2012 3T Mercurio 40 LTD carbon fiber road bike front wheel

3T jumped into the wheels game with their high end carbon tubular Mercurio wheels in May, then followed with the Accelero’s no-photos-included announcement in June.

Now, 3T has added a 40mm deep wheel option to the Mercurio lineup and Accelero 40 Pro alloy clinchers.

The Mercurio 40 LTD uses the same side-entrance spoke design of the originals and center pull Cane Creek inspired hubs (check this post for closeups and details), which they say results in a very light, easily serviced tubular rim. It also borrows the advanced composites and SwissStop pads to improve wet weather braking performance. Claimed set weight is 1250g, and it’s SRAM/Shimano/Campagnolo freehub compatible. They come with Ti axle skewers. Rim width is 23mm at the brake track.

2012 3T Accelero 40 Pro Road Bike Wheels

The Accelero 40 Pro wheels actually measure in at 37mm deep and 23mm wide at the brake track. The rims are 6000-series alloy with a matte black brushed finish and rounded aero shape. It’s billed as an “everyday aero wheelset” that’s rugged and durable. Claimed weight is 1890g per pair and they come with a steel QR axle.

Pricing added when we get it.


  1. 1,890 grams? Pass. I bet when the price is announced on these i can hand build myself a set hundreds of grams less and with a lot less money invested.

  2. Look nice, and 1890 isnt bad at all for a 37 deep clincher every day wheel. Yes, a mindless weight weenie will take issue with it but no sane, non pro would actually buy into the nonsense that a few hundred grams makes a rider loads slower.

  3. The 3T ACCELERO 40 TEAM WHEELSET is 1683 grams, which is quite lite for an aero wheelset, however I would be interested to know the ride quality. Aero rims can be stiff but some fall into the harsh category particulary if they are to be used as an everyday do it all wheelset.
