Our Philosophy
At Particle, we seek to offer wheels that are safe and performance-worthy. Our focus is to make wheels designed for every rider. We offer 6 different road and gravel wheel series, each with six different rim depths, as well as mixed rim depths.
In order to demonstrate the quality of our wheels and to allow for them to be raced in UCI sanctioned races and events, we have decided to certify all of our Ultralight series wheelsets with the UCI.
Going Beyond UCI Testing
The UCI's standard for wheelsets is for them to be able to withstand 40 joules of force in the form of a vertical impact test. While this is the industry standard, our standard for all wheelsets is a minimum of 90 joules. In fact, our lightest road specific wheelset, the RCX33 Ultralight can survive 120 joules, making it three times stronger than the UCI's standard.
Certified Wheelsets
The wheelsets that have received UCI certification so far are the:
- RCX33 Ultralight
- RCX40 Ultralight
- RCX50 Ultralight
- RCX55 Ultralight
- GCX30 Ultralight
- GCX45 Ultralight
- GCX50 Ultralight
The remaining five Ultralight series wheelsets will receive UCI certification in December. Below are the certificates for all of the wheelsets that have received certification so far.
