Review: Rocky Mountain Slayer 70

26er Pro Reviews

My mountain biking background has been dominated by downhill. Though as I’ve grown older and acquired more responsibilities, 20ft step downs and riding hell bent over nasty rock gardens just doesn’t have the same thrill that it used to. So I’ve been on a hunt to find a bike that will allow me a bit of the DH fun while reducing the pain and agony of hill climbs. The Slayer caught my attention for many reasons, but mostly I hoped the relaxed downhill geometry would allow me to ride all the local DH trails as well as the XC/All Mountain ones. For those bikers in the Bay Area, being able to go from Demo to Tamarancho to Pacifica, all on the same bike.

I’m 6’4” and am fairly comfortable with a smaller cockpit, so I asked to test the 19-inch frame. And while it works, I’m not too cramped and have ample legroom, if I had the option to have re-asked for the 20.5-inch frame, I should have. Being spread out another 1.5-inches would make hill climbs slightly more comfortable, but on the downhill the smaller frame is just that much more maneuverable.

The spec’d components on the top of the line Slayer 70 are fantastic. Formula The One disc brakes, SRAM X9 derailleur and 10 speed gearing, Fox 36 Float RLC Fit with Kashima coating, Fox RP23 XV with custom valuing and Kashima coating, DT Swiss EX 500 Tubeless compatible rims, and the ‘never-going-back-to-a-standard-seatpost’ RockShox Reverb. The 19-inch frame weighed in at just about 30lbs, and if one was inclined, there were some obvious weight saving options. For instance a 203mm rear rotor is a bit over kill, and if you have the legs for it, converting to a single ring up front would shed more weight. One could easily have a 28lbs, 160mm trail destroying machine. The only thing I found I would change out immediately is the 28-inch handlebars. 30-inch bars are a much better fit for this bike.

    Nice review, very informative. I’m seriously considering buying one of these since there are some really good deals on them right now. I’m 6’2 and not sure if the 19′ or 20.5′ would fit me better. I know the top tubes tend to run a little shorter than on some bikes, plus the straight up geometry. I cant seem to find one near me to size up. Any slayer owners out there let me know what you think. Thanks

      Rob – you should be on the 20.5 bike. No question that Chris Stenger is right (although a bit harsh) and the reviewer was on a bike that was a tad small for him

      I am 6’2” with a 34 inch inseam average arm length and ride a 20.5. 19 would be to small

  • Ruder says:

    Chris nice review…. but at your height you s/be on an XL sized bike ! :-)
    I’m 6″2″ and I couldn’t imagine riding a 19″ bike. Did you bend the seatpost on that bike ? :-)

    I just saw this site for the first time, I happened to be at Dealer Camp in Utah today and rode the Slayer 70, so this article caught my eye. I’m sure the reviewer is a great guy but having a SS guy review a Enduro/DH bike, mention that the front wheel comes up on steep climbs is sort of silly for obvious reasons, not to mention he picked a frame size at least one too small. I’m not a techno geek but the improvements in aggressive descending bikes in the last several years has been amazing. Lock out switches are great, ditto the adjusters on my hydraulic disc brakes, etc. Seriously dude, if you don’t get the downhill scene that’s okay but you probably shouldn’t review this bike and stick to single speeds. But thank you for the technical info it was very well written and don’t get mad at me :) everyone has their own opinion, just voicing mine. Peace.

    Per the feed back I’ve adjusted some of the comments in the review and have moved my concerns about all the gadgetry into the final paragraph.

    I’m about 5′ 10″ tall and am wondering if the 18″ bike would be a good fit. I don’t have a dealer close by to get a good idea. Any suggestions??

    I’m thinking of putting a chain device on mine, as it seems to drop alot in 2 x 10 mode, what have people out there been using on theirs?
