Adventure Cycle Jamis Bicycles
Jamis 2017 Dragonslayer 27″ Sport
A 27.5×3” tire measures out to a 29” diameter and a 26×3” tire measures out to a 27.5” diameter. Combining them with a 40mm rim, results in the ultimate combination of traction, roll-over and versatility without being too heavy, too bouncy, too tall or feeling lethargic on the trail.
REYNOLDS 520 STEEL
For well over a century, Reynolds has been at the forefront of cycling design and engineering continually pushing the boundaries of performance. The 520 series double-butting provides both strength and weight savings resulting in a smooth riding frameset.
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.
ADJUSTABLE SLIDING DROPOUTS
Our sliding dropout allows for 15mm 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.
READY TO LOAD
The Dragonslayer and Dragonfly frames feature rear rack eyelets and enough cargo/water cage mounts for the option to load up all the gear you may possibly need out there. Full cable housing guides are used to ensure uninterrupted shifting performance when using a frame bag.
OUTBOARD CHAIN LINE
A 12×148 rear hub with 3mm offset chainrings minimizes the chance of chain to tire contact with short chainstays and “mid-fat” tires without compromising any pedaling efficiency to a wider q-factor.
Benefits of a tubeless set-up are reduced rotating weight and the ability to use lower inflation pressures for greater traction without the risk of pinch flats. WTB TCS rims feature a tubeless UST “On-Ramp” profile providing a consistent fit between the rim and the tire for easy installation and inflation.
