Dartmoor Primal Pro 29-inch trail mountain bike — lower the saddle for descents and choose your gear for the climb:

Key features

• Wheel size: 29 in
• Frame sizes: Medium, Large, XL
• Fork: Marzocchi Bomber Z2, air spring, 140 mm travel
• Drivetrain: SRAM Eagle 70 Transmission 1 x 12, 10–52T cassette
• Brakes: SRAM DB6 hydraulic, four pistons, 180 mm SRAM Centerline rotors
• Seatpost: X-Fusion Manic dropper
• Pedals: Not included; buy separately
• Weight: 14.10 kg without pedals

Pedal up, then lower the saddle

The X-Fusion Manic dropper lets you lower the saddle for more room to move on a descent, then raise it again for pedalling. Travel is 150 mm on Medium, 170 mm on Large and 200 mm on XL. Check that the post’s adjustment range gives you the saddle height you need.

Set the fork for your weight

The Marzocchi Bomber Z2 uses an air spring and has 140 mm of travel. Set it up according to the fork instructions and your weight, with help from a suspension workshop if needed. The Primal is a hardtail, so there is no rear suspension to set or service.

One shifter, a wide choice of gears

The SRAM Eagle 70 Transmission drivetrain combines a 30T chainring with a 10–52T twelve-speed cassette. That gives you a choice of ratios for climbs and faster sections, using one shifter and no front derailleur.

Four-piston SRAM DB6 hydraulic brakes use 180 mm SRAM Centerline rotors. Have the brakes adjusted and check their operation before every ride. The tubeless-ready Patrol rims give you the option of a compatible tubeless setup; check the tyre compatibility and use the required tape, valves and sealant.

Compare your riding position

The suggested rider heights are approximately 170–180 cm for Medium, 180–190 cm for Large and 190–200 cm for XL. Also compare reach, standover clearance and saddle adjustment with a bike you already know. Choose trails and features within the bike’s intended use and your ability.

Pedals are not included, so choose a suitable pair before riding.

Frame geometry

Measurements are in millimetres unless marked in degrees. The figures below use a 140 mm fork. Actual top tube length (TT) is not specified.

Inspect the bike after a hard impact and stop riding if you find looseness, cracks or damage. Have any problem checked and repaired before riding again.

Wear a properly fitted helmet and suitable protective pads. Read our important information before buying and using a bike for assembly, servicing and riding checks.
