The Mk.1 chassis are out of stock and will not be made again.

The K31-XXI lightweight chassis are out of stock, and will not be manufactured again. But there are good news – – –

The ultimate Mk.2 chassis are coming in 2024!

We are working on Mk.2 chassis, which we hope will hit the market by end-spring 2024. In our trademark “high speed low drag” spirit, these will be even more ultimate than Mk.1 (yes, it is possible!)

To be informed of the new developments and of the new chassis availability, do not hesitate to subscribe to our mailing list here: https://lk2236.ch/en/my-account/
