Bicycle Cross Prolog 28", Size 21.5"(55cm), Black

The frame is sturdy, with a geometry similar to a mountain bike, but with a more upright seating position than a mountain bike - less strain on the arms and better visibility. For longer journeys, often adapted to fit a variety of accessories such as mudguards and racks.

The wheels are robust, suitable for a wide range of terrain and for fitting wide tyres. Ideal if you like to ride on tarmac as well as on forest tracks. The 28" wheel size is suitable for longer journeys.

Front shock absorbing fork for comfort, better grip on varied terrain, avoiding obstacles, and safer downhill descents.

Tyres are available in a variety of tyre widths and patterns to suit the journeys you will make. Often the lightness and durability of the tyre are taken into account. Thicker tyres allow a wider range of surfaces.

The chain is partially hidden under the chain guard or a scratch guard is placed on the frame. Usually left relatively open for easy access when replacements are needed.

Plastic mudguards are often added to keep the overall weight of the bike to a minimum to accommodate the optional luggage rack.

Saddle narrower, stiffer (compared to city bikes) for a sportier seating position.

Both dynamos for comfort and separate battery lights to maintain a lighter construction.
