The previous model of Slash, with its straight shot down tube, introduced Knock Block, a system integrated into the headset that keeps the handlebars from swinging all of the way around should a rider crash. In previous years Trek has introduced new standards and features that would change the industry for better or worse. The rear end is controlled by Trek’s exclusive RockShox Super Deluxe ThruShaft rear shock, which does away with the IFP typically found in a rear shock to deliver a shock that is claimed to “respond to changes in terrain faster than any other shock on the market”. It continues to use Trek’s classic linkage-driven single pivot suspension design, with a magnesium rocker link driving the shock, and their Active Braking Pivot (ABP) which adds a pivot around the rear axle to control the braking influence. Trek’s Slash is a 29” wheeled, 160mm travel enduro machine designed around a 170mm fork. In this review, we will put the Trek Slash 9.9 to the test to better understand its new performance capabilities and where it excels. We’ve been putting the Slash 9.9 XO1 through its paces for quite some time, and it’s clear that these changes have improved the descending capabilities considerably, but not without compromise. The previous version of the Slash was blurring the line between trail and enduro, but with these new updates there is no question that the Slash falls in the enduro mountain bike category.
TREK SLASH UPDATE
This was an important update to keep Trek’s long-legged enduro race machine relevant and competitive. Last year Trek gave their Slash the longer, lower, slacker treatment.
