Here is a customer review of the first pair laced to tubular rims....
Having said that, the wheelset is awesome. Michael was asked to put together wheels geared for climbing, but all around good ride. I live in Southern California, ride/train on an Eddy Merckx Team SC about 175 miles a week, and do a monthly TT on another bike. Michael's wheels come after a set of Campy Neutrons which I have had on the bike since new. I have been riding with Conti Force/Attack tires. I weigh about 140 pounds.
Firstly, the wheels are extraordinarily light (1220 g), with the entire assembly- rims (Araya), spokes, hubs (DT Swiss), skewers (Zipp), tires (Schwalbe Stelvio tubular), and cassette (Superfine 7075 aluminum- 12/25 10 speed + Wipperman chain) is only 1950 g. My bike lost about a pound and a half in the process of changing to this wheelset. The wheels are not aero, but, at least according to Michael, this is not a factor under typical conditions. On the other hand, stability in fast canyon descents with gusty winds is excellent.
The effect is stunning from the moment the bike is mounted. The reduction of inertia is extraordinary even when rolling off to start, and acceleration, stiffness, and responsiveness are fabulous, from a start and while underway. Almost needless to say, climbing is a joy, taking 30 to 60 seconds off a twice weekly 5 mile/ 1000 foot climb, not to mention the improvement in another 7.5 mile 2500 foot climb.
Meanwhile, descents are remarkably stable and control is excellent- not quite as sure footed as the Conti's- but the tradeoff is well worth it.
The aluminum cassette is a bit of an unknown, but so far with about 1000 miles on it it shows no undue wear.
This is a "sneaky fast" wheelset as its creator would say, and they should be a great asset in future road races. The price was a fraction of a set of comparably light wheels, so the value is also extraordinary.
These wheels are highly recommended.
