2021 Jamis Faultline A2 Dual Suspension MTB

This bicycle come with 12 months free service.

The mp2 suspension system is active with a near vertical wheel axle travel path, plus excellent lateral & torsional stiffness for rear wheel tracking precision.

Jamis' proven MP2 rear suspension design, which has won multiple bicycle industry accolades and Bike of the Year Awards is now available with 29 inch wheels in the Faultline series.


Riding fast with control requires steering precision, which starts with the front of the bike. Stiffening this area results in less wheel deflection, more wheel control. A tapered 1 1 /8” to 1 1 /2” head tube serves up a significant increase in rough terrain tracking and stability without much of a weight penalty compared to standard 1 1 /8” systems.


The chainstays are asymmetrical, with an elevated straight stay on the non-drive side and a dropped curved stay on the drive side. The drive side must be dropped & curved to clear the chain, but running the non-drive side straight from the dropout to BB pivot reduces weight while significantly stiffening the rear triangle laterally.


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.


Top-notch braking shouldn’t break the bank. Shimano’s hydraulic brakes offer the power, the smooth modulation and all-day, all-conditions reliability.


Rock Shox Deluxe and Monarch shocks offer adjustable rebound damping and a single valve air spring . It’s light and easily adjusted to suit rider and riding style.



The 1x drivetrain philosophy is to make it simpler, lighter and more durable. Specific  chainring tooth profiles, clutch-type rear derailleurs and wide range cassettes are developed for an incredibly wide gear range and maximum control without the need to chain tensioning devices or guides.


Securing the rear wheel to the frame by threading a 12mm axle into the rear drop-outs is not only safer, it’s stiffer.  The rear wheel tracks directly in line with the frame, for more precise handling, so you can go faster with more confidence. The increase in stiffness of a 15mm fork axle improves steering & handling significantly. It also puts less stress on the fork’s internals, improving fork durability and performance. The hub drop outs provide a self centering feature for the wheel for fast, easy installation.
