Slash 8 frame design and size:

Trek Slash 8 frame

The frame designs of the slash series were built for riders who wanted the adventure of a long climb and also wanted a big bike, and the Slash 8 complies with it.

The 12 speed SRAM’s GX Eagle drivetrain gives the bike needed power and allows the rider to crush rock-filled descents efficiently.

Slash 8 is an improved version, and Trek has done an excellent job putting the features and design into one build. The Knock Block system in the Slash 8 saves the frame from getting damaged with the spinning of the bar and fork. Reaktiv thru-shaft damper is extremely supple and absorbs the big hits. You can even tune the geometry of the Slash 8 with the reversible Mino Link.

The perfect bike size for you is subjective to your height. Here are some recommended sizes for different rider heights.

How does it feel to ride a Slash 8?

The bike weighs around 14.4kg and is a fast-rolling playful bike. The bike gets a lot of traction when used uphill, and the compact dimensions ensure that the bike is tracking precisely on the terrains.

Downhills are pleasantly poised and balanced in this bike, and the response on the bar is quite good. The braking system in slash 8 gives you confidence, and the suspension ensures you don’t get hurt in hard hits.

The bike is very agile and refined, the handling is balanced, and riders find it very playful when riding it on the mountains and different roads. The suspension is on the plush side and is good as the bike’s character is poppy, and it demands plushy suspension.

What We Like

  • Agile and sporty
  • It’s easy to handle
  • The ABP suspension works great when braking hard
  • Lightweight and good response over handles

What We Don’t Like

  • The brakes are not good enough.
  • The bike fork gets indulged too much in rough trails.

The slash 8 comes at a price of  $4229, which is on the higher side. The mountain bike is packed with features and is built solidly. Thus, if you are someone who loves mountain biking and wants a good mountain bike, this is a good option to consider.

Although the bike might seem priced higher, it is a value for money product if compared with other Enduro bikes. The bike is feature-packed and does not require very costly maintenance. Thus, it is a good investment for your passion or your sport.


The Endnote: 

The Slash 8 by Trek has been an excellent performer and has more pros than cons when it comes to the experience it gives to fellow riders.

The tyres are a little disappointing at times in damp soil or terrains, but other than that, the suspension, the 12-speed gearbox and the comfortable saddle make up for it.

Overall, the Slash 8 is a constant poppy and fun-loving bike; the speeds are good, and the geometry and ergonomics make it a blissful ride on the bad terrains.
