The 2019 Scott Genius gets several upgrades, with top models adding the latest 4-piston XT and XTR Shimano brakes. And there will be a bike with the new XTR group shipping later this year. The frame stays the same and continues to use their adjustable travel system, switching from 150mm to 110mm to locked out by controlling the air volume. Basically, by reducing the volume, the shock ramps harder in the middle setting and effectively creates a shorter travel bike. It’s a system they’ve used for years and works well. Adding to that, though, is a very interesting new adjustment feature…
They have a new high volume rear shock with a proprietary TR lever that opens or closes access to a secondary air chamber. That lets you tune the progressiveness of the shock, which is basically a ramp adjust. Open it up and you have a bigger air chamber with a more linear response. Close it and it’ll ramp harder. They also have more overall volume than the prior EVOL shocks used, so they can handle heat buildup better.
The shock is marked with “Progressive” on one side…
…and Linear on the other, with graphics to help explain it in case you’re not as familiar with the terms.
