Rim Engineering
Depth: 45mm- Internal width: 21mm
- External width: 28mm
- ERD: 552mm
- Bead: Hooked
- Tubeless Ready
- Brake: Disc only
Effective Rim Diameter (ERD) is 552mm to ensure accurate spoke length calculation and long-term serviceability across standard 24H disc builds.
Performance Design
At 45mm depth, S45 sits in the aerodynamic sweet spot — delivering efficient speed on flats while staying composed in crosswinds and responsive on climbs.
The 21mm internal width supports modern 25–30mm tyres for improved tyre shape and cornering confidence, while the Toray T700/T800 layup provides torsional stiffness under load without excessive harshness.
- Mixed terrain and all-round riding
- Responsive climbing feel with aero benefit
- Fast group rides and sustained tempo
- Riders seeking one dependable setup year-round
Intended Use
S45 is built for riders who want one wheelset to cover varied terrain — from rolling routes to climbing-focused rides — without giving up aerodynamic efficiency.
It provides balanced performance across flats, undulating roads, and climbs, offering predictable handling and confidence in changing conditions.
- Flat and rolling terrain
- Undulating routes and mixed gradients
- Climbing with stability on descents
- All-round riders who want one versatile depth
