There's a New Aluminum Version of the Trek Slash

Trek Slash alloy

Ever since it debuted back in 2016, Trek's Slash 29 has been a popular option for riders looking for a burly enduro race bike or all-mountain mischief maker, but even the entry level model was on the higher end of the price scale. The introduction of an aluminum-framed model changes that, and the new Slash 8 retails for a more attainable $3,500 USD. There's also a frame only option for $1,999, which includes a RE:aktiv / ThruShaft equipped RockShox Deluxe RT3.

The Slash's aluminum frame keeps almost all of the features found on the carbon models – it still has 150mm of rear travel, and a flip chip allows the head angle to be adjusted between 65.1 or 65.6-degrees. There's internal cable routing, along with the Knock Block integrated headset that keeps the fork and handlebar from turning too far and smacking into the frame.
Slash 8 Details

• Intended use: all-mountain / enduro
• Wheel size: 29"
• Rear wheel travel: 150mm
• Aluminum frame
• 65.1° or 65.6° head angle
• 434mm chainstays

The Slash 8's component package includes a 160mm RockShox Yari RC fork, SRAM Guide R brakes, and a 12-speed SRAM GX drivetrain. The recently-updated Bontrager Line dropper post is also in place, along with Bontrager's Line 30 Comp wheels and 2.4” XR4 tires.

Not into the flashy yellow and green paint job? The matte black option will make it a little easier to fly under the radar.

Like its carbon sibling, the alloy Slash has 150mm of rear travel, internal cable routing, and a Knock Block headset.

The Trek Slash 9.7

Along with the new aluminum model, Trek have also expanded the number of carbon models – after a brief absence, the top-tier, 9.9 model returns, equipped with a full carbon frame, carbon wheels, a Fox Factory 36 GRIP2 fork, and Shimano's 4-piston XT brakes for $7,200. There's also a new 9.7 model, which has a carbon front triangle, alloy swingarm, a similar build kit to what's found on the alloy Slash 8, and a price tag of $4,500.

 I have been on mine for 2 weeks and it is an amazing value ride.. Steeper seat tube than the csrbon version and builds to a 32lbs with pedals and burly tires.. This thing rips, up or down.. A charger 2 damper going in the Fork next week but the shock is flawless..
  • 2 1
 thanks for the beta. Respect to Trek for the price point. 32 ain’t no lightweight but it’s also not 34 like the alu Sentinel.
  • 6 1
 @WasatchEnduro:
It could be under 30 with a little work.
Chainring is 32t and is Steel. An alloy one shaves weight, carbon bars, lighter pedals would put the bike around 30lbs..
But here in BC, 34lbs enduro bikes are not too out of place..ive seen 38lbs fully loaded carbon Rocky Mountain Insticts..
Im more concerned with pedalling position these days..
  • 1 0
 @denomerdano:

Interesting point. Even tho the Sentinel I demoed was heavy as hell, the pedaling position was noticeably better than my stumpjumper, to the point that the slack AF hta didn’t feel a hindrance at all whilst climbing. Cool bike. I’ll have to arrange a spin in the Slash.
  • 4 0
 I'm exactly the same, picked mine up last Thursday. I weighed a 19.5" 8 at 31.04 lbs with no pedals against a 17.5" 9.7 at 30.05 lbs. So 1lb for $1k and lower spec (nx vs gx). The steeper seat tube angle puts it almost the same as a Fuel EX. Mine is sitting at 32 lbs even with a carbon bar, chester pedals, and Maxxis 2.5" W/T DHF/Aggressor. I've also got an RC2 damper conversion coming, but its back ordered till August 10th.

I love it so much, I can't wait for Angel Fire in the morning.

 I really enjoyed the RSL Slash 9.9 I demo'ed in WBP a few CWorx back. Had I went back and tried the larger frame size out I likely would own one now.

 @denomerdano: I've never put one of my bikes on a scale. I don't know if I would be able to say if my alloy "Enduro" 29er bike weighed less or more than my carbon DH 26er bike. I'd guess the two of them are similar within a pound...
  • 2 0
 @luckyguy19: Yes Rockshox is taking their sweet time with the RC2 dampers. Yari is OK for majority of stuff, but fails to recover quick enough on rough trails..
I've had the 2.6 Goodyear Newton ST on the front which made the bike a pig on the ups but massively more capable on the downs.. With the DHF 2.5WT It is almost as capable without the weight penalty..

Other unkown feature of all SLASHes are you can run 27.5X2.8 Wheels in them no problem.. also plenty of room with 29x2.6 rubber too.. something for every trail!!

I'm nearly under 29lbs. The frame is super light. Guys pushing 38lbs are doing something dumb. The X2 I throw on it is only another 200g. I could go coil and get up to 30+ lbs but FAR from 38. My other alum bike is 33lbs and feels like a tank after the new Instinct.

 @loganflores:

Are u talking Slash or Sentinel?

denomerdano owns this bike so he knows.

I weighed a large alu gx Smuggler at the shop at 34 lbs with tubes. The Sentinel’s frame is 1/2 pound heavier and a few parts are a little heavier than the smug so I’m guessing 35-ish with tubes. The alu gx Sentinel I demoed was set up tubeless so closer to 34 lbs.

I loved the Sent and the weight didn’t put me off it just confirmed that if I go with that bike next that it would be worth the carbon version for the 2.5 lb weight savings.

Liking this Slash tho too.

  • 1 0
 @denomerdano: So close, all I ride on is loose over hard or moondust it seems. Good to know about the casing though. The Newton DH has "240" TPI so I figured with 4 layers of 60 TPI it should be pretty solid.

 "We made a thru-shaft shock so we don't need no IFP, but it turns out we still kinda' need an IFP so we put just a little one on the side of the shock"
  • 5 0
 I had this thought too! Hilarious... but my understanding is that the IFP is there to compensate to pressure changes due to temperature and has no effect on the ThruShaft damping function.

 What I like about "bigger" bike brands is how they smooth the welds. My old Trek Remedy and even 10-year old Cannondale entry-level hardtail have so smooth joints on the frame that they almost look like they're made of carbon fiber.

Raw welds have certain appeal, but I appreciate clean look more.

 I'm trying to decide between the 2019 Remedy or the 2019 alloy Slash. My last bike was a Commencal Meta V4.2 and i want a bike that i equally (or nearly) as capable as the Meta. INow I cant decide between remedy and slash, surely the slash is going to be the faster bike but how much will it hold me back, compared to the remedy, when smashing turns and going off big jumps? And how much slower is the the remedy over big chunky sections? The Slash would also be my first 29er so im not sure how big of a change that is.
  • 3 1
 When I changed from 27.5 to 29 it was quite some difference in the feel of steering and timing, but now I got used to it I would not want to go back to the small wheels.

 Just picked the new 2019 Slash 9.9. The bike rips so hard. It's my first 29er and I totally notice the monster truck like confidence that comes from the bigger wheels. Also, the matte black 9.9 is actually just a raw carbon finish which looks sick. Overall awesome bike would recommend.

 Still to slack off a seat angle...with most riders running 150 droppers why not steepen the seat angle to make the bike more pedal friendly.

 For real. Slack seat angles are fine until you ride a proper one... Or are a smaller dude. At 6-4 these slack seat angles SUCK to pedal uphill. The front wheel starts going everywhere if you arent really on it.

 The shock on my Slash 9.8 is gash. 2 rides in and it blew. It took Sram/Trek 6 weeks to replace the shock. Installed that one and spotted that it was weeping on the first ride. Hit lockout and it squeaked it’s cock off on every climb. Now on a 3rd shock since May 2018, see how this one goes.
On the plus side though, these bikes are bastard fast!
