Particle’s 835g RCX27 Hyperlight is the world’s lightest UCI-approved carbon road wheelset

Specialist brand Particle has unveiled its RCX27 Hyperlight Road carbon wheelset, officially claiming the title of the world's lightest UCI-approved wheels. Weighing a mere 835 grams per pair, these wheels push the boundaries of lightweight componentry. The announcement, highlighted by *road.cc*, also showcased Particle's broader range, which includes several other wheelsets tipping the scales at under one kilogram, firmly establishing their niche in the ultra-light market.

This achievement isn't merely an exercise in gram-shaving; it reflects a continuing trend in professional cycling where marginal gains, particularly in rotating mass, are aggressively pursued. While the UCI's minimum bike weight limit remains 6.8kg, lighter components offer greater flexibility in frame choice or the addition of power meters and aerodynamic accessories without penalty. Particle, as a relatively young brand, is now positioned alongside established players, demonstrating that innovation can still emerge from smaller outfits challenging the status quo.

Ultimately, 835 grams for a wheelset is an impressive feat of engineering. Whether the marginal speed gains outweigh potential durability concerns for the average rider remains to be seen, but for the weight-obsessed, Particle has certainly delivered.
