Prolite 66 Triple Butted Aluminum
Proven high-end aluminum (6066) is extremely light and strong. Using triple-butted wall thicknesses and hydroforming technology, aluminum tubes can be fine-tuned to provide the best possible stiffness-to-weight ratio.

HFS - Hydro Forming System
Tubes are inserted into negative molds and a hot emulsion of water and oil is forced under pressure, enabling them to form complex shapes.

X-Taper Headtube
The X-Tapered headtube provides space for mounting a tapered fork. Tapered forks offer exceptional stiffness and precision and provide confidence-inspiring steering.

Smooth Welding
Sometimes called "double pass welding," a second pass on the weld gives the frame a clean, organic look. At first glance, you'll be convinced it's carbon.

Internal Cable Routing
Cables are routed through the frame, going in and out through smooth sockets. The bike has a clean look, while the cables are protected from moisture and dirt.

Smart Entry
Cables, housings, and brake hoses are tightened under tension to prevent rattling when trails or roads get rough. All inputs are fully interchangeable to handle Di2, hydraulic hoses, brake cables and shifting cable housings, etc.

DI2 Ready
Bicycles/frames with the "Di2 Ready" symbol are prepared for installation of Di2 technology by mounting the battery in the seatpost or inside the fork.

Bikes equipped with F-Mount have integrated fender fittings (some bikes require model-specific fenders), making installation quick and easy.

Integrated mount on the chainstay to mount a MERIDA kickstand (or any commercial kickstand).

Bikes equipped with "C-Mount" have attachment points for a rear rack already built in (some bikes require a model-specific rear rack), making mounting fast, easy and reliable.

Casting Motor Bracket
Sophisticated shape possible only through casting technology, creating an integrated appearance and extremely strong connection between the motor and electric bike frame for improved performance and reliability.

Energy Guard Twist
Twist Lock mechanism located at the top end of the "Energy Guard" battery cover for easy locking and unlocking of the protective inner battery cover.
