ULTIMA SE 50.55
Introducing the all-new 2026 R-Series wheelset, engineered from the ground up to be lighter, stronger, and faster than ever.
At just 1470 grams with a new 125kg max load rating, this wheelset delivers serious strength without the weight penalty.
The carbon rims are built from a Toray T700 & T800 fiber blend with 3K weave, striking the perfect balance of stiffness and durability.
Featuring mixed 50|55mm profiles; a deeper rear for enhanced power transfer and stability, paired with a shallower front for improved handling responsiveness and reduced rider fatigue.
Powering it all is the all-new R-Series ratchet drive freehub, with 45-tooth engagement for faster power transfer and reduced torsional strain, ensuring a longer service life for the whole system.
The 21mm internal-width rim features a hooked, tubeless-compatible bead design that lets you run wider tyres across a broader pressure range without fear of blow-off, while the wider profile makes tyre installation and removal effortless.
Our high-TG (255°) resin brake track resists heat build-up for reliable stopping power, while grooved channels clear moisture in wet conditions, delivering stronger braking with less lever effort and up to 30% shorter stopping distances.
