A 27.5” all-mountain bike with 140 mm travel, the FOCUS JAM is the latest young sprog to join the successful FOCUS trail family as a bike that’s made for a never-ending off-road adventures on technical terrain. Equally at ease on hardas- nails home trails as well as burly mountainous turf, it’s a mesmerising all-rounder with numerous standout traits: the FOCUS typical design language, aggressive all-mountain geometry and the all-new F.O.L.D. rear suspension design.
Vast landscapes with solitary singletracks set amongst a backdrop of majestic mountains. Alpine hairpin descents and intense, technical uphill climbs that demand every ounce of concentration. These are the rides that ask for reliability, for fearlessness and the ability to conquer all types of terrain. It’s mountain biking at its purest, at its most undiluted. The 27.5” all-mountain FOCUS JAM with its 140 mm of travel is destined to take you on your most epic riding adventures.
FOCUS OPTIMIZED LINKAGE DESIGN
A further indulgence for any rider comes from the JAM’s use of the new FOCUS F.O.L.D. rear suspension design. The responsive F.O.L.D. design generates enormous amounts of traction and willingly absorbs bumps, acting as a huge confidence-booster for entry-level all-mountain riders. For more advanced riders, this same fusion lends itself to aggressive, more dominating riding even on the toughest terrain. But whatever the ability, all riders will appreciate how the low centre of gravity and playful handling keeps the bike planted on all terrain.
All suspension hardware is located in the frame’s center. The resulting low center of gravity enables superb handling that gives you extra confidence, especially on technical terrain and cornering. The optimized centralised mass affects the riding dynamic as well as the great handling of the bike.
TWO-PHASE TRAVEL ARRANGEMENT
The system’s travel is divided in two phases. Within the first phase of travel, the system works degressively for super sensitivity, thereby eliminating microbumps and generating immense grip. The second phase of the travel offers fine tuned progression for both plushness and feedback while still ensuring enough bottom-out resistance. So the rider is always in control of the bike. To match this technology and to generate the ultimate riding performance we use only dedicated tuned shocks.
Developed in-house in Stuttgart, the carbon fibre chassis isn’t just super stable, but also super lightweight at just 2060 g (size M). One of the key design elements of this frame is the muscular front end, where the top tube seamlessly flares into the head and down tube to create a super stiff and ultra responsive ride, even at high speeds. Boost 148 and Boost 110 hub standards ensure stiffer and more stable wheels. As expected, the high quality FOCUS bearings, including those in the F.O.L.D. rear suspension design, are a welcome sight. And the same applies to the FOCUS JAM’s smooth suspension and outstanding durability.
This all-mountain new entrant from FOCUS has modern geometry that exacts an aggressive riding style, with the generous reach (size M: 435 mm) allowing for rapid weight shifting to meet the gradients. With its compact 425 mm chainstays, the FOCUS JAM has a healthy pop to it, injected with agility and a slack 66.8° head angle and buttery smoothness for unadulterated downhills. However, not confined to descents, the product developers took it further and engineered a bike that can climb with equal prowess: the steep, ergonomic seat angle of 74.5° guarantees efficient pedalling, drawing out the bike’s nimble side. As a result, the refined geometry and playful ride make the FOCUS JAM more than capable of everything from trail quickies to multi-day Alpine rides with a ton of pedalling.
FOCUS’s obsession with details is always at the benefit of the riders and runs ceaselessly though the spec list of the six JAM models, with each model sporting a dropper post to deliver uninterrupted trail flow for the rider. The ISCG 05 tab on the bottom bracket allows a chain guide to be mounted effortlessly; who can argue with the benefits of avoiding unwanted chain drop on gnarly terrain. The FOCUS JAM models also show consideration for various rider levels – unlike the other models, the JAM C Pro and JAM Elite both house a regular 2x drivetrain. The three aluminium JAM models, the two carbon-framed JAMs with an aluminium rear, as well as the full carbon JAM C SL model all come in four frame sizes, meaning everyone can exploit its advantages.
