Upgrades from Checkpoint ALR 3: - 1x11 speed SRAM APEX 1 drivetrain Details: - High performance: Highly engineered 300 Series Alpha Aluminium frame - Trek's premium aluminium, formed into sophisticated tube shapes for maximum strength and minimum weight. Revolutionary Invisible Weld Technology offers a better connection at each tube junction, increasing strength while using less material. The results are smooth and flawless seams, stronger bonds between the frame's tubes, sparkling aesthetics, and decreased frame weight. - Tapered headtube: The fork tapers from a 1.5" lower bearing to a 1 1/8" upper bearing. The larger-diameter lower bearing keeps the fork stiffer under cornering loads and distributes forces more evenly, increasing the life of the bearings. Result: a more confident and durable ride. - Flat Mount Brakes: more elegant, lighter, smaller and cleaner than traditional disc brakes. - 3S integrated chain keeper is integrated directly into the bike frame. It's an elegant solution that provides flawless gear shifting even on rough roads and under heavy loads. No more standing on the side of the road, covered in grease, unwedging your dropped chain as competitors race by. - Blendr Integration: Blendr seamlessly mounts Bontrager Trip computers, Bontrager Ion lights and Garmin computers directly to the handlebars, keeping everything zip tie-free and in its place. - Mudguard and pannier rack compatible: Mudguard mounts allow for full-coverage mudguards so you can ride comfortably in less-than-ideal conditions. Rack mounts enable Checkpoint ALR to become your favourite commuter or touring bike. Next model up: Checkpoint ALR 5 |
