At a glance

The most importanten ratings of the Focus JAM² 7.8 in comparison to the competitor bikes of following categorie: (5000) .

As the hits get faster and harder the average chassis limits the downhill fun. The mid-range brakes from Shimano do their job but could be a bit firmer. The power of the four pistons setup is only average. At the drivetrain components and the rest of the parts, Focus uses average parts. The handling of the bike is pleasantly balanced due to the moderate geometry. This allows you to intuitively control the bike over the trails. The low bottom bracket height will likely be a sticking point for trail riders, as it negatively affects handling. Due to the short chainstays , when climbing steep sections, it requires active weight shifting to prevent the front wheel from lifting.
