”The original aim of the Switchback was to design the most playful natured and confidence inspiring aggressive frame that we possibly could.”

This statement has become the design ethos that underpins the whole of the Stanton Switch frame range, with our newest offering to the market being the Switchback FS 27.5″.

The Switchback FS is our 27.5” wheeled frame, with kinematics designed to reflect the positive ride characteristics evolved from our award winning Switchback 631 and Ti hard tail frames.

Burst acceleration, stoically stable descending, agility in the corners and eye watering pace, the Switchback FS 27.5” has all these characteristics in abundance. It is as happy being thrashed down bike park black runs as it is racing the Mega Avalanche.

Our progressively designed suspension allows for a bottomless feel, while the dual link pivot system aids small bump control by allowing rearward movement as the back wheel travels through the start of the suspension arc.

This model is our 140mm aggressive Trail bike.

Comes with the Marzocchi Bomber CR Shock.

This guide is a basic structure to how we feel the frames should fit. However, sizing a bike is a very personal thing and many factors should be taken into consideration.

For instance, if you’re around 5’10″ and you’re used to larger bikes, the 18″  might suit you better than the 16.5″.

If you’re a bit taller, around 6′2″, with a riding style that’s nimble, playful and aggressive, and you’re looking to do no more than short trail-centre loops or smash DH runs in the woods, the 18″ should suit you better than the 19.5″.

We took our freshly finished U.K made Switchback FS down to Dan Bateson in Woburn to see what he thought of it. He got on with it very well…
