SIRELLI FRAME

The Sirelli is a premium carbon all round road bike range with a penchant for climbing. Tubing shapes and overall design maximise the stiffness to weight ratio, ensuring that all your energy and control move the bike intuitively. Compact geometry with different fork offsets for varying sizes, ensures that the ride up and down hills is responsive, agile, stable and direct. A minimalist design, using carbon properties to their fullest to enhance the riding experience.

FEATURE

01

SBC POWER TRANSFER BB FORMATION

The BB area is made as large as possible, the down tube utilizes the full BB width for maximum stiffness and acceleration. This is helped by use of the FSA BB386EVO system.

FEATURE

02

SILVERBACK SIZE SPECIFIC FORK GEOMETRY

52mm fork offset on small frame sizes creates a stable ride feel in combination with the short wheel- base while providing more toe to front wheel clearance. Medium to extra large sizes use a 43mm fork offset to create responsive and balanced handling at all speeds, whether climbing or descending.

FEATURE

03

INTERNAL ROUTED DUAL GROUP TECHNOLOGYINTERNAL ROUTED DUAL GROUP TECHNOLOGY

Both Di2 and mechanical cabling are internally compatible on this frame by use of multi-function cable entrance guides. These guides include varying plates that are bolted in to the frame as either gear housing stops, or as a Di2 cable holder for seamless integration.

FEATURE

04

COMFORT REAR STAYS

Thin seat stays in round profiles are unidirectional in stiffness for great responsiveness, yet remain light and comfortable, perfect for long road rides in the mountains.

FEATURE

05

COMPACT RACE GEOMETRY

A shorter seat tube lowers the top tube junction forming a tighter front triangle for all sizes. This results in a lower weight and increased stiffness over a standard front triangle size. The longer seatpost extension enhances ride comfort. On larger sizes the chain stays are longer promoting better stability and comfort for taller riders.

FEATURE

06

STIFF LIGHTWEIGHT TUBING

Using tubing shapes that combine rounded corners and straighter sides, minimises carbon material used for great weight saving over squarer profiles, while retaining directional stiffness properties of squarer shaped tubing.
