The UpVine Light 40mm embody the perfect balance between extreme lightness and aerodynamic performance for the demanding road cyclist. At only 1150 grams per pair, this carbon disc brake wheelset redefines segment standards, combining a 40 mm rim depth — ideal for versatility — and a Toray T700/T800 carbon fiber construction derived from aerospace technologies. Developed by UpVine in Hangzhou (China), these wheels are designed to support climbers, all-road riders and racers on all types of terrain.

Technical overview: the LIGHT series

The UpVine LIGHT range (available in 40 mm and 50 mm) is distinguished by an approach oriented towards efficiency and everyday comfort. The 36-tooth ratchet hub offers progressive engagement suited to long rides, while the 23 mm internal width rim accommodates tubeless tires from 25 to 35 mm, promoting grip, comfort and efficiency. The no inner holes construction reinforces structural rigidity and simplifies tubeless installation, while reducing weight. Resistance tested up to 160 PSI and impact resistance exceeding 100 Joules (2.5× UCI standard).

Technical highlights

• Ultra-light weight: 1150 g per pair — among the lightest on the market in 40 mm, for instant acceleration and exceptional responsiveness on climbs.
• Premium Toray T700 + T800 material: multi-layer hybrid lamination optimizing stiffness-to-weight ratio and offering competition-level fatigue resistance (30% improved stress distribution).
• Modern internal width (23 mm): perfectly adapted to current standards for 28-30 mm road tires, ensuring optimal tire shape, cornering stability and absorbing comfort.
• 36T ratchet hub: progressive engagement system with 10° angle, ideal for long-term reliability and smooth rolling. Manufactured in UpVine's proprietary hub factory (10 years of expertise).
• Reinforced lacing: ultra-light steel spokes (3.7 g/unit, 3500 N resistance) and treated titanium alloy nipples eliminating 100% of corrosion risks (sweat, environment).
• Native Tubeless Ready: rim without inner holes, supplied with tubeless valves and pre-installed rim tape — simplified installation, reinforced sealing.
• Crosswind stability: the 40 mm profile is widely recognized as the aerodynamic sweet spot, offering measurable aero gains without excessive nervousness in crosswinds.

Geometry and standards

• Axle standard: Thru-axle 12×100 mm (front) / 12×142 mm (rear) — modern universal road/gravel standard.
• Braking: Centerlock disc — quick and precise brake rotor installation, compatible with all Centerlock rotors on the market.
• Freehub body: Compatible with Shimano HG 11/12 speed and SRAM XDR (option to be specified when ordering).
• Lacing: Front 21 spokes (2:1 configuration) / Rear 24 spokes (2:1) — optimized tension balance for maximum lateral and torsional rigidity.

Recommended use and maintenance

The UpVine Light 40mm excel in long distance rides, hilly sportives, intensive training and amateur/elite competitions on varied roads. Their featherweight makes them formidable on climbs, while their aero profile provides a clear advantage on the flat and in fast descents. Maintenance is limited to regular checking of spoke tensions, gentle cleaning of carbon surfaces and checking ratchet lubrication (grease supplied). 2-year manufacturer's warranty covering manufacturing defects, with free replacement of defective components (rim, spoke, hub) during this period.

Available variants

• UpVine LIGHT 40mm (1150 g) — 40 mm depth, ideal for mountain/flat versatility and crosswind stability.
• UpVine LIGHT 50mm (1250 g) — 50 mm depth, oriented towards enhanced aerodynamics for riders on fast and flat terrain.

Both depths share the same architecture (T700/T800 carbon, 36T hub, 23 mm internal width, tubeless ready, Centerlock disc braking) and are aimed at slightly different cyclist profiles depending on the priority given to weight or aero.
