  • Carbon rims designed with criss-cross weave for style.
  • Sufficient ride quality due to stiffness, with no detectable flex or brake rub.

  • Basalt fibers in the brake track reduce heat build-up and increase stopping ability.
  • M series rims are the lightest available from Mercury.
  • M5C’s are 23.5m wide, which allows you to ride at a lower PSI for a more comfortable ride.

Reasons NOT to buy:

Expert Reviews

  • Pricey compared to competition.
  • This wheelset isn’t as well known, especially under the ‘aerodynamic’ category, which could prevent people from trusting their purchase.
  • No data showing how the wheelset performs in a wind tunnel against the competition.
  • The increased stopping power has to counterbalance the poor braking quality that is common in many carbon wheels.


The Mercury Wheels M5C Wheelset – Clincher is a good option for cyclists looking to purchase aerodynamic, comfortable, and stylish wheels. The high price point and lack of reviews and data can deter some, but for a competitive cyclist, this could be a good option.
