Focus is launching its new "Jam" all-mountain bike with the same rear triangle concept as the "O1E" cross-country fully: the one-piece rear triangle paired with the F.O.LD. damper linkage. The main frame also has practically the same details as its lighter brother, the O1E, and yet there are clear differences between the two bikes. The chainstays of the carbon rear triangle of the top model, as well as those of the aluminum versions of the other models, are very short at 425 millimeters, making the bike more playful and easier to maneuver in tight passages. The F.O.L.D. linkage of the shock is technically the same, but comes in aluminum on the Jam.

Geometry for up and down

The Jam is clearly designed for downhill fun. This starts with the short chainstays and ends with the slack steering angle of 66.8 degrees. But the all-mountain bike should also be easy to ride uphill. At 74.5 degrees, the seat angle of the carbon frame, which weighs just 2060 grams, is just as steep as that of the O1E and should play into the hands of power transmission.

Six Jam models

Focus offers the Jam models "C SL" with carbon frame and rear triangle, "C Factory" and "C Pro" with carbon main frame and aluminum rear triangle as well as the aluminum versions "Lite", "Evo" and "Elite". The Jam "C SL" comes with Sram's new XX1 Eagle 12-speed drivetrain, the Rock Shox Pike RCT3 suspension fork with 140 millimeters of travel and XM 1501 Boost wheels from DT Swiss.
The Factory C model has an aluminum rear triangle and front suspension with a Rock Shox "Yari RC" with 150 millimeters of travel. The increased travel also flattens the steering angle slightly to 66.3 degrees. A Sram GX is used as the shifting group, combined with the new Descendant carbon crankset from Truvativ. The "Factory C" also rolls on DT Swiss XM 1501 wheels with 30 millimeter rims. The third carbon model with aluminum rear triangle is shifted with Shimano's XT groupset and the E 1900 CL from DT Swiss is used as rolling stock. Instead of a Rock Shox, a brand-new 34-Float performance fork from Fox is used at the front - with a Float DPS shock from the same company at the rear.

The Jam Lite is the first all-aluminum model. It is available in black and red. It is equipped with Sram's XO1 groupset, the Rock Shox suspension elements "Yari RC" and "Monarch RT" and Focus' own Concept EX wheels. The Jam "Evo" also comes with Rock Shox Yari and Monarch. The aluminum model under 3000 euros is specified with Sram's GX groupset. Compared to the last two models, the cheapest model, the Jam "Elite", comes with a Sektor Silver RL fork from Rock Shox and changes gears using Shimano's SLX groupset. Concept EX wheels are also used for the wheels.
