Up front, the RockShox ZEB Select+ fork with its burly 38mm stanchions provides stiffness and control, while the RockShox Vivid Select+ rear shock delivers consistent damping on fast, technical trails. The mullet setup featuring a 29” front wheel for rollover confidence and a 27.5” rear wheel for agile handling, keeping the Slash playful without compromising stability.
The drivetrain is equally impressive, with Shimano XT Di2 wireless electronic shifting offering precise, smooth gear changes every time, even under load. A 12-speed cassette with a 10-51T range ensures you’ve got gears for both lung-busting climbs and flat-out sprints.
For stopping power, Shimano XT M8200 4-piston brakes paired with 203mm rotors deliver reliable braking on steep and technical descents. Meanwhile, Bontrager Line Comp 30 wheels with tubeless-ready Brevard RSL SE tyres keep grip and speed dialled in across mixed terrain.
Practical touches include internal frame storage, where you can stash tools or snacks, and an angle-adjust headset plus adjustable leverage rate, letting you fine-tune geometry and suspension feel to suit your riding style. Add in a Bontrager Line Dropper seatpost for confidence on descents, and you’ve got a bike that’s built for aggressive enduro riding with everyday trail versatility.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimetres for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but are like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the Mountain bike column.
Read our bike size guide for more information on sizing.
