Ballistec carbon frame, Lefty 2.0 fork, Shimano SLX 2x11, lightness, speed, rigidity.
The Cannondale F-Si Carbon 4 is a top racing model destined for victory. The Ballistec frame F-Si Carbon 4 is extremely stiff and at the same time light. The frame is complemented by the Cannondale Lefty 2.0 fork, which excels in its rigidity and precise operation. Shimano SLX components ensure precise F-Si Carbon 4 shifting. For maximum comfort and convenience, the wheel has OutFront geometry, which has a more angled head angle and a large axle offset on the front fork. This solution increases stability, speed and maneuverability of the Cannondale F-Si Carbon 4.
XC dexterity is related to the stability of ALL-MOUNTAIN bicycles
OutFront geometry combines the best of both worlds: stability on hectic descents and speed and agility anywhere else.
PERFECT TRACTION without compromise
Our own bicycle drive solution is created with a very short rear structure, which provides perfect traction and agile steering. At the same time, however, the space for the permeability of the casing or the possibility to use a double converter is not endangered.
Explosive stiffness
Simply no flexion where energy is lost. The F-Si Carbon is the strongest bike thanks to the Ai rear wheel, short rear construction and Ballistec carbon construction.
The best xc fork
Incredibly stiff and precise. Lefty outperforms any other flexible XC competition in steering precision and cornering. Thanks to the large axle advance, the geometry of the bicycle is a key part of OutFront.
DIAMETER of bicycles according to height
To achieve the best possible driver's position for all rider figures, the small frame sizes are fitted with 27.5 "wheels, sizes M to XL have 29" diameter wheels.

All bicycles at the MTBIKER shop are new, not-ridden, from an official distributor and with a full warranty. Several brands even offer a lifetime warranty on the frame after registration. We perform all warranty services in MTBIKER stores after personal delivery or after sending the bike (or its part) by courier.
- The bicycle is taken out of the manufacturer's box
- The bicycle is assembled, inspected and adjusted (front and rear derailleur, shock, fork, wheels,...)
- The bicycle is carefully packaged back into a box and shipped
- If you order a bike for in-person pick-up or home delivery, the bike will be waiting for you assembled and checked
- If you order a bicycle via courier to your home address, the following must be done at home:
- Take the bike out of the box and carefully remove safety material and foils
- Mount handlebar to stem (1 minute, 4 or 5 mm hex hey is needed).
- Mount front wheel to fork (1 minute, without the need of any tools if the bike has a quick release).
- Loosen the screws in the headset, straighten the stem with the front wheel, tighten the upper screw on the fork and then tighten the headset (2 minutes, 4 or 5 mm hex key is needed).
- Mount the pedals to the cranks while lubricating the thread and carefully mounting it the right way (1 minute, 8 mm hex key or 15 mm wrench).
- Mount seat post to frame (10 seconds, without needing any tools if the frame has a quick link).
- Inflate the tires or fork and shock to desired pressure (2 minutes, pump needed).
- Check the tightening of hex keys and quick-releases (2 minutes, 4 and 5 mm hex key is needed).
- Go for a test drive! Handle your bicycle carefully until you get used to it. If the bike has disc brakes, their performance will be limited from now on - they will gain their full power after 4-5 strong brakes at higher speed.
