A5C Wheelset

We've always regarded Mercury Wheels as a brand offering value-packed wheels that offered nearly the same wind-cheating abilities as the big players while coming at a much friendlier price point. With its all-new A5C Wheelset, the firm managed to still maintain that easier barrier of entry with aero performance, stability, and durability that's better than most. Designed using computational fluid dynamics and honed in the wind tunnel, the A5's sits at 54.5mm deep, but thanks to its patented Kamm Tail Technology 10 profile, it offers a virtual depth of 67mm, ideal for attacking the bunch and riding off the front.

We're used to seeing Kamm Tail profiles utilized in aero frame tube shapes, and modern aero road rim shapes have certainly gotten blunter leading ages of the years, but this is the first rim we're aware of that uses a true Kamm Tail shape. Working with world-renowned bicycle aerodynamicist Paul Lew, Mercury designs a teardrop-shaped airfoil with a small portion of the tail end removed. At real-world yaw angles, the airflow will still remain attached and act as though the teardrop shape is complete without creating a low-pressure area behind the leading edge which causes turbulence, giving you the aero benefits of a virtual 67mm deep wheel. However, the lower profile helps maintain stability in crosswinds and blustery canyon road descents. This makes the A5 an excellent option as a crit, road race, tri, or TT wheelset with the ability to be ridden daily.

The aero benefits aren't the only thing we are excited about these wheels though and Mercury improved the braking performance by using special aerospace resins that achieve some of the highest temperature ratings in the cycling industry. You can descend with confidence knowing that you and your rims will arrive at the valley floor in one piece. Further build notes worthy of a mention are its use of Sapim CX-Ray bladed spokes for improved durability and aerodynamics and Mercury's Tempest straight pull hub using a 2:1 pattern that increases lateral stiffness and better balances spoke tension without the use of additional material.

  • Innovative carbon road wheels that trick the wind into thinking they're deeper
  • High temp resins improve braking and reduce heat-induced failures
  • 54.5mm deep rims with the aerodynamics of a virtual 67mm, improve stability
  • Straight pull Tempest hubs with 2:1 lacing improve stiffness
  • 19mm internal width works well for modern road rubber
  • Hand-laced, straight-pull spokes boost stiffness and durability
  • Ideal for crits, road race, TT's, tri's, and every day use

Read a review on the A5's and liked the idea of the kamm tail. I read up on the kamm tail and immediately started noticing almost all the sports cars have this design.
Back to bikes... I threw them on my road bike to test out and noticed they roll nicely with the hubs having a cool pewter grey anodized finish. The wheels were stiff when I pressed on the pedals or took a corner at speed.
I had a TT a few weeks ago where I won the Cat 2 category, but also bested my previous best avg. speed by 1mph over 40K.
