Both my wife and I got C5 Aero framesets back in August of 2025 and after nearly a year and a combined mileage of over 15,000km think they are awesome. She weighs 48kg and has the XS using GP5000x30mm at 45psi. I recently installed GP5000x35mm with a rim that has 26mm internal width so the actual measured width of the tire is 36.5mm...there is still around 1mm clearance between the chainstay and tire sidewall. This is an awesome combination at 45psi for me with a body weight of 84kg.
my Winspace C5 is fast, stiff, and responsive, with great acceleration and confident handling. The aero frame holds speed well, and the bike stays comfortable on longer rides. Build quality is excellent, making it a strong performance bike at a great value.
I bought the frame and equipped it with Shimano 105 Di2, Magene powermeter, aero handlebar and 65 mm deep PRO-X carbon wheels with Pirelli tires. The weight is slightly over 7,6 kg.
The paint job looks absolutely insane, especially in bright sunlight! The ride itself is comfy and rapid at the same time. I'm very happy with this purchase.
