Particle carbon wheelset - 1100g for 60mm !!

The reviewer provides a detailed, hands-on review of the Particle RCX60 Ultralight Carbon Spoke Disc Brake Road Wheels. They cover unboxing, specifications, build quality, and on-road performance. The wheels are the 'Ultralight' flagship model, featuring 60mm deep, glossy carbon rims with a 21mm internal/31mm external width, a hooked design for tubeless/tubed use, and a claimed weight of 1100g (500g front, 600g rear). The hubs are the top-tier SR1 model with ceramic bearings and a 36-tooth ratchet. The reviewer praises the weight, transparency of the manufacturer, availability of spare parts, good aerodynamics for flats, excellent climbing ability for their depth, and easy tire fitting. Concerns are raised about lateral flex under sprinting for heavier riders, the cheap-feeling rim tape, and the effect of crosswinds (typical for 60mm wheels). The reviewer concludes they are suitable for light to medium riders but may be too flexy for those over 85-90kg.
