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 bike’s ETA and keep you informed of any changes.
Size Options & Purchase
Please note that we are unable to ship this Trek X-Caliber 8 Red outside of the UK. This is at the request of Trek Bicycles.
This Trek X-Caliber 8 Red 2021 is available with our legendary Podium Point free accessory scheme.
Trek's X-Caliber is the go-to cross country hardtail mountain bike built for speed, efficiency, and quick handling. The Alpha aluminium frame was heavily revised in 2020 and is the class leading chassis.
The X-Caliber's Alpha Gold aluminium frame set features modern tube profiles, cleaner internal cable routing and key performance features such as a 100mm travel XC fork, tapered headtube and Boost141 hub spacing.
X-Calibers feature Trek's Smart wheel sizing which means the wheel size is matches to the rider height to best optimise geometry and rider fit. This means 27.5" wheels on XS and S and 29" on larger frame sizes.
X-Caliber 8 features SRAM's 1x12 SX Eagle drivetrain with a huge gear range and positive shifting. Up front, suspension is courtesy of Rock Shox's Judy Silver air fork which is both light and easy to tune.This model also has tubeless ready rims that make it easy to upgrade.
If you're looking for a fast cross country hardtail with high style and a low price, then X-Caliber is the one.
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™.

Sizing information is provided as a general guide only. This is based on the average rider riding the bicycle in the style for which it is intended. 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.
