2021 Trek Slash 9.8 XT review – A great all-rounder and a well-deserved Best Buy

The brand new Trek Slash has big shoes to fill, its predecessor being one of the most popular 29er enduro bikes on the market. We were all the more excited to find out if the new bike can hold its own against the increasingly tough competition. Spoiler alert: yes, it can! But there are a few things to consider.

2021 Trek Slash 9.9 X01 // Bike Review

The venerable Trek Slash is back for 2021, armed with more suspension travel than ever before. The new Trek Slash 9.9 X01 comes equipped with the ever-capable, 170-millimeter RockShox ZEB Ultimate fork and a custom, 160-millimeter RockShox Super Deluxe Ultimate shock, placing it squarely in the hard-charging enduro category. For me, one of the most welcome updates for the new Slash is the seat angle, which has been steepened to 75.6 degrees, putting the rider’s weight directly between the wheels—and making for a much more comfortable seated position while climbing. The relatively long reach of 486 millimeters, together with the mid-length chainstay of 437 millimeters, creates a bike that stays firmly planted while you sweat your way to the top of a mountain. But the most impressive feature of the new Slash is its impressively light weight—something I wouldn’t automatically expect from a bike in the longer-travel range, especially one with 29-inch wheels. The lightweight frame construction and ultra-light build of the 9.9 X01 version I tested was noticeable from the moment I started huffing up my first climb.

First Ride: 2021 Trek Slash 9.9

Trek was an outlier with the previous Slash when they went all-in on enduro 29. Things have changed, but the Slash stays true to its mission: Slashing.
