Planet X Koichi San II

Koichi San II Carbon Track Bike

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?
