Dartmoor Primal Pro 27.5-inch trail mountain bike — lower the saddle for descents and choose your gear for the climb:

Key features

• Wheel size: 27.5 in
• Frame sizes: Small, Medium, Large
• Fork: Marzocchi Bomber Z2, air spring, 140 mm travel
• Drivetrain: Shimano Deore M5100 1 x 11, 11–51T cassette
• Brakes: Magura MT Thirty hydraulic, two pistons, 180 mm rotors
• Seatpost: X-Fusion Manic dropper
• Pedals: Not included; buy separately
• Weight: Approx. 13.70 kg

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 125 mm on Small, 150 mm on Medium and 170 mm on Large. 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 Shimano Deore M5100 drivetrain combines a 32T chainring with an 11–51T eleven-speed Sunrace cassette. That gives you a choice of ratios for climbs and faster sections, using one shifter and no front derailleur.

Two-piston Magura MT Thirty hydraulic brakes use 180 mm 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 160–170 cm for Small, 170–180 cm for Medium and 180–190 cm for Large. 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.

Safety while riding

Riding, falls and impacts put loads through the bike and can damage components. No bike is indestructible: parts can wear out or become damaged. Check the frame, fork, bars, wheels, axles, cranks, pedals, brakes and bolted connections before every ride. 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.
