MPH BRAKE SYSTEM
HYDRAULIC POWER FOR ALL
The hybrid mechanical - hydraulic MPH Drop Bar Brake System provides an accessible entry into hydraulic disc braking, operating via a mechanical lever but offering as much as 20% more power than a mechanical only disc-brake system.
DURABLE PERFORMANCE
MORE POWER
Via an increased master cylinder and caliper piston ratio and increased force on the calipers, the MPH Brake System delivers up to 20% more braking power than mechanical only systems, offering comparable performance to full-hydraulic Shimano 105 disc brakes at a more accessible price point.
BETTER CONTROL
With a linear braking curve, the MPH Brake System ensures braking power increases steadily as you squeeze the lever, providing smooth and precise modulation. A refined brake pad compound also prevents heat-induced brake fade, further enhancing power and control.

ALL-WEATHER RELIABILITY
The MPH Brake System is engineered for reliable performance in all weather conditions. It’s dual-compound brake pads and specially designed rotors deliver an ideal balance of power and control, minimizing the risk of wheel lock-up. In wet conditions, braking performance rivals that of a full hydraulic Shimano 105 disc brake system.

STREAMLINED SETUP
Compatible with both internal and external cable routing, the master cylinder integrates directly with the Contact AeroLite stem—no adapter needed—cleanly guiding external cables beneath the stem for an aerodynamic setup. With a vertical adapter, it can also be configured for externally routed cockpits.
Cables routed externally with available vertical adapter.

HYDRAULIC POWER FOR ALL
The MPH Brake System provides an accessible entry into hydraulic disc braking, operating via a mechanical lever but offering as much as 20% more power than a mechanical disc-brake system.
KEY FEATURES
• Operates a hydraulic brake system from a mechanical brake / shift lever or converts a mechanical disc brake setup to a semi-hydraulic system without the need to replace brake and shift levers.
• Cable-actuated master cylinder blends the simplicity of mechanical disc brakes with the power and smooth feel of hydraulic.
• Balanced lever pull allows riders to modulate braking power and speed with more precision and ease.
• Even under heavy use or long, steep descents, braking power doesn’t fade.
• Optimal braking performance in all conditions.
• Easily mounts onto a Giant Contact AeroLite stem faceplate for an integrated, streamlined look.
• Compatible with externally routed cockpits via available adapter.

GRIT CORE LITE SADDLE
GRIT CORE LITE SADDLE
VENTURE FURTHER
The Grit Core Lite saddle is designed for smaller riders on road, gravel and mixed terrain. Its crowned shape enhances pedaling space, while the raised rear section offers optimal support and promotes an aerodynamic riding posture. An ergonomic center cut-out reduces pressure on sensitive areas, ensuring all-day comfort.
COMPACT COMFORT
The Grit Core Lite saddle is designed with a shorter and narrower shape, tailored for the pelvic width and shorter reach bike geometries of compact riders. This ensures maximum comfort while maintaining an efficient riding position. With supportive and comfortable padding, an ergonomic shape for balanced weight distribution, and a central cut-out that reduces perineal pressure, the Grit Core Lite delivers all-day comfort across any terrain.
MAXIMUM EFFICIENCY
The saddle’s narrow crowned shape minimizes inner thigh interference, while the shorter nose facilitates greater movement, allowing for enhanced pedaling efficiency. High-elastic PU foam padding sits on a durable recycled PU base, offering sit bone support for lighter weights, damping vibrations from the terrain for a smoother ride, and promoting efficient power transfer.
FAST REACTION
The Grit Core Lite’s smooth-edged design minimizes friction and interference with the inner thigh during fast movements or sprints. A subtle upward curve at the rear ensures strong ischial support, promoting a more efficient and aerodynamic riding position.

WHEELSYSTEM
SURE FOOTED SPEED
The SLR 1 40 650b WheelSystem delivers the same lightweight efficiency and aerodynamic advantages as its 700C counterpart, but is specifically designed for smaller frame sizes. This performance road wheel offers rapid acceleration and nimble handling—making it the perfect choice for small riders taking on big challenges.
LIGHTWEIGHT
Optimized carbon layup with high-tensile-strength carbon fiber strategically places reinforcement at critical stress points, creating a stiff, lightweight structure. At just 1300g, the 650b option further reduces the weight, making it ideal for smaller bikes and lighter riders.
The SLR 1 40 650b WheelSystem features a lightweight carbon rim specifically tuned for smaller frame sizes and riders. Its smaller diameter and shorter spokes offer increased stiffness and better transmission efficiency.
CONFIDENT
A strategically optimized carbon layup reinforces key stress zones with high-tensile-strength fibers, enhancing strength without adding weight. The hookless rim design forms a continuous, robust structure for lightweight durability, while the 22.4mm inner width and wider 2.8mm bead provide better tire support and more confident handling on road and mixed terrain.
SLR 1 40 650b DISC WHEELSYSTEM
The SLR 1 40 650b is WheelSystem built for smaller frame sizes and delivers quick acceleration, agile handling, and long-lasting efficiency—ideal for smaller riders who want top-tier road and gravel performance.
FEATURES
• 650b Rim Diameter - Optimized for smaller road and gravel frames
• Hookless Rim Design – Enhances durability and offers a wider inner rim width without adding weight.
• Optimized Carbon Layup – High-tensile-strength carbon fiber is strategically placed at critical points to provide a stiff yet lightweight wheel.
• 40mm Hookless Rim Profile – Offers an added aerodynamic advantage.
• Dynamic Balanced Lacing (DBL) Technology – Creates a stiffer, more efficient wheel with outstanding power transfer. The enlarged DBL hub flange increases spoke bracing angles, boosting overall torsional, transmission, and lateral stiffness for better power transfer.
• 2.8mm Rim Bead Width – Enhances rim stiffness, providing better tire support during cornering.
• 22.4mm Inner Rim Width – Designed for high-volume road tires, it increases the actual tire contact patch for better traction, impact absorption, and an improved ride feel.
• Giant Low Friction Hub – Precision-machined internals reduce bearing friction, lower rolling resistance, and minimize power loss.
