Description

The 24" Extention Avenger is Extention’s flagship carbon fibre street trials bike, designed for riders who want the lightest possible setup without sacrificing stiffness, precision, or durability. Featuring a full carbon frame, fork and handlebar combination, the Avenger delivers an incredibly responsive ride feel with explosive power transfer and razor-sharp handling.

The Avenger combines a short wheelbase, compact rear end and steep head angle to create a bike that feels perfectly at home on technical street lines. Internal brake hose routing keeps the front end clean for whips and bar spins, while the carbon chassis provides exceptional rigidity for maximum control on rear-wheel moves.

Weighing in at under 9.3kg, the Avenger ranks among the lightest production 24” street trials bikes available. The frame’s responsive character rewards aggressive riding while maintaining the stability needed for precision balance and technical control.

The bike is equipped with a premium selection of Extention CNC-machined components, including BB30 cranks, integrated bashring, forged high-rise stem and carbon riser handlebars.

Warranty
This bike is supplied with a 6 month warranty which covers manufacturing defects. Warranty does not cover mistreatment or poor maintenance. The owner is responsible for ensuring that components are not allowed to come loose as this increases the chance of damage to threads and tapers. It is recommended that owners check that their bike is in good working order before and after each ride - trials bikes are more prone to parts becoming loose because of the type of riding they are subject to.
