Climb with ease, descend with finesse.

The Sirelli 2 has been designed with compact geometry and fork offsets optimised for big descents. The lightweight road bike frame offers efficient pedalling and all-day on-road comfort. The frame is Di2 compatible. Sirelli is a quick and nimble, great riding carbon bike, equally at home racing or when you head out for a quick coffee with friends.

Sirelli Carbon frame

The Sirelli frame is a Silverback Advanced Dynamics compact carbon road frame with a custom engineered carbon layup. This means that the frame is super light, but strong enough to be ridden hard. It features a tapered 1-1/8"-1.5" headtube, Internal Cable Routing and a replaceable derailleur hanger.

Silverback Carbon road fork

Sirelli 2 is fitted with a Silverback Advanced Dynamics carbon fork. The carbon fork further reduces weight on the bike, improves steering precision and ride comfort. Finished in UD carbon, the fork has a tapered carbon steerer and the offset is tuned to suit the nature of the Sirelli.

WHY IT’S BEST.

The Sirelli is made to climb like a mountain goat on and descend like a fish eagle. Up or down - Sirelli is a blast.
Weight, or lack thereof. The Sirelli 2 weights just 8.03kg in stock, size medium!
The Sirelli features a quality, efficient, Shimano 105 2x11 groupset.
The FSA wheelset and Vittoria tyres offer low rolling resistance, efficient power transfer to the ground and plenty of grip for superior cornering.
Sirelli has two water bottle mounts in the main triangle.
The Silverback Carbon fork with Carbon steerer is a great match for the stiff, light frame - making for an overall lighter steering, nimbler feeling bike.

ENGINEERING NOTES.

Geometry

Incline optimized geometry

Seatstays

The seatstays are designed to be slightly flexible, yet laterally stiff - providing a degree of comfort on an otherwise stiff frame.

Wheels and tyres

Sirelli 2 is fitted with a quality FSA WH-VT-302 wheelset. These are quick rolling on sealed bearings and wrapped in Vittoria Rubino Pro 700x23C tyres, suited to the Sirelli's high speed nature.

Groupset choice

A highly efficient, benchmark quality, Shimano 105 2x11 groupset ensures longevity, smooth shifting and efficient power delivery to the wheels. Smooth shifting and minimal maintenance is a given when professionally setup.

Brakeset

Sirelli 2 is designed to go fast. Going fast is great, but you need to be able to manage that speed, and Sirelli uses powerful Shimano 105 rim brakes to effectively do just that.

Weight/weight limit

Sirelli is a light bike and tips the scales at 8.03kg. This weight is on a size Medium excluding pedals but including tubes. The bike is spec'd in favour of low weight, but despite that, the Sirelli has a rider weight limit of 125kg.
