COVID-19 Important collection and delivery information

Due to a combination of new working practices and demand our lead times for both collection and delivery have been extended.

Where delivery times are stated as a month this is based on the latest information from the manufacturer. These dates should be treated as a guide and may be subject to change. Due to an increase in global demand for bicycles and the disruption in supply during the COVID-19 pandemic supply chains have become very strained. Lead times are based on factory and shipping schedules both of which can be disrupted by delays in component supply and shipping/port capacity.

Should you place a future order with us for a bicycle we will monitor the bikes ETA and keep you informed of any changes.

For more detailed information please read here.

This Trek Marlin 8 Alpine Blue 2022 is available with our legendary Podium Point free accessory scheme.

The Marlin 8 is a race-worthy mountain bike that won’t break the bank. The smooth, lightweight RockShox fork, tubeless-ready wheels and wide-range 1x drive train make this model the best choice for new riders who want a fast cross-country hardtail that will hold its own against higher-end race bikes.

A light frame with internal cable routing, a smoother-feeling RockShox Judy Silver fork with a Solo Air spring and TurnKey hydraulic lockout, Shimano hydraulic disc brakes, tubeless-ready Bontrager Kovee wheels and a simple 1x12 drivetrain that ditches the front derailleur for less clutter and easier operation. The wide-range 11-50 cassette gives you all the gears you need for clawing up climbs and blazing down descents.

The tubeless-ready wheels, RockShox suspension, wide range of gearing and quality parts make it an outstanding choice for new mountain bikers who know they want a serious bike for their money. It’s fully capable of taking on big trail adventures and XC races.

The Marlin models in XXS to S frame sizes have a curved top tube and a lower standover height that makes it easier for smaller riders to mount and dismount. To allow for an optimised frame fit the XXS size features 26" wheels, XS and S feature 27.5" wheels and larger sizes feature 29" wheels.

Note: This bike features Bontrager's Tubeless Ready rim system which enables a straightforward conversion to a full tubeless set up. To complete the conversion to tubeless you will need to fit additional parts. This include specific rims strips (W406892 for 29", W433382 for 27.5"), valves (W250324) and, appropriate tubeless tyres and sealant.

IMPORTANT: This bicycle requires a suspension pump to set and tune its suspension correctly. This is not included as standard. A suspension pump can be selected for no cost using Podium Points™.

This takes no account of a rider's personal proportions, physique, flexibility and biomechanics. If your height places you on, or near, a bicycle size step then we recommend you consider both sizes. All bicycles offer a range of handlebar and saddle adjustment which will enable you to fine tune your riding position once the correct size has been established. If you are unsure on sizing, we strongly recommend you visit our store so we can assist you. Pedal On offers advice and information on sizing in good faith, the final decision and responsibility on which size to purchase is yours.
