Our fastest ever track bike, the Koichi San II has been wind tunnel tested and has proven itself to be worryingly fast- worrying if you're riding another bike! We've blended Advanced Aero Design with high-grade carbon fibre to ensure that every last watt of your power goes straight to the back wheel.
If you're serious about track cycling then you need a serious bike. Equipped with aero spoke front and disc rear wheels the Koichi San will help you slice through the air for the win. Designed for our sponsored pro riders the Koichi San II delivered an 11% reduction in drag in the wind tunnel compared to their previous Cervelo track bikes. The only question you have to ask yourself is how serious about winning are you?

Designed to cater for every type of rider, from pursuiters, sprinters, points/scratch and TT riders with sizes to fit all, (5'3" to 6'1"). The CM measurement for each frame size is an effective composite measurement that allows you to match against your road bike frame size.
|Rider Height||Suggested Frame Size|
|5′3″ to 5′6″||Small 49cm|
|5′5″ to 5′8″||Med 51cm|
|5′7″ to 5′11″||large 54cm|

All frame size recommendations are approximate. A good fit will also depend on the correct choice of stem length, correct bike set-up for the rider and riding style.
Correct frame size choice can also depend on a rider’s torso and limb length.
Forks are supplied for track use only. They are not drilled for front brake use.
