Jason is riding the Enduro World Series with a mostly stock, high-pivot Trek Slash.

Jason is currently racing the full 2025 Enduro World Cup Series and is currently the highest ranked South African in the series. His weapon of choice for the tamer tracks will be the 140mm travel Trek Fuel EX. For the wilder terrain, he will ride this 170mm Trek Slash. Ahead of the Val di Fassa round of the series, we caught up with him for a closer look at his magic carpet, a high pivot Trek Slash.

BN: What tools and spares do you carry on you?

Leatt 38mm Riser Bars cut to 770mm, ODI Elite Pro Grips and a 40mm cSixx Enduro Stem.

BN: What is it about the Slash that you feel is the ‘special sauce’?

Jason: Well, that’s got to be the High Pivot suspension design. It gobbles up rough trails like a champ. Also, the geometry makes the ride really intuitive. This bike descends like a machine, I just need to learn how to keep up with it!

Upfront he runs a RockShox Zeb Ultimate fork set at 75psi, one token, zero compression and a ‘neutral’ rebound.

He is running the RockShox Vivid Ultimate rear shock with 175psi, minimal compression and a neutral rebound.

BN: What are you most particular about on your bike, in terms of setup?

Jason: Mostly just having the brakes biting hard and fast. I really enjoy a powerful brake, hence I bought the Mavens to upgrade from the Code brakes the bike came with.

He runs the Maxxis DH casing tyres, with an Assegai MaxxGrip front and a Minion DHR2 MaxxGrip rear.

BN: From track to track do you fiddle much with the clickers or are you more a set and forget rider?

Jason: I do a little bit of fine tuning on suspension pressures and the compression and rebound settings. Right now, I’m in a pretty good spot with it but I’m always open to tinkering to see what else might work better. // Follow Jason on IG: @jasonboulle
