REYNOLDS STEEL
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 DZB seamless, air-hardened/cold-worked
chrome-moly frame tubes. On the Sport, it’s Reynolds 520 double-butted.
44MM HEAD TUBES
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
The 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.
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 that.
