A premium carbon‑spoke disc‑brake road wheelset achieving masterful balance of aerodynamics, stiffness and low weight for competitive road riders chasing maximum efficiency and real‑world speed gains.
Drive SL CS series features 25 mm internal hooked rim width, optimized for modern 29‑32C road tyres. Run lower tyre pressures for plush long‑ride comfort without sacrificing aerodynamic performance or cornering support. Each wheelset is built around a one‑piece 60‑tooth titanium freehub for sharp 6‑degree engagement and long‑term reliability, paired with ultra‑light 3.2 mm SL aero bladed carbon spokes.
Every Drive SL CS wheelset passes 20+ lab tests and UCI vertical‑impact certification, additionally validated at Silverstone Engineering Hub wind‑tunnel facility for real‑world cross‑wind stability and aerodynamic output. Two rim‑depth variants available:
- 48D‑CS: Versatile all‑rounder, mixed‑terrain, great for rolling roads and variable wind conditions
- 58D‑CS: Deeper‑profile for flat‑land speed, fast group rides and competitive racing
⚠️ Important: CS stands for carbon‑spoke version, equipped with TPI steel bearings. This wheelset accepts thru‑axle only (12×100 mm front /12×142 mm rear). Quick‑release frames are not compatible.
Why does the Drive SL use TPI steel bearings?
Designed as an all-round competition wheelset, the Drive SL is built to perform across a wide range of terrain—from steep climbs and high-speed descents to gusty crosswinds and rugged cobblestone sectors.
Steel bearings are inherently more tolerant of contamination, ensuring consistent, predictable performance regardless of weather or road conditions. Beyond durability, steel bearings deliver tangible practical benefits: they run smoothly with standard lithium-based grease, offer greater installation tolerance, and require less frequent servicing.
Benefits
✅ 25 mm Internal Rim Width Eliminates bulbous “light‑bulb effect” on 29‑32C tyres. Improved sidewall stability during hard cornering and out‑of‑the‑saddle sprints. Front‑rear asymmetric outer‑width profile balances cross‑wind handling and drag reduction. Lower operating tyre pressure delivers superior vibration damping for long‑distance comfort.
✅ One‑Piece Titanium 60T / 6° Freehub Ratchet teeth and freehub body are machined from a single titanium blank. Delivers instant 6‑degree engagement, outstanding corrosion resistance and direct power transfer. Industry‑leading manufacturing standard for carbon‑spoke performance wheels.
✅ Precision‑Tuned Hub & High Lateral Stiffness Hub‑side spoke‑tension difference controlled ≤ 7 kgf (far better than typical ≥15 kgf found on many 2:1‑pattern wheels). More even spoke tension reduces dynamic‑load deformation, improves durability. Higher lateral stiffness minimises power loss during sprints and limits brake‑rub.
✅ Race‑Validated Aerodynamics & UCI‑Approved Wind‑tunnel validated at Silverstone. Delivers measurable 1‑6 W power advantage under typical real‑world yaw‑angle conditions (0‑15°). Strong cross‑wind stability even at high speeds ≥28 km/h. Fully UCI‑approved for elite‑level competition.
✅ Light‑Weight Complete Wheelset 48D‑CS total weight: 1290 ±30 g (pair, excluding tubeless valves & rim tape). 58D‑CS total weight: 1350 ±30 g (pair, excluding tubeless valves & rim tape).
✅ Complete Factory Fitted Accessories Pre‑installed rim tape, tubeless valves plus four spare carbon spokes & alloy secure‑lock nipples included out‑of‑the‑box.
