Mercury’s next-generation rim profile drastically improves aerodynamic advantage.  A new, bulging profile actually stabilizes airflow at increasing speeds. The rim's unique, seamless transition from sidewall to brake track knifes the air with less turbulence.  
Better airflow. Less drag.  Greater speed.  
As an added benefit, the rim’s new, rounded profile reduces buffeting in cross winds, resulting in a faster, more stable ride in all conditions. 

Seen in the Faster wind tunnel, our M9's were tested with the SmartStop Professional Cycling Team. They proved to be faster than most wheels on the market today.


Mercury Hubs are machined to perfection using some of the lightest and highest grades of alloys possible. You can expect a smooth ride for thousands of miles due to the quality bearings and use low contact seals ensuring low drag while keeping the elements out. Widening the flanges and oversizing our axles, we have maximized the power transfer with every pedal stroke.

As a standard, we equip each hub set with 6 sealed bearing cartridges. Our hubs is fully serviceable and comes with either Shimano/Sram 10/11spd or Campy cassette body.

This will be one of the most used components you will never have think about.
