Trail X2′s frame is made of lightweight-but-strong 7005 series aluminum tubing, featuring over-sized, ovalized & tapered tubing for increased frame strength

The sloping Enduro II frame design is offered in 9 (!) sizes, assuring the best possible customer fit for optimal handling and enhanced comfort

Our smallest 12″ frame size is especially suitable for junior riders. This frame size can comfortably & safely fit taller kids as young as 9 or 10

With the Trail X’s larger diameter 26″ wheels and 300mm seat post with quick-release clamp, this bike will last them for years

The X2′s suspension fork delivers 60mm of coil-sprung telescoping travel with a lightweight alloy crown and stout 28mm steel sliders for stiffness, strength and a straight-tracking front wheel

Weinmann’s ZAC 19 double-wall rims are light-but-durable and on the Trail X2 the strength of the box-shaped double-wall rim profile is a disc-brake must.

Bikes equipped with disc brakes in this price range are often spec’ed with weaker singlewall rims. Disc brake torque passed through the spokes can pull nipples right out of the spoke bed of a single-wall rim. Read this and know: if you want the security and power of disc brakes, make sure your rim is at least double-walled

Tektro’s IO disc brakes stop great in all conditions & increase wheel longevity by eliminating the rim sidewall from the brake system

The X2′s 21-speed Shimano EZ-Fire Plus drivetrain features a Shimano Acera rear derailleur, alloy 42/34/24 crankset & 13-28 indexed freewheel for smooth shifting, easy climbing & secure descents

Aheadset’s patented threadless steering system not only saves weight, but pre-loading the headset bearings for optimal steering precision is much easier than on standard threaded headsets

The 26 x 1.95″ XC knobbies on our Trail X-series bikes are from the same manufacturer that produces Maxxis tires: one of the most respected names in off-road rubber in the business

The Trail X-series broad-based ATB saddle with front & rear protective guards offers plenty of comfort, durability & style

Dakar XC is our most pedigreed chassis, featuring the legendary Jamis Dakar mp2 suspension that’s won races, industry awards, and glowing accolades from the cycling press and the pedaling public for years. With all our years of refinement and tweaking, this is the epitome of dialed-in performance.

But awards mean nothing out on the trail, and that’s where the Dakar XC seriously shines. A nearly vertical axle path lets the suspension follow every terrain contour smoothly, providing incredible traction as it takes the edge off terrain hits, with an optimized structure and perfect pivot placement for that brand of precision control that makes it easy to follow that perfect line.

The original Jamis Dakar multi-link suspension platform, refined throughout the years, has won numerous industry awards & accolades, as well as multiple World Cup & NORBA National titles.

Dakar XC’s suspension system is fully active with a near-vertical wheel axle travel path, plus excellent lateral & torsional stiffness for rear wheel tracking precision.

X-fusion’s Glyde R hydraulically damped coil-spring shock is plush with externally adjustable rebound damping. The XC offers 3 spring rates: 450 lbs (13 – 15″), 550 lbs (17 -19″) & 650 lbs (21 – 23″).

RST’s Gila Pro features TnL damping, a hydraulic cartridge damping system with a compression-to-lockout function, and big 30mm stantions for precise steering & handling.

The best shifting drivetrains are 100% integrated from one manufacturer. Dakar XC offers just that with a Deore rear derailleur, Alivio 24-speed RapidFire Plus SL shifters, HG40 cassette, and Hyperdrive SG-X chainrings: all from Shimano and all delivering in tandem exceptionally precise & quick shifting performance.

Shimano’s new Deore Shadow derailleur features a QUIET super low-profile design that won’t slap the chainstay in rough riding conditions. Direct cable routing reduces the risk of housing snag.

Shimano’s splined Octalink BB and crank interface offers much greater strength & rigidity than standard square taper designs, thanks to the increase in contact area between BB spindle & crank arm.

Tektro’s IO disc brakes stop great in all conditions & increase wheel longevity by eliminating the rim sidewall from the brake system.

Disc hubs twist when disc brake calipers hub rotors during stops. This hub twisting increases “pull” load on the nipples in the spoke bed. The Alex TD25 spoke bed is cleverly reinforced to resist disc brake torque and prevent spokes & nipples from shearing at the spoke bed.

Geax is quickly making a name for themselves in the offroad world and their Saguaro tires ride exceptionally fast, with low rolling resistance, thanks to the central ridge of uninterrupted knobs.

The XC Sport’s cockpit includes 31.8 over-sized bars and stem for stiffer, more solid steering & handling, and a 31.6mm seat post for a firmer pedaling platform

Our new Jamis Trail saddle offers an extra wide rear platform to support riders of all shapes, with extra long rails to promote a better fit.
