Cannondale F-Si Carbon 3 29er Mountain Bike 2019 Vulcan Green

Season:2019

Brand:Cannondale

Code:C25309M30CD19

The Cannondale F-Si has always been about pushing the limits of what an XC hardtail is capable of, and the new version pushes it harder and further than ever. No other hardtail descends as fast, climbs as nimbly, or kicks harder, smoother. With the otherworldly performance of the new Lefty Ocho, you've got a whole-new level of XC capability, tailor-made to feed the needs of the XC obsessed.

At just 900 grams, the all-new F-Si is the lightest mountain bike frame Cannondale have ever made. It shaves 80 grams off its predecessor, and when you factor in the svelte new Lefty Ocho, you save a whopping 330 grams on the frame and fork. What's even more impressive is that, rather than chasing marketing grams, Cannondale engineers focused on features that deliver real performance benefits out on the course - features such as Ai and OutFront, or improved compliance or improved durability. That's what wins races,  not saving the weight of a few sips of water.

The all-new Lefty Ocho is the smoothest, stiffest ultra-light XC fork ever made. It floats through chop and steers through the choss like nothing else.

Short chainstays do wonders for traction and nimble handling, but they usually come at a cost. Not with Ai - this proprietary Asymmetric Integration drivetrain offset moves the gears and rear triangle over, helping creating space for much shorts stays while still having the clearance for big tyres and 2x drivetrains if you so desire. It even creates a stiffer, stronger rear wheel by evening out the dish.

Lefty Ocho - Suspension of Disbelief

The all-new Lefty Ocho is simply the most advanced, smoothest, most precise-handling ultralight XC fork ever made.

With its single-crown structure, the all-new Ocho is one of the absolute lightest XC suspension forks in the world. With just one crown and one leg, all material is concentrated where needed for strength and stiffness, making it one of the lightest suspension forks in the world - 250 grams lighter than the previous Lefty. Less un-sprung mass than traditional forks also helps for a better suspension response. Complete with a tapered steerer for lighter-weight and total compatibility.

When it comes to smoothness, Ocho stands alone. Fewer friction-causing bushings and seals than any other fork, a supple new Chamber damper. And the new Delta Cage needle bearing telescope assembly. It all adds up to the smoothest fork ever made. No sticking, no binding, no shuddering or hesitation, no matter how hard you push it. Just pure, smooth action always, for ultimate control.

Ocho is the stiffest light-weight XC fork in the world, tuned for unprecedented precision and control on even the nastiest World Cup courses. Ocho's unique single-crown design and triangle-in-triangle telescope, give us unprecedented ability to tailor the stiffness of the fork. for the stiffness to go, and the give to flow.

Getting the right fit

The right size bike for your body size is essential to ensure the optimum experience, comfort and enjoyment as you ride. With sizing varying between the type of bike, the brand and even the model, getting the perfect fit can seem daunting. That’s why we’ve compiled a handy guide to help you get the correct size. 

Measure Your Height

Our handy size charts match your height to the appropriate frame size so you need to be sure you’ve measured your height accurately.

  1. Take off your shoes and stand with your back against a wall.
  2. Make sure legs are together and your shoulders are back.
  3. Place a pencil on top of your head and mark the wall (the best and easiest way to do this properly is with a friend to help you).
  4. Measure from the floor to the pencil mark you have just made with a tape measure.

Range of Reach

For most people to get the right frame size, measuring your height will suffice. However, you may find that your height is on the borderline of the range we suggest for a particular frame. If this occurs you need to measure the range of your reach or “Ape Index”. This will ensure you get a comfortable distance between the handlebars and your saddle.

  1. Stand up straight with your back against a wall.
  2. Life your arms out horizontally either side of you.
  3. Measure the distance from fingertip of one hand to fingertip of the other. This will give you your arm span.
  4. Subtract your height from this figure to get your Ape Index.
  5. If the result is positive (your arm span is greater than your height) you should go for the larger size of bike.
  6. If the result is negative (your arm span is less than your height you need the smaller size.

Stand Over Height

You should also consider your inside leg measurement when choosing your bike to ensure adequate stand over height. Stand over height is the clearance between the top tube and the bottom of your crotch. For mountain bikes we recommend a distance of 2-4 inches and for road or hybrid bikes 1-2 inches of clearance is required. This will ensure comfort when you’re stopped and standing astride the bike.

Our bike sizing charts take stand over height into consideration but if you have a particularly long or short inside leg measurement in relation to your height you will need to bear this in mind when selecting your frame size.

Riding Style

The way you ride and the type of bike you are into will also impact the frame size you should choose. For example, a trail devotee looking for an aggressive ride may prefer a smaller, more manoeuvrable bike size. It all comes down to personal preference and how the bike feels to you.

Our sizing charts aim to be as specific as possible so you can look up the particular type, make and model of bike you’re looking for. Remember, the sizes given in our guides are suggestions and should be used for general advice only. For the best possible fit  we recommend popping in to your local Leisure Lakes Bikes store, or call 0800 083 0888 for expert advice tailored to you.
