Sharing a chassis with the barnstorming Rake 29” bike, the Calibre Rail is a big-wheeled bike that performs like a proper modern mountain bike, but for a lower price. The combination of its steep seat angle and slacker head angle creates a great climber and a confident hill bomber; it’s a composed ride that’s great for anyone starting out. Suspension on this hardtail is taken care of by a fuss-free, coil-sprung Suntour XCM fork with100mm of travel.

The Rail’s Shimano drivetrain works well with the handsome tan-walled OBR tyres to create speed and keep you in control. Its Clarks M2 hydraulic brakes provide ample stopping power in all conditions. Altogether, this bike is far more capable than its price tag suggests -it’s a budget all-rounder and a team favourite.
