Sub-1kg Wheels… But At What Cost? [UPVINE Ultra D40 Review]

I tested the UPVINE Ultra 40D wheels in the challenging Italian Alps, including iconic climbs like Passo dello Stelvio and Passo di Gavia, to see if these sub-1-kilogram wheels truly stand out. My ride experience and in-house tests aimed to uncover whether their impressive 950g claimed weight translates into real-world performance advantages for climbers, especially when compared to other ultralight alternatives like the Particle GCX45. I focused on build quality, acceleration, descending agility, and crosswind stability. How did they end up? Watch the review to find out.
