that setup I'm a bit faster than I was at 95 psi on narrower rims, and the ride is definitely gentler. If anything, 70 psi may be a bit too much. The wider tire profile coupled with the wheels' stiffness also boosts cornering grip, a lot. Throw the bike into a curve and you just get solid response and a smooth transition in and out. I haven't found an uncomfortable depth for a turn on these wheels.
I only have about 400 miles on them now, but they've stayed true through several mishaps with crappy pavement, steel plates, bridge seams, etc. The hubs seem to still be breaking in and rolling faster and smoother, but maybe that's just my imagination.
I had no issues with packaging or setting them up. HED's Youtube videos on the wheels are useful, particularly as to appropriate pressure. I haven't tried tubeless tires on them yet. I did have to replace the brake cables (with slightly longer cables) to let the brakes accommodate the wider rims. I also notice a little thump, thump at a certain braking pressure, which I think is diminishing as the braking surface gets broken in.
Tommy at CC was a great help in selecting these.
