The Champ’s race whip!

Keira Duncan is the 2025 National Enduro Champion and will be lining up for round five of the Enduro World Cup in Italy this weekend. His weapon of choice for the two days of racing is the 170mm PYGA Slakline HP4. Made in South Africa, this is a bike that Keira has spent many hundreds of hours racing and riding, in Europe and at home, to help PYGA develop it.

Of course, there’s a real chance of flats so under the top tube is a loaded plug and CO2. As far as tyre inserts go, Keira runs a Panzer, but only in the rear wheel.

Strapped to the downtube is a tube and if you are reaching for that it’s usually a sign of a real bad day in the office. Keira also carries a multi tool and 10ml of chain lube.

Keira uses SRAM Code RSC brakes with 203mm rotors by Galfer.

We asked Keira what part of his bike setup he is most particular about: “Tyre pressures, they have to be right for optimal traction. Overall, I like to get my bike setup to be as comfotable as possible and then I leave it most of the time. On the odd occasion, I might change rebound and compression, slightly, for different terrain.” //
