Particle

Es el segundo juego de ruedas que me compro y creo que con eso lo digo todo. El primero fueron las RCX UltraLight para la bicicleta de carretera y ahora estas para la bicicleta de gravel.
La rigidez de la llanta es máxima y a la vez la absorción de los baches también, en la bici de gravel esto es muy importante.
Sin lugar a duda volvería a comprarme otras.

Ruedas superligeras y fantasticas como ruedan , y muchas gracias a Patrick siempre muy atento , y te saca de dudas enseguida , nada que envidiar a una rueda de super gama alta de 3000 euros .

FANTASTIC WHEELS!! Wheels give you watts.

The wheels respond amazingly downhill being rígids and reactives on the accelerations.
The lightness is great leaving my trek madone in just 6.7kg!!!

Great customer service and support during the order and delivery process.
Precise manufacturing prooved when installing with my new Winspace Agile, Sram Force E1 groupset and GP 5000 700 x 30mm clincher tyres managed to put on easily without any levers , pumped to 32 mm keeping 105% ratio. I am happy with my choice is only 100g heavier than ultralight but the combination of rim stifness and 4 gen carbon spokes provide uniqe riding feel (stiff when acccelerating or climbing and comfortable on rough tarmac), The cross wind has almost no impact nor when trucks passing, I feel aero effect , also with head wind and they sound great, my average speed has increased significantly. I tried them also on my other bike gravel Trek Checkmate, woul like to have another pair of GCX!

très bonnes roues

Great, light, fast, perfect combination with the new Gen 8 Madone SLR7 AXS

Update 26.06:
I have finally been able to set up and ride my new wheels and I can only confirm my 5* review. I think they look amazing on my TCR, with the 52mm depth and understated elegant finish matching the frame perfectly. Came in at ~1028g with tape, which is pretty much spot on the claimed weight. Not only that, I really put them through their paces by using them for the Sportful Dolomiti Race last weekend, one of the hardest Granfondos in Europe with 5000m of climbing (and thus also descending). Felt really snappy on the climbs and nice and stiff on the descent, paired with 30mm Pirelli PZero they gave me loads of confidence and the transition between wheel and rim was spot on.
I had no problem setting them up tubeless with the provided valve and tape and they held air just fine. Putting the tire on was a bit of a struggle, but that was the same on my previous rims as well with the Pirelli.
I will definitely be looking at Particle again for any future upgrade or ne bike build!

Original review 23.05: Very pleased and excited by my new GCX Hyperlights. The specs are amazing and the feeling in the hands is great. I have just mounted them and will take them out for a proper ride soon. I will update the review with pictures and ride impressions as soon as I get the chance.
Ordering and delivery process was smooth, only a little long but understandable given the way from China to Europe and the production time, as these are made to order.

On top of everything, customer support has been outstanding. Patrick was very happy with explaining to me the various differences between specs before my purchase, to make sure I made the best choice. He also was extremely supportive after delivery, when I had some doubts to be clarified (turned out nothing wrong in the end, just my lack of experience with high-end wheels!).
Totally recommended, I will be definitely looking again at Particle for future purchases.

Super rendement très légère très bon roulements très beau moyeux ? Je vous savoir pour quoi sur les jantes côté pédalier c'est marqué GCX 52 roue arrière et roue avant de l autre côté dommage Super content merci bonne journée

Ho finalmente provato le ruote, le trovo veramente ottime, molto leggere, reattive e veloci. Le 50/50 anche se io sono leggero non creano problemi con il vento laterale. Molto belle e ben rifinite esteticamente.
Sono molto soddisfatto.

I am an amateur rider weighing around 55 kg, with a power-to-weight ratio of approximately 4.5 W/kg.
This wheelset is extremely lightweight, and I have no complaints about its stiffness. I use these wheels not only for hill climb races, but also for my regular daily rides.
I ordered the lightweight hubs, and they spin very smoothly. They are also easy to maintain, which is a big plus.
Overall, I am very satisfied with this wheelset. I like it so much that I am already considering purchasing the next model as well.

Very high quality, light at just over 1100gm and excellent hub machining and tolerances, precision is crazy good.

Nice to ride , nice design , improved performance !

Belle expérience avec ces roues très agréables à rouler.

These wheels are fantastic. Lightweight and aerodynamically superior, they deliver top performance in all conditions. The 25mm inner width enhances stability, making them ideal for long-distance riding.
