Jamis Dragonslayer – 27.5+ Review & Interview

A few months ago, I had a chance to ride a Jamis Dragonslayer Sport that my friend Billy purchased this year.

I was very interested to see how this 27.5 x 3 inch steel hardtail rode after testing a great variety of #plusbike models over the last two years, both for this website, as well as Bikepacker.com

Two years ago, I posted this article about the Dragonslayer release and have thought it would be an outstanding bike for most riders looking for a trail bike that could go all day and be very suitable for #bikepacking.

The 2017 Dragonslayer Sport is a great value with a MSRP of only $1399 (specs listed below). It rode very well when I threw a leg over it, and felt like a monster truck of a trail bike to me. It climbed loose trails with no problem and even smooth trails didn’t feel too sluggish compared to a normal, lighter weight 29er. It descends with the best of the hardtail trailbikes I have ridden (check out our Plus Bike List that is updated regularly to see more in this class).

Billy is FAST on this bike. He often challenges me on our Monday night group rides, coming up with lots of speed on our roller-coasterish hills to see if I can hang with him. Its usually 50/50.

Take a look at the video below where I ask Billy about his Dragonslayer, why he chose this one instead of something different, where he plans to use it, and what he upgraded within the first year of ownership.

    Wow, I wish I had given this bike a closer look before I bought my Surly Karate Monkey. I love my KM but that’s a lot of value packed in there. Looks like a better option than the Pro also. You don’t get the dropper but the bike overall weighs less. Recon is a very decent fork also.

    Hello! Very cool bike. I’m wondering about buying this Jamis, but I have a problem choosing the right size. I am between size M and L. I would prefer to choose L but it has a standover high about 840 mm. I’m 5’11” with 33” inseam. Unfortunnely, i can’t fit this bike in my area. So, could You tell me what size this frame is and what is the rider height and inseam?

      Hi Lukas! Thanks for the comment.
      Here is what my buddy Billy said about his bike.
      “Yes, it’s a large. It’s probably a little small for me, but XL is hard to resell and I’m used to the bit smaller frame. Plus it kind of gives a little bit of a ‘BMX’ feel going down stuff. I’m 6’2″ with long legs, not sure inseam.”
      I am actually 5’9 and it actually wasn’t too large for me. I didn’t notice the standover being painful for me with my 31″ inseam, but I wasn’t on uneven ground, nor did I spend too much time straddling the bike. I was mostly just riding it. 🙂
      I hope that helps!

        Hi Nick! Your answer helped me a lot. This bike is supposed to be a bikepacking machine for me, and so far on all my trips I rode on a cyclocross bike.
        The seller in the online store suggested for me the size of M, which raised my doubts. Now I decided on L. Thanks a lot.

          Glad to help! Enjoy your new bikepacking machine! Would love to hear of your travels with it. Please post up a ride report when you can!
