The bike is available now

Calibre Bikes has released the Astronut dirt jump bike.

The bike has a 26 inch 6061 hydroformed alloy frame with sliding brake mount, Manitou circus sport forks and a two-piece, cromo spindle chainset.

The brakes are Taektro Hydraulic disc with 160mm rotor, the rims are 26-inch double wall and the tyres are Schwalbe Table top 26 x 2.25.

The bike also features a pivotal saddle and alloy pivotal 30.9 200mm seatpost.

It also has a half link chain to allow for fine-tuned adjustment of the rear centre length.

Calibre Bikes said the Astronut is a "fun and capable jump bike", designed with a slightly longer toptube to be stable at speed and feel more natural for mountain bikers.

The Astronut is available now.
