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 ABP suspension works great when braking hard
  • Lightweight and good response over handles

What We Don't Like
