Dash and Mercury light weight aero wheels

Last week we got our hands of a set of Dash’s latest wheel build. Dash calls them the Aero Race Wheels. And they were awesome. Super stiff and really great at cornering.

Specs:

Dash  Mira/Monica Hubs (39g/120g)

Sapim CX-Ray Spokes

Mercury M5 Tubular Rims 20/24

Full disclosure, I have not ridden very many deep profile carbon tubulars but these made me want to sell my plasma, bone marrow and hair to get some.  Ive ridden tubular tires for a while now and I can honestly say these wheels out did all of the other tubular wheel sets I’ve ridden. For rims so deep these came in at an unbelievable 1080 grams for the set.

The lightness does come with a small price, the wheels were a bit pulsey when going down hill at high speeds, 30+ mph. I think that comes from the rims being a unbalanced at the valve stem. They were also a bit noisy, the spokes on the drive side have a tendency to rub together where they cross, but Dash says on newer models they have added some plastic compound that eliminates the excess noise.

Overall I think these are a great. If you are looking for 1 all around wheel set this may be it. Deep enough for TT’s and light enough for hill climbs. If you need a set you can get them from us here.

We also gave the wheels to our friend Keith Harper (thats Keith at the head of the pack) to try out. Here is what he thought;

Recently I had the chance to test out a set of Dash ultra light race wheels in a race situation. The wheels gave my machine a new lightness that I’ve never felt even with my high end race wheels. In first getting on the wheels, they were noticeably aero, responsive and buoyant. It took little effort to get them up to speed and once there, they felt solid. Once I added a bit of lube to the spoke crossing on the drive side of the rear wheel, the set had a nice hum with no weird ticks or creeks that often come with light equipment. The wheels cornered great and had a nice torsional stiffness while out of the saddle but I think what sets these wheels apart is their vibration absorbing characteristics. They give a great feeling of connection to the road while still speedily floating across the terrain. This makes for great corning confidence and allows the ridder concentrated on putting power to the peddles without pause for bumps and road disturbance.

Basically I loved these wheels and was at a significant advantage in the race; However, there were a few convenience items in setting up the wheels that tripped me up a bit. Firstly, in changing the freewheels I found that aluminum on the free hub was a bit soft and the cogs would get pressed in and stuck when trying to remove them. It seemed that this could become more problematic through the life of the wheel. My second difficulty was that, on the drive side, there wasn’t quite enough spindle sticking out which put the chain nearly up against my frame while in the 11 sprocket. I put a washer on the spindle to give it more room.

While these wheels weren’t drop dead perfect,  I did love them and shed a small tear when removing them from my bike. If the convenience factors get taken care of, these very well may one day be some the planets most desirable wheels.
