Jamis Highpoint A1 2021 MTB
This bicycle come with 12 months free service.
Lightweight and strong triple-butted 6061 series aluminum tubing, featuring over-sized & tapered tubing for increased frame stiffness.
TAPERED HEADTUBE
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 full 1.5 head tube and steerer would achieve this, but would add unnecessary weight and bulk, and limit stem choices. But 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.
WHY THRU AXLES?
The increase in stiffness of a 15mm fork axle improves steering & handling significantly. It also puts less stress on the forks internals, improving fork durability and performance. The hub drop outs provide a self centering feature for the wheel for fast, easy installation.
ONE & ONLY
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.
TOP TUBE CABLE ROUTING
Running the cables up under the top tube keeps cables and housing out of the muck for more precise and reliable shifting performance.
DUAL WATERBOTTLE MOUNTS
Most of our Highpoint sizes offer two water bottle mounts located inside the main frame. This provides excellent hydration capacity in an easily accessible position.
