The Trek Slash is a fantastic enduro bike that’s previously caused quite a stir in our group tests. So far, however, there was one problem: it was only available with a carbon frame. The new Trek Slash 8 changes all that. We’ve got the inside scoop.

The Trek Slash 8 in the aluminium version
The wait is over: finally, the Trek Slash 8 is available with an aluminium frame. Price: € 2,999.

It isn’t much news to report on: besides carbon, the Trek Slash will now also be available in aluminium. But it’s news many riders have been waiting to hear. Previously, the Trek Slash was only available with a carbon frame. The problem is that If you couldn’t afford the top-end model, you had to make compromises in the spec. With the new Slash 8, Trek is now able to offer a good build at a lower price point.

Although it’s an aluminium frame, the new Trek Slash 8 is beautifully shaped
The black paint job with the glossy white lettering is very pretty indeed
Like the Carbon models, the Slash 8 features a flip-chip for geometry adjustment
Despite the aluminium frame, however, Trek opted for an impractical press-fit BB

The componentry of the Trek Slash 8

A highlight of the Trek Slash models is the RE:aktiv shock with thru-shaft technology. Instead of an IFP chamber that pressurises the damping oil, the shock piston can move through and out of the shock body which significantly improves the small bump response. This shock is also featured on the affordable aluminum model. The rest of the spec is reliable and functional too. The SRAM GX drivetrain, RockShox Yari fork, and Bontrager components are tried and trusted. We would have preferred the reliable power of SRAM CODE R brakes instead of the GUIDE R, however. For the tyres, Trek is relying on their new Bontrager XR4 Team Issue rubber.

The geometry of the Trek Slash 8

Regarding geometry, the new Trek Slash 8 relies on almost the same measurements as its more expensive carbon brother, which isn’t a bad thing; after all the Slash is known for its balanced handling. We are pleased to see that Trek have increased the seat tube angle on the aluminium frame as this was one of our only disappointments with the carbon fibre version (angle TBC). Additionally, Trek added a new frame-size to close the gap between the 17.5″ and the 19.5″ model.

The new Trek Slash 8 has the potential to become a real bestseller!

Our first impression of the Trek Slash 8

The Trek Slash 8 seems to be the right bike for all those who don’t want to sacrifice riding performance despite having a slightly lower budget. The rear linkage with its Thru-Shaft shock has already proven itself in several reviews, and the rest of the componentry is excellent also (except for the brakes). We’re very much looking forward to a test ride.
