Review: Rocky Mountain Slayer 70

26er Pro Reviews


Trouble stopping? Not with 203mm rotors and Formula The One brakes. What impressed me most though was how active the suspension stayed while braking over ruts, bumps and rocks. This allowed the rear wheel to stay in better contact with the ground and thus actually stop me faster. This also meant that braking on super steep chutes and runs was controlled and didn’t throw my body forward. Unlike my old Canfield F1 which had brake squat, the Slayer stays neutral under hard braking and was easier to get going again afterwards because my body was already in a good position to pedal.

Final Thoughts

I would absolutely recommend the Slayer 70. From the moment I put a leg over the saddle, barring some suspension set up, the bike felt stable and comfortable. I haven’t had a lot of time on a Santa Cruz Nomad, but from the couple of trails I’ve ridden, the Slayer 70 versus a Nomad with a similar set up, did offer me the same initial comfort level as the Slayer did. I felt a similar thing on some of the V-10’s I’ve ridden. The bikes are just very different riding. The Slayer is more in line with the initial comfort levels I’ve felt with Cannondale and Norcos. Hopefully those of you who have ridden similar bikes will understand my point.  One thing I have noticed of All Mtn/ Enduro bikes of late is the complexity of the bike set up and maintenance and the constant need as a rider to consider the bike setting almost as much as one has to consider the rock garden they are flying towards.  As someone who ride all types of bikes, and works on making user experiences natural and instinctive, I hope that as bike technology improves, part of that will include a seamless user experience that allows the rider to enjoy the benefits of a high end bike without having to understand absolutely everything technical about the bike they are on.

    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

    • John says:


      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.

  • Mark says:

    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??

  • dreggsy says:

    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?
