Focus may be best known for its road and cyclocross offerings, but the company has invested heavily in the development of its mountain bikes in recent years. The latest addition to the German company’s off-road line is the Spine, a 27.5in trail bike with 120mm of front and rear travel wrapped up in a lightweight, single-pivot package.
- Four carbon and six alloy models (two of the alloy versions are women’s-specific)
- 27.5in wheels
- 120mm of front and rear travel
- Carbon frame weight: 1,980g (claimed)
- Alloy frame weight: 2,450g (claimed)
- Four frame sizes (S-XL)
- Pricing: TBA
- All models available in August 2015
The Spine takes many of its design cues from the 160mm travel SAM. It sports an oversized junction where the head tube meets the top and down tubes to bolster front-end stiffness. Likewise, the single-pivot suspension relies on double rows of bearings at the rear pivot to keep flex in check.
According to Focus engineers, single-pivot suspension designs that place the shock inline with the top-tube can suffer from inconsistent suspension performance between frame sizes. This is due to the fact that the orientation of the link driving the shock can change as frame size increases. To combat this discrepancy, Focus employs different composite links for each frame size to keep the suspension rates relatively similar, though not exactly the same. Large and XL frames get a slightly more progressive shock rate to provide better performance for heavier riders.

Ports on the head tube allow for a variety of cable routing options
Both the alloy and carbon versions of the new bike share internal cable routing through ports on the side of the head tube. Different versions of these ports will be available for mechanical and electronic drivetrain configurations.
