We wrote the book on off-road steel. Over 30 years of it. These two Dragons might look like retro rigs, but there’s nothing outdated or outmoded about the way these bikes ride with those 27.5 wheels and 120mm travel forks from Fox and Rock Shox. The Dragon frame gives as much as it gets: the harder you push it, the better it feels.
44mm Head Tube
Oversized 44mm head tubes, like tapered head tubes, offer many advantages impacting the handling and performance of the bike. Not only do they allow for the use of tapered steerer forks adding more stiffness, lighter weight and better tracking in rough terrain, but the larger diameter provides a better surface area to weld the main triangle tubes to.
Disc Brake Reinforcement Brace
Dragon features a chainstay/seatstay disc brace that supports our thin-walled, non-driveside stays from loads generated by the disc brakes. The brace is light, strong, clean and provides vibration-free braking.
Adjustable Sliding Dropouts
Our sliding dropout allows for 20mm of adjustment. Slide your rear wheel back to increase clearance for larger tires or remove all those gears and shifters and simply tension your chain for a quiet single speed ride!
142 x 12mm Maxle Thru-Axle
Securing the rear wheel to the frame by threading it into the rear drop-outs is not only safer, it’s stiffer. Increasing the rear axle diameter from 10mm to 12mm makes it only stiffer still. The rear wheel tracks directly in line with the frame, for more precise handling, so you can go faster with more confidence. The 142mm hub drop outs provide a self-centering feature for the rear wheel for faster, easier installation.
Jamis Lock-On Grips
Our Lock-On grips offer dual lock-on security to ensure no twisting, sliding or migrating even in the roughest, steepest and wettest terrains.
180mm Front Rotors
Bigger wheels generate more rotating mass once they are up to speed. So it only makes sense to use larger rotors to help control that larger wheel in the most efficient manner possible. Sure, 160mm rotors will stop the bike. But when you’re riding like every second counts, braking for the shortest time possible while keeping the bike under control is the goal. And a larger 180mm rotor up front let’s you do this.
Reynolds pioneered the techniques of making butted tubing around the turn of the century and their 531 manganese-molybdenum alloy tubing was the standard of excellence for many decades. The Dragon Pro features a new generation of Reynolds steel: 853 seamless, air-hardened/cold-worked chrome-moly frame tubes. On the Sport, it’s Reynolds 520 double-butted.
Taking advantage of the high tensile strength of steel without having to worry about strength degradation due to welding is incredibly liberating. Welding steel often results in a 40% strength loss, requiring thick tubing walls as an offset. Not so with the air-hardened Reynolds 853 steel alloys used on our Dragon Pro. This material actually gets stronger at the weld zones, allowing Reynolds to draw the tubing thinner for a lighter, stronger frame.
