Winspace SLC5.0 Frameset
SLC5-Light Meets Aero
SLC5 is the next evolution of the all-round road frame-engi-neered for riders who demand uncompromising speed, precision, and control.
Every line, every surface, every gram was shaped with purpose-deliver-ing aerodynamic efficiency, race-proven stiffness, and ultra-responsive handling in one integrated platform.
From its meticulously optimized tube profiles to its advanced carbon layup using M46, M65, T800, and T1100 fibers, SLC5 is built for high-performance riding on every terrain.
Climb harder. Descend faster. Sprint with everything.
SLC5 isn't just ready for the ride-it's engineered to lead it.
The head tube features a narrow, deep profile that minimizes frontal area while directing clean airflow toward the top tube and down tube junction. Its cross-section was optimized to reduce separation in crosswinds, contributing to more stable handling at speed.
The down tube tapers progressively from top to bottom, with a truncated airfoil design that maintains airflow attachment along its length.
At its upper section, the tube captures air coming off the head tube and top tube with minimal turbulence. Further down, the shape flares slightly to accommodate bottle cages while still maintaining a clean flow path. The curvature was validated through iterative shaping and confirmed in wind tunnel tests.
The seat stays were dropped and flattened to reduce drag and manage wake behind the rider.
Their low attachment point reduces frontal exposure and creates a clean path for air exiting between the frame and the rider's legs. The stays' wide-set stance also contributes to lateral stiffness, ensuring responsive power transfer during out-of-saddle efforts.
Finite Element Optimization
SLC5 blends M46, M65, T800, and T1100 carbon fibers in seven distinct layup configurations, targeted precisely across key frame zones.
TESTED IN JAPAN. PROVEN IN THE UK.
PERFECTED FOR EVERY RIDE.
Some brands claim aero. We prove it.
To validate the SLC5's aerodynamic performance, we conducted repeated wind tunnel tests in both Japan and the UK, using different facilities, proto-cols, and control standards.
We didn't cherry-pick the best results— nor hide the worst. Instead, we ran multiple trials, refined variables, and calculated scientifically averaged values to reflect real-world performance.
for us, aero isn't marketing it's measurement.
The results speak for themselves.
Compared to its predecessor, the SLC5 achieved a 0.011 reduction in CdA and saved over 13 watts at 48 km/h. More importantly, these gains were consistent across multiple tests, riders, and conditions.
We didn't build this frame to win in simulations. We built it to win on the road.
SLC5 isn't just fast-it's proven.
