The Slasher! First Impressions of the Trek Slash 9.8

The not-so-minor details


Trek Slash 9.8

Big-hitter, but without the weight. P-lush suspension package.


Spoke tension seems a little so-so.

Later this week, Flow’s boarding the big white budgie and heading to Queenstown, New Zealand, for a few days of exploring the trails of that famed adventure wonderland. Queenstown offers up a whopping mixed bag of trails, but the gravity riding is the real highlight, with gondola-accessed downhill tracks and mammoth heli-biking back-country epics.


For this mission,we knew we wanted to take a bike that wouldn’t wring its hands when presented with some pretty full-on terrain. Our usual Flow Nation bikes, while superb trail bikes, just don’t have the travel for downhill work, so we had a look at some other options. This bike grabbed us by the lapels and screamed in our face: “PICK ME!”

The frame is carbon throughout, with the exception of the chain stays. Flipping the Mino Link at the top of the seat stay will switch the head angle between 65 and 65.5 degrees.

The Slash is Trek’s most aggressive platform before you leap into the full-on downhill realm with the Session. It’s a real gravity enduro machine – we’d shirk to call it an all-mountain bike, because its performance heavily skewed towards descending. Heavily skewed, but not heavy: this 160mm-travel beast weighs in at 12.7kg. Its angles are all about stability when it’s fast and steep, with a head angle that’s adjustable between 65.5 and a 65-degrees.

Fork travel is adjustable from 160-130mm on the fly.

Piloting a 65-degree head angle uphill is sometimes a bit like pushing a wheel barrow with a flat tyre full of water; it’s a pain in the arse to keep on track. So to sharpen climbing performance up, the Slash has a travel-adjustable Pike that lowers the bars and sharpens the steering a bit.

The Slash 9.8 runs a SRAM X1 11-speed, single-ring drivetrain, so the front derailleur mount gets this neat cover.

We’ve fallen in love with the performance of Bontrager’s XR4 tyres. These things hang on like a cat over water, especially when they’re mounted to a wide rim, like the Bontrager Maverick. We’re predicting a lot of grip!

It’s almost odd seeing a Trek dual suspension bike that’s not equipped with the FOX DRCV shock we’ve come to know so well. While we like the DRCV shock, we do think that the Rockshox Monarch Plus is a better option for this bike; it has a bigger air and oil volume, and more progressive spring rate than the proprietary FOX dual-chamber shock, so it’s better suited to hard, rough long runs.

With four days of EnZed’s finest coming our way, we think we should be able to give the Slash a pretty good shake down and get our head around its strengths and weaknesses. A review will be coming your way, maybe even before Santa arrives.
