LT R23-28 Disc -700C Carbon Rim Ultralight with IW/Depth 23/28mm

1.Lightweight Performance

On long climbs with an average gradient of over 8%, the minor energy savings generated by a lightweight rim during every pedal stroke eventually accumulate into valuable seconds that often decide race results. Engineered specifically for climbing-focused and all-round road riders, the R23-28 rim features a 23mm internal width and 28mm rim depth. After continuous research, development and iterative testing, we offer two mature weight versions: a 250±10g ultra-light version with a 100kg rider weight limit, and a 265±10g standard version with a 130kg rider weight limit. This hooked bead rim comes in a 20-hole specification and passes a 95J professional impact test. For customized weight tuning or technical support, please contact: sales@lighttravelcycling.com

2.23mm Internal Width---Win-Win Comfort & Low Rolling --Resistance

A 23mm internal width represents the mainstream benchmark for modern high-performance road wheelsets. Optimized for 28C tires, this rim forms a perfect aerodynamic synergy with the tire, creating a smoother transitional surface that effectively reduces air turbulence and cuts drag. The wider rim profile allows the tire to fully expand and hold its ideal rounded shape, enabling safe low-pressure riding. Riders can run 5–10 PSI lower pressure compared to traditional narrow rims. This setup efficiently dissipates high-frequency road micro-vibrations, greatly reducing hand numbness and saddle fatigue, and delivering superior comfort during long-distance endurance rides.

3.28mm Rim Depth---A Lightweight All-Round Warrior

The moderate 28mm rim depth balances lightweight construction with responsive acceleration, making it the perfect choice for routes requiring frequent speed changes and dynamic riding. Its slim frontal area delivers excellent crosswind stability, minimizing wind interference on long descents and coastal roads. Riders can fully focus on line control and pedaling instead of constantly correcting steering against crosswinds, greatly improving riding stability and confidence.

4. Integrated Molding Hole Technology & Graded Carbon Fiber Layup

The R23-28 adopts advanced one-piece integrated molding hole technology. Unlike conventional carbon rims that drill spoke holes after molding — which cuts carbon fibers and destroys structural integrity — our custom mold forms spoke holes during initial production. The continuous carbon fiber layout preserves complete structural strength and crack resistance.

This integrated hole structure delivers superior spoke hole tensile strength, exceeding 300kgf in professional tests. In extreme destructive tests, the spokes break first while the rim holes remain intact, proving that the hole structure far outperforms spoke tension limits in durability and tear resistance.

The embedded nipple design ensures full contact and uniform stress distribution across the hole surface, improving long-term durability. Precisely pre-angled hole positioning aligns the spokes, nipples and rim holes in a straight natural line after installation. Straight force transmission eliminates diagonal torsion and uneven stress wear, delivering smoother and more stable riding performance.

Tiered Carbon Fiber Layup(T700+T800+T1000)

T700 — Reliable Foundation T700 carbon forms the base structure, providing balanced toughness, impact resistance and ductility. Its excellent elongation performance prevents brittle fracture under heavy impact, making the rim durable and forgiving on rough roads. The T700 base layer delivers compliant vibration damping, avoiding overly stiff and harsh road feedback, ideal for long-distance rides and complex road conditions.

T800 — Rigid Performance Booster T800 carbon is strategically laid at key stress-bearing areas with precise angles and layer counts. During hard sprinting, climbing and high-speed cornering, T800 carbon minimizes rim deformation, ensures direct power transmission, reduces brake rub, and delivers sharp, responsive acceleration.

T1000 — Top-Level Competition Insurance As aerospace-grade premium carbon fiber, T1000 is selectively applied as reinforced patches at peak stress points, including spoke hole load zones and rim joint areas. Offering 15%–20% higher tensile strength than T800, T1000 restricts crack propagation under extreme impact, serving as the final safety barrier against rim damage at high speeds and on bumpy roads.

Delivering effortless climbing, wind-resistant descending and vibration-free cruising, the R23-28 pursues perfect all-round balance. It never sacrifices weight for extreme aerodynamics nor compromises handling for ultra-light performance. It is the worry-free ideal choice for road cycling enthusiasts, amateur racers and long-distance challenge riders.
