Description
This Trek Rail+ 8 Gen 5 Dark Star is available with our legendary Podium Point free accessory scheme.
Please note: This model features tubeless ready wheels and tyres which offer a superior ride and less rolling resistance than traditional innertubes. This system requires tyre sealant to function correctly and this will be fitted in our workshop prior to despatch. The nature of this sealant means that the tyre may not be fully sealed until it has been ridden a short distance and therefore the bicycle may arrive with reduced pressure in the tyres. Please check the bicycle's tyres are inflated to the recommended pressure before cycling.
Please note: This model offers electric assistance up to speeds of 25kph (15.6mph).
IMPORTANT: This bicycle is supplied without pedals. Pedals for this bicycle can be selected for no cost using Podium Points™.
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.
