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 road 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.
Optimal Stiffness to Weight Ratio
A completely custom frame design meant that profiles could be used, allowing for stiffness and weight to be finely optimised. The end result being a bike that is both lightweight and stiff while not giving a harsh ride.
Internal Cable Routing
Cables are routed internally for improved aerodynamics and clean aesthetics. The Sirelli frame is also Di2 compatible.
25c tyre compatibility
25c tyres strike a great balance between grip and comfort at no cost to rolling resistance.
SBC Thru Axle
The SBC Rear Thru Axle provides a stiff and secure fastening of the rear wheel. The custom design integrates a threaded hanger that can be easily replaced should there be damage.
